Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer and more complete, the technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention, and based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the scope of the present invention.

As described above, in the related art, a plurality of Network devices need to be divided into different Virtual Local Area Networks (VLANs) to facilitate management of the Network devices. For example, an enterprise may include 20 hosts, 2 for financial, 3 for administrative, and 15 for research and development. The 20 hosts can be divided into different virtual local area networks according to different work types for networking, such as VLAN1, VLAN2 and VLAN 3. However, whether the network topology formed by the network devices is successfully networked according to the networking scheme or not can be determined by manually inquiring the network configuration information on the network devices in the related art, and the detection efficiency is low. In view of the fact that network access can be achieved among network devices in the same virtual local area network after networking is completed, it is considered that a device in the same virtual local area network as the network device initiates access to the network device, and the state of the network device, such as online or offline, is determined according to an access result to determine whether networking of the network device is successful.

Specific implementations of the above concepts are described below.

Referring to fig. 1, an embodiment of the present invention provides a method for detecting a network topology state, where the method includes:

step 100, determining the topology of an entity network to be detected; the physical network topology includes a plurality of network devices;

102, acquiring networking information corresponding to the plurality of network devices respectively;

104, creating virtual detection equipment which belongs to the same virtual local area network as each network equipment according to the networking information respectively corresponding to the plurality of network equipment, and initiating access to the plurality of network equipment by using the virtual detection equipment so as to determine the state of each network equipment according to an access result;

and step 106, determining whether the entity network topology is successfully networked according to the state of each network device.

In the embodiment of the invention, after the entity network topology is networked, the devices belonging to the same virtual local area network can be accessed, and the virtual detection device and each network device belong to the same virtual local area network by creating the virtual detection device, so that the virtual detection device can be used for initiating access to the network devices which belong to the same virtual local area network, the state of each network device can be determined according to the access result, and whether the entity network topology is successfully networked or not can be determined. Therefore, the scheme can automatically complete detection without human participation, and therefore, the detection efficiency can be improved.

The manner in which the various steps shown in fig. 1 are performed is described below.

Firstly, aiming at step 100, determining the topology of an entity network to be detected; the physical network topology includes a plurality of network devices.

For the purpose of describing the present embodiment, two concepts are introduced here:

entity network topology: the network topology is a network topology formed by physically connecting the plurality of network devices after networking. In the physical network topology, the connection relationship among the plurality of network devices is referred to as a physical connection relationship.

Simulating a network topology: the network topology is formed by adding the plurality of network devices to a topology editing page of drawing software in a corresponding graph mode in drawing software which can be used for drawing a topology graph, and then connecting the graphs of the network devices by using connecting lines. In the simulated network topology, the connection relationship between the plurality of network devices is referred to as a simulated connection relationship.

In the embodiment of the present invention, after the entity network topology is networked according to the set networking scheme, in order to determine whether the entity network topology is successfully networked, the states of each network device in the entity network topology need to be detected.

A network device is a physical entity connected to a network, such as a computer, hub, router, switch, firewall, bridge, gateway, printer, camera, etc.

Networking is a network construction technology, and a plurality of network devices can be divided into different VLANs. For example, the set networking scheme is to divide 10 hosts into 3 VLANs, wherein hosts 1 to 3 are divided into VLAN1, hosts 4 to 6 are divided into VLAN2, and hosts 7 to 10 are divided into VLAN 3. These hosts are all connected to a switch, which may be one switch or a plurality of switches. When VLAN partitioning is performed, it needs to be performed by at least one switch connecting these hosts.

In an embodiment of the present invention, in order to implement fast networking and manage a networked entity network topology, before this step 100, please refer to fig. 2, which may utilize one of the following manners to network the entity network topology according to a set networking scheme, specifically including:

step 200, determining a networking scheme required to be realized by the plurality of network devices; the plurality of network devices includes at least one switch.

Step 202, obtaining a simulated network topology corresponding to the networking scheme. The simulated network topology includes simulated connection relationships among the plurality of network devices and networking information of each network device.

In this step 202, when obtaining the simulated network topology corresponding to the networking scheme, the following two cases are included:

in the first case: there is no physical network topology at this time.

In the second case: there is now a physical network topology.

The requirements for simulating the network topology are different when the different situations are met.

