Description
Technical Field
The invention relates to the field of wireless base stations, in particular to a method for balancing the downloading load of a virtualized network management file and a network management server.
Background
The traditional base station has large and complete network management functions, and the number of the managed base stations is large. Although the network management software generally runs on a high-performance server, when a plurality of base stations request services at the same time, especially the duration is long, the resource consumption is large, for example, a large number of files are downloaded at the same time (for example, version files), which may cause the CPU (central processing Unit) of the network management server to be high, and other reasonable requests are rejected.
Version management is a very important function of network management, and mainly includes operations of downloading, upgrading, activating, returning and the like of versions, and belongs to an important module in file management. A large and medium-sized city generally deploys thousands of base stations, and when the version of the whole network is upgraded, the base stations download the version from a version server of a network manager (generally, using an FTP (File Transfer Protocol). When a plurality of base stations upgrade versions at the same time, the network management version server reads and writes the disk and the forwarding data rate is accelerated, so that the CPU of the network management is driven to be high, an alarm is generated, and normal requests of other base stations are rejected.
In order to protect the normal use of the network management function, the network management is generally designed to limit the number of connections downloaded by the base station, and each connection is limited in speed, so that the upgrade time of the whole network element base station is very long, and the user experience is poor. Meanwhile, the performances of different hardware servers are different, and the limit of software on the number of connections is fixed, which may cause that some servers have a relatively hard performance when fully connected, and other servers have residual resources. Whether some dynamic calling of resources can be realized is one of the difficult problems to be solved by the traditional network management version management, but none of the problems has a solution disclosed at present.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be further described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments of the present application may be arbitrarily combined with each other without conflict.
Example 1
The inventor of the present application finds that unified orchestration (Orchetrator) of hardware virtualization management, cloud management, and business management is mentioned in the NFV (network Function virtualization) architecture. The base station of the next generation must also meet the standard of virtualization, and the similar general-purpose devices stored in the core computer room, such as the network manager, are required to be virtualized earlier. Therefore, the inventor proposes that the network management system can directly run on a high-performance general server, and only needs to add a layer of virtualization (such as installing virtualization or container technologies like Openstack or Docker), and independently run the file management (including version management) function on different virtual machines, thereby improving the file management capability of the network management system and reasonably utilizing hardware resources. Based on the above thought, this embodiment provides a method for load balancing of file downloading for virtualized network management, which mainly includes the following steps:
step 100, a network management server pre-configures an independent file management virtual machine;
in this step, the independent file management virtual machines preconfigured by the network management server include one or more virtual machines, wherein each virtual machine has a different IP address when a plurality of virtual machines are included.
In addition, the file management referred to in the present embodiment includes version management.
Step 200, in the process that the network management server provides the file management service for the base station, the network management server monitors the hardware resources of the whole network management server, if the network management server monitors that the current hardware resources are sufficient, step 300 is executed, and if the network management server monitors that the current hardware resources are deficient, step 400 is executed;
in this step, the process of the network management server monitoring the hardware resources of the whole network management server is as follows:
the network management server monitors the utilization rate of the current hardware resource;
if the utilization rate of the monitored current hardware resource is less than the maximum threshold value, determining that the current hardware resource is sufficient;
and if the utilization rate of the monitored current hardware resource reaches or exceeds the maximum threshold value, determining that the current hardware resource is deficient.
The maximum threshold value comprises any one or more of a preset CPU (central processing unit) running rate maximum threshold value, a memory capacity maximum threshold value and a current network bandwidth maximum threshold value.
Step 300, scheduling and creating a new file management virtual machine, increasing the speed and the connection number of file downloading, and ending the process;
step 400, stopping starting new service, migrating the existing connection to other file management virtual machines, deleting the idle file management virtual machine, and ending the process.
It should be noted that, when the system is powered on again or the network management server completes the file management service for the base station, the number of the file management virtual machines can be restored to the initial number of the file management virtual machines.
Example 2
The present embodiment provides a network management server, which mainly splits a core function of a network management system into a plurality of independent modules, and separates modules with high common management and resource consumption. The modules with high resource consumption can be operated independently and deployed in the cloud, and the rest modules are operated on the rest Virtual Machines (VMs), and the principle is shown in fig. 1.
Specifically, the network management server mainly comprises the following modules.
The file management module runs on an independent virtual machine;
the cloud end adopts different virtualization technologies, each file management module runs on a virtual machine, and the running environment of the virtual machine can be based on virtualization or container technologies such as Openstack and Docker.