In the case of the first case, since there is no physical network topology, it indicates that the network device has not been physically connected. At this time, a connection relation can be obtained for the plurality of network devices according to the networking scheme, so that a connection mode of physical connection is simple, and a simulation connection relation in the simulation network topology is formed. After obtaining the simulated connection relationship in the simulated network topology, the plurality of physical devices need to be physically connected according to the simulated connection relationship to form the physical network topology.

When the second case is used, the entity network topology exists at this time, and the entity network topology may include two cases: in the case A, the entity network topology already networks the network equipment, but the networking scheme is different from the networking scheme required to be realized at this time, namely the networking scheme needs to be changed; and in case B, the entity network topology does not carry out networking on the network equipment. However, in the case a or the case B, the entity connection relationship of the entity network topology does not need to be changed, and when networking is performed or networking is changed, a switch needs to be used to complete a networking scheme to be implemented. Therefore, in response to the second case, the simulated network topology needs to connect the plurality of network devices on the topology editing page according to the entity connection relationship in the entity network topology to form the simulated connection relationship in the simulated network topology.

In summary, whether the first case or the second case is used, it needs to be ensured that the simulated connection relationship in the simulated network topology is the same as the entity connection relationship in the entity network topology.

In an embodiment of the present invention, the manner of obtaining the simulated network topology corresponding to the networking scheme at least includes the following two ways:

the first mode is as follows: the simulated network topology is newly drawn.

The second mode is as follows: and obtaining the simulated network topology by utilizing the stored template.

The following describes the above two modes, respectively.

This step 202 uses the first approach to obtain a simulated network topology.

Referring to fig. 3, the present step may include:

step 300, obtaining device packages respectively corresponding to the plurality of network devices on a pre-created topology editing page, and connecting the device packages to obtain a simulated connection relationship between the network devices.

In one embodiment of the present invention, the mapping software may provide a topology editing function, and in response to an operation instruction input by a user, the mapping software may obtain a plurality of device packages on a topology editing page, and connect the device packages to obtain a simulated connection relationship between a plurality of network devices.

Wherein the device package is used to characterize a feature set of the corresponding network device. The device package may include graphical elements and textual elements, and may also include interface elements.

The graphic elements are used for representing the graphs of the corresponding network devices, different types of network devices can use different graphic elements, and a user can determine the type of the network device corresponding to the device package according to the graphic elements of the device package displayed on the topology editing page. For example, the network device is of the type desktop, laptop, router, switch, firewall, camera, etc. The created graphic elements may be stored in a graphic library.

The Interface elements are used to represent each Interface included in the network device, for example, the network device includes a console Interface, an optical port, a USB Interface, a Type-C Interface, a Universal Asynchronous Receiver/Transmitter (UART) Interface, a High-Definition Multimedia Interface (HDMI), a Serial Peripheral Interface (SPI), and the like. In this embodiment, the interface element may be edited, for example, by adding a delete or change interface. The created interface elements may be stored in an interface library.

The text element is used for recording the packaging information of the network device, and the packaging information may include: hardware information and software information. The hardware information may include: device type, device identifier, interface type, interface identifier, device self parameter information (such as processor model, frequency, hard disk capacity, memory size, etc.), operating system information, etc., and the software may include: IP address, MAC address, vendor information, vendor ID, network device login information, etc. All the text description information of the network equipment corresponding to the equipment package can be stored in the package information through the edited text elements, and the package information is a part of the equipment package and can be displayed or hidden on a topology editing page according to different configurations. For example, when the packaged information is not viewed or edited, the packaged information is in a hidden state, and when viewing or editing is required, the packaged information can be displayed. The display mode can include: and displaying in a display window form or copying the packaging information to other video display units for displaying and the like.

The device package may be a package for one network device, or may be a package for connection relationships between a plurality of network devices.

Device packages may be pre-generated and stored in a package library. The packaging library can perform import, export, selection, editing, calling, deleting and other operations through the data interface.

In the embodiment of the invention, the graphic elements, the interface elements and the character elements of the network equipment are packaged together in an equipment packaging mode, so that the information in the equipment packaging is richer and more comprehensive, and when the simulated connection relation among a plurality of network equipment is drawn on the topology editing page, the graphic elements, the interface elements and the character elements in the equipment packaging can be quickly edited, thereby improving the editing speed of the network topology.

In this step, the manner of obtaining device packages corresponding to the plurality of network devices on the topology editing page may include at least the following three manners: 1. importing from a packaging library; 2. editing or creating on the topology editing page; 3. and copying and pasting the device package obtained on the topology editing page.

And the device package can be deleted, moved, rotated and the like on the topology editing page. The operations such as moving and rotating may be performed in a two-dimensional coordinate manner on the topology editing page.

In this step 300, the device packages are connected, specifically: the connection of the device packages may be accomplished using a connection element. The connection elements can be straight lines, curved lines, straight lines with arrows, curved lines with arrows and the like, and when the connection elements correspond to different types, the connection elements can be used for representing different types of links.

In an embodiment of the present invention, when the device packages are connected by using the connection element, the correspondence between the device packages and the connection element may be stored, which facilitates subsequent identification of the simulated connection relationship between the network devices. The method includes deploying a detection script in an equipment package in advance for detecting whether a connection element is connected with the equipment package, acquiring identification information of the connection element when the connection element is detected to be packaged in the equipment package and connected with the equipment package, determining a target element for the connection between the equipment package and the connection element, and storing a corresponding relation between the identification information of the target element and the identification information of the connection element.

When the device package does not include an interface element, the target element is a graphical element of the device package. For example, if the identification information of the graphic element is S01 and the identification information of the connection element is L001, the correspondence relationship between S01 and L001 is stored.

When the device package includes interface elements, the target element is one of the interface elements of the device package. For example, the device package includes two interface elements, the identification information of the two interface elements is S01001 and S01002, the identification information of the connection element is L001, and the target element establishing connection with the connection element is the interface element S01001, so that the corresponding relationship between S01001 and L001 is stored.

In storing, the correspondence may be stored in package information of the device package.

Step 302, configuring networking information for each device package on the topology editing page according to the information of the virtual local area network to which each network device is divided in the networking scheme.

In this step 302, the configuration manner of networking information for each device package may at least include the following two manners:

mode a, manually configuring networking information on the device package.

And B, automatically packaging and configuring networking information for the equipment.

Taking the example that the plurality of network devices includes a switch and 10 hosts, the 10 hosts are all connected to the switch. The information of the virtual lan may be VLAN numbers, for example, the 10 hosts are divided into VLAN1, VLAN2 and VLAN3, respectively.

In the method a, the networking information may be configured for the device package by editing the text elements of the device package. The networking information may include a VLAN number, an IP address assigned to the VLAN number, and the like.

Then, in the mode B, the step may specifically include: creating a boundary frame corresponding to the virtual local area network on the topology editing page; and when the target equipment package is detected to be positioned in the boundary frame, configuring networking information for the target equipment package according to the information of the virtual local area network corresponding to the boundary frame.

The created bounding box may be a closed box, and the bounding box may be configured to correspond to a virtual local area network. For example, the bounding box is configured to correspond to VLAN1, and when it is detected that a target device package is moved into the bounding box, text elements of the target device package may be automatically edited according to the information VLAN1 of the virtual local area network corresponding to the bounding box, so as to implement configuring networking information for the target device package.

By using the mode B, the device encapsulation of the network device belonging to the same VLAN can be rapidly moved to the boundary frame corresponding to the VLAN, and the configuration of networking information is automatically carried out on the device encapsulation of the network device belonging to the same VLAN, so that not only can the networking scheme required to be realized by a plurality of network devices be visually shown, but also the configuration speed of the networking information can be improved when more network devices are used for networking.

And step 304, determining the network topology formed on the topology editing page as a simulated network topology corresponding to the networking scheme.

In one embodiment of the invention, after step 304, the generated simulated network topology corresponding to the networking scheme may be stored in a simulated network topology library for subsequent use.

This step 202 uses a second approach to obtain a simulated network topology.

The simulated network topology obtained in the first way may be stored, for example, in a simulated network topology library, and then a plurality of simulated network topologies may be included in the simulated network topology library for selection.

Referring to fig. 4, the step 202 may include:

step 400, determining whether a simulated network topology corresponding to the networking scheme exists in a pre-generated simulated network topology library, and if so, executing step 402; if not, go to step 404.

In an embodiment of the present invention, when the simulated network topology is stored in the simulated network topology library, the networking schemes corresponding to the simulated network topology may be stored together. For example, the number, type, networking division condition, etc. of the network devices in the storage networking scheme. So that the user can quickly know whether the required simulated network topology exists in the simulated network topology.

If networking needs to be changed frequently in an enterprise, and the change range comprises several fixed networking schemes, the simulated network topology of each networking scheme can be stored in the simulated network topology library. When the network is changed, the simulated network topology corresponding to the networking scheme can be directly exported from the simulated network topology library, so that the networking change efficiency can be improved, and the networking change cost can be saved.

Step 402, deriving the simulated network topology corresponding to the networking scheme from the simulated network topology base.

Step 404, generating a simulated network topology corresponding to the networking scheme.

This step 404 generates a simulated network topology corresponding to the networking scheme, which is the same as the first method described above and is not described herein again.

Step 204, generating a networking password according to the simulated connection relation included in the simulated network topology and networking information of each network device.

In the embodiment of the invention, after the simulated network topology is formed, a user can initiate an instruction for mapping the simulated network topology to the entity network topology, after the system receives the instruction, the system can identify the simulated network topology, identify the contents related to the simulated network topology, such as the simulated connection relationship, networking information of each network device and the like, and then generate the networking password which can be identified by the switch according to the identified contents.

In an embodiment of the present invention, the identification manner of the networking information of the network device may include: directly obtaining the character elements of the equipment package, and extracting networking information of the network equipment corresponding to the equipment package from the character elements.

In an embodiment of the present invention, the identification manner of the simulated connection relationship may include: acquiring the corresponding relation between each equipment package and each connecting element; determining the connection relation among a plurality of equipment packages according to the corresponding relation; determining a connection relationship between the plurality of device packages as the simulated connection relationship.

For example, if the device package S01001 interface has a corresponding relationship with the connection element L001 and the device package S02001 interface also has a corresponding relationship with the connection element L001, it may be determined that the device package S01001 interface has a connection relationship with the device package S02001 interface according to the connection element L001.

When the corresponding relationship between each device package and the connection element is obtained, the corresponding relationship may be directly obtained from the package information of the device package (the corresponding relationship is stored in the package information in step 300). The device package may also be detected by using the detection method in step 300, so as to obtain the corresponding relationship between the device package and the connection element.

An example of a portion of the identifying content is given below:

the device type: switch

Identification information of the device: s01

Identification information of interface 1: s01001

Identification information of the device to which interface 1 is connected: d01001

Type of device to which interface 1 is connected: computer with a memory card

Type of interface of the device to which interface 1 is connected: net mouth

Identification information of interface 2: s01002

Identification information of the device to which the interface 2 is connected: d02001

Type of device to which interface 2 is connected: computer with a memory card

Type of interface of the device to which interface 2 is connected: net mouth

The device type: computer with a memory card

Identification information of the device: d01

Identification information of the device to which interface 1 is connected: s01001

Type of device to which interface 1 is connected: switch

Type of interface of the device to which interface 1 is connected: light port

VLAN information to which the device belongs: VLAN1

IP address of device: 168.192.0.1

The login account of the device: 111111

Login password of device: 222222

……

In an embodiment of the present invention, since the recognizable networking passwords are different when the models of the switches are different, different networking passwords need to be generated for different switches when generating the networking passwords. Specifically, this step 204 may include:

s1: and determining at least one network device connected with a target switch in the at least one switch according to the simulated connection relation, and determining information of an interface of the target switch connected with the at least one network device.

For example, the switch S01, the network devices connected thereto include device D01 and device D02, and device D01 is connected using the S01001 interface of the switch and device D02 is connected using the S01002 interface of the switch.

S2: and determining the attribute information of the target switch and the information of the virtual local area network to which the at least one network device belongs according to the networking information of each network device.

The attribute information of the target switch may include vendor information, model information, and the like.

When determining the information of the virtual local area network to which the at least one network device belongs, it may be determined from the networking information of the network devices, for example, the information of the virtual local area network to which the device D01 belongs is VLAN1, and the information of the virtual local area network to which the device D02 belongs is VLAN 2.

S3: and determining the password type which can be identified by the target switch according to the attribute information of the target switch.

In S2, after the attribute information of the target switch is determined, the password type that can be recognized by the target switch can be determined directly according to the corresponding relationship.

S4: and generating a networking password corresponding to the target switch according to the information of the interface of the target switch and the at least one network device, the information of the virtual local area network to which the at least one network device belongs and the password type which can be identified by the target switch.

After the networking scheme is determined, the generation of the networking password for the switch may be implemented by an existing scheme, which is not described in detail herein.

In the embodiment of the invention, the password types which can be possibly identified by different exchangers are considered to be different, and the password types which can be identified by the exchangers can be determined according to the attribute information of the exchangers so as to generate the networking passwords which can be identified by the interaction machine, thereby ensuring the successful networking.

Step 206, sending the networking password to the at least one switch, so that the at least one switch executes the networking password, so as to perform networking on an entity network topology formed by the plurality of network devices according to the networking scheme, wherein an entity connection relationship between the plurality of network devices in the entity network topology is the same as the simulated connection relationship.

When two or more switches are included in the plurality of network devices, the generated networking password corresponding to the switch may be transmitted to the corresponding switch. After the switch receives the networking password, the networking password can be executed, so that networking is completed.

The above steps 200 to 206 complete the networking of the entity network topology.

It should be noted that, besides the networking mode described in fig. 2, other networking modes may also be used, for example, a manual networking mode, that is, after the networking scheme is determined, the operation and maintenance personnel directly and manually configure the switch to implement networking.

In an embodiment of the present invention, the physical network topology in step 100 may be mapped from the simulated network topology. For example, the entity network topology after networking in step 200 to step 206 is the entity network topology to be detected in step 100.

Then, in step 102, networking information corresponding to each of the plurality of network devices is obtained.

In step 102, in order to implement the state detection of each network device in the entity network topology, networking information of each network device in the entity network topology needs to be acquired, and the networking information may be input by operation and maintenance personnel; or storing networking information of each network device in the entity network topology in advance, and directly reading the networking information from a storage position when the networking information is needed; in addition, the network topology can be obtained through a simulated network topology corresponding to a networking scheme implemented by the entity network topology.

When the network device is obtained through the simulated network topology corresponding to the networking scheme implemented by the entity network topology, specifically, encapsulation information that each network device respectively corresponds to device encapsulation is obtained from the simulated network topology, the encapsulation information includes networking information, and the networking information of the network device is extracted from the encapsulation information.

Finally, in step 104, according to the networking information respectively corresponding to the plurality of network devices, a virtual detection device belonging to the same virtual local area network as each network device is created, and the virtual detection device is used to initiate access to the plurality of network devices, so as to determine the state of each network device according to the access result.

In the embodiment of the present invention, the number of created virtual detection devices may correspond to the following two cases:

the first condition is as follows: a virtual detection device is created.

Case two: at least two virtual detection devices are created.

The following describes the implementation of this step for the above two cases.

In a first case, referring to fig. 5, initiating access to the multiple network devices by using the virtual detection device in this step 104 may include:

step 500, determining at least one virtual local area network corresponding to the plurality of network devices according to the networking information of each network device.

Step 502, determining whether there is a virtual local area network that is not detected in the at least one virtual local area network, if yes, executing step 504; if not, the detection is finished.

Step 504, selecting a virtual local area network from the undetected virtual local area networks as a target virtual local area network, and determining at least one network device belonging to the target virtual local area network and the IP addresses respectively corresponding to the at least one network device.

Step 506, allocating an IP address belonging to the target virtual local area network to the virtual detection device;

step 508, respectively initiating access to the at least one network device by using the IP address of the virtual detection device and the IP addresses respectively corresponding to the at least one network device, determining the target vlan as the detected vlan after initiating access to the at least one network device, and returning to step 502.

For the first case, for example, it can be known from the networking information that 10 hosts belong to different VLANs, where hosts 1 to 3 belong to VLAN1, hosts 4 to 6 belong to VLAN2, and hosts 7 to 10 belong to VLAN 3. Firstly, determining the VLAN1 as a target VLAN, determining the network devices belonging to the VLAN1 as hosts 1-3, determining the IP addresses of the hosts 1-3, allocating the IP addresses belonging to the VLAN1 to the virtual network devices, and at the moment, the virtual network devices and the hosts 1-3 belong to the same VLAN1, so that the virtual network devices can respectively initiate access to the hosts 1-3, and the states of the hosts 1-3 can be determined according to access results. Then, the processing method after determining VLAN2 as a target VLAN and determining VLAN3 as a target VLAN, and determining VLANs 2 and 3 as target VLANs is the same as that of VLAN 1. And finally, obtaining access results corresponding to the hosts 1-10 respectively.

It should be noted that, in step 502, it may be determined whether there is any undetected virtual local area network in the at least one virtual local area network by means of an identifier or the like. For example, the detected virtual local area networks are marked with special identifiers, and the virtual local area network which is not marked with the identifier in the at least one virtual local area network is determined as the undetected virtual local area network. For another example, it may be determined by a packet format, before initiating access to any network device in the VLAN, add the codes of the VLANs to a packet, for example, add VLAN1, VLAN2, and VLAN3 to the same packet, where the VLANs in the packet are all undetected VLANs, randomly take out a VLAN from the packet, and use the VLAN as a target VLAN until the packet does not include the VLAN.

The virtual detection equipment is created to detect the plurality of network equipment in the first condition, so that the virtual detection equipment is convenient to manage, and the detection cost is low.

In case two, the plurality of network devices correspond to at least two virtual local area networks, and the at least two virtual detection devices correspond to the at least two virtual local area networks one to one.

Referring to fig. 6, the step 104 of initiating access to the plurality of network devices by using the virtual detection device may include:

step 600, determining at least one network device belonging to a target virtual local area network of the at least two virtual local area networks, and IP addresses corresponding to the at least one network device respectively.

Step 602, allocating an IP address belonging to the target virtual local area network to the target virtual detection device corresponding to the target virtual local area network, and respectively initiating access to the at least one network device by using the IP address of the target virtual detection device and the IP addresses respectively corresponding to the at least one network device.

For the second case, for example, it can be known from the networking information that 10 hosts belong to different VLANs, where hosts 1 to 3 belong to VLAN1, hosts 4 to 6 belong to VLAN2, and hosts 7 to 10 belong to VLAN 3. Then 3 virtual inspection devices are created, respectively virtual inspection device a, virtual inspection device B, virtual inspection device C, where virtual inspection device a corresponds to VLAN1, virtual inspection device B corresponds to VLAN2, and virtual inspection device C corresponds to VLAN 3. Since the same operation is performed for each of VLANs 1 to 3, VLAN1 will be described as an example. The network equipment belonging to the VLAN1 is the host computers 1-3, the IP addresses of the host computers 1-3 are obtained, then the IP addresses belonging to the VLAN1 are distributed to the virtual detection equipment A, the virtual detection equipment A is used for respectively initiating access to the host computers 1-3, and therefore the access results of the host computers 1-3 can be obtained.

By creating at least two virtual detection devices in the second case, the at least two virtual detection devices correspond to the at least two virtual local area networks one to one, and each virtual detection device is used for detecting the network device in the corresponding virtual local area network, so that the detection efficiency can be improved.

It should be noted that, regardless of the first or second case, the manner of acquiring the IP address of the network device may be an IP address configured when networking information is configured for each network device in the simulated network topology when the simulated network topology is generated, and then the IP address of each network device is directly acquired according to the networking information; or the IP address may be obtained from the switch after networking.

In an embodiment of the present invention, the determining the state of each network device according to the access result in step 104 may include: and determining the state of the network equipment corresponding to the access result of successful access initiation as online, and determining the state of the network equipment corresponding to the access result of failed access initiation as offline.

In an embodiment of the present invention, after determining the states of the network devices, the virtual detection device may send the states of the network devices to a detection platform (the detection platform may be a platform end that creates the virtual detection device and initiates a detection instruction to the virtual inspection device, so that the virtual detection device completes the detection process according to the detection instruction), and the detection platform may automatically fill the states of the network devices into encapsulation information of device encapsulations corresponding to the network devices in the simulated network topology, so that a user may view the states of the corresponding network devices according to the encapsulation information of the device encapsulations.

In an embodiment of the present invention, the manner of initiating access includes: at least one of a ping mode, a web server mode, a TFTP mode and a ssh remote login mode.

The virtual detection device initiates an access to the host 1, and the manner of initiating the access is described as a ping manner. The virtual detection equipment sends a ping packet to the host 1, if the host 1 returns information aiming at the ping packet, the successful access is indicated, and the host 1 is on line; if host 1 does not react, this indicates that the initiation of access failed and host 1 goes offline.

Preferably, the maximum access frequency may be set when initiating access, for example, the maximum access frequency is set to 3 times, and if no response is found when initiating access to the same network device for 3 times, it is determined that the network device is offline, so that accuracy of an access result can be improved.

With respect to step 106, it is determined whether the entity network topology is successfully networked according to the status of each network device.

And if not, determining that the entity network topology fails to be networked according to the networking scheme. For example, in the hosts 1 to 10, the states of the hosts 1 to 9 are all online, and the state of the host 10 is offline, indicating that networking fails.

In an embodiment of the present invention, the types of the network devices may include: a physical network device and/or a virtual network device.

The physical network topology may be formed by only physical network devices, may be formed by only virtual network devices, or may include both physical network devices and virtual network devices.