And powering on the network management system, generating a default number of virtual machines according to the previous configuration file or configuration parameter, and operating default specification parameters such as the maximum connection number of file downloading and the like by each virtual machine.
And the dynamic monitoring module monitors available hardware resources, and if the current hardware resources are sufficient, more virtual machines are scheduled and created to the module with more resource consumption (namely the file management module), so that the processing speed of the module with higher current load is accelerated. If the utilization rate of the hardware resources reaches the threshold value (namely the hardware resources are deficient), stopping starting new service or rejecting a new service request, migrating the existing connections to the virtual machines as few as possible, and deleting the idle virtual machines. When determining whether the hardware resources are deficient, the determination may be performed according to the utilization rate of the hardware resources, and specifically, the utilization rate of the hardware resources may include a maximum utilization rate of a CPU, a maximum threshold value of a memory capacity, a maximum threshold value of a network bandwidth, a maximum threshold value of a memory capacity, and the like.
And after the high resource consumption request is finished, the dynamic monitoring module restores the configuration of each virtual machine to a default state.
In addition, a load balancing module may be added to the network management system, and the whole system architecture is shown in fig. 2. The dynamic monitoring module monitors the running performance state of the network manager, and the load balancing module dynamically schedules newly accessed users to access appropriate virtual machines according to the current resource access condition.
It is noted that the high resource consuming modules in the present application include, but are not limited to, file management, and the manner of consuming the high resource consuming modules is also within the scope of the present application.
The application scene is not limited to the application of the base station, and other ways of placing the resource high-load request in the cloud are also within the protection range of the application.
The following describes a specific process of the above network management server to implement file management with reference to the accompanying drawings, where the process is shown in fig. 3, and includes the following steps:
301. the network management software independently splits out the high resource consumption function, such as the version management function.
302. The split file management function (such as version management function) runs on an independent virtual machine, and the rest functions (such as network management system) run on other virtual machines.
The split file management function can run on one or more virtual machines, and each virtual machine has a different ip (internet protocol) address.
For example, 2 file management virtual machines can be configured by default, the IP addresses are 192.168.1.2/24 and 192.168.1.3/24 respectively, and the virtual machine IP operated by the rest modules of the network management is 192.168.1.1/24. The maximum number of connections supported by each virtual machine for file management is 96.
303. The network manager sends down a version download (such as version update) command to the base station. The base station requests the network management to send down the version, and the network management load balancing module distributes the optimal URL to the base station according to the running conditions of the file management modules on different virtual machines at present, or creates more file management virtual machines to receive more connections;
it is assumed. And the load balancing module distributes the file management virtual machine IP with lighter load according to the current base station operation condition, and the file management virtual machine IP such as 192.168.1.2/24 is returned to the base station. Preferably, the base station may simultaneously return the progress of the file download.
304. The network management dynamically monitors the performance of the current virtual machine operation (namely the hardware resource utilization rate of the whole network management system);
305. and judging whether the utilization rate of the hardware resources reaches a threshold value, if so, entering a step 306, otherwise, scheduling and creating more file management virtual machines, increasing the file downloading speed and the connection number, and returning to the step 303.
The threshold includes a maximum utilization rate of the CPU, a maximum threshold of the memory capacity, a maximum threshold of the current network bandwidth, and the like.
Assuming that the maximum threshold of the hardware resource is 80% of the CPU running rate, when the CPU running rate is lower than 60%, 2 file management virtual machines can be created, corresponding to the IPs 192.168.1.4/24 and 192.168.1.5/24, and more versions are simultaneously issued to the base station. And if the CPU running rate is higher than 80%, stopping sending the version, migrating the connection of the other file management virtual machines to the 192.168.1.2/24 virtual machine, and deleting the corresponding virtual machine when the other file management virtual machines are not connected.
306. Stopping starting new service or refusing new base station file downloading request, transferring existing connection to virtual machines as few as possible, and deleting idle file management virtual machines.
307. After the file is updated and downloaded, the dynamic monitoring module restores the configuration of each virtual machine to a default state.
That is, the dynamic monitoring module restores the file management virtual machines to default 2, the number of each connection is 96, and the corresponding IP addresses are 192.168.1.2/24 and 192.168.1.3/24 respectively.
It will be understood by those skilled in the art that all or part of the steps of the above methods may be implemented by instructing the relevant hardware through a program, and the program may be stored in a computer readable storage medium, such as a read-only memory, a magnetic or optical disk, and the like. Alternatively, all or part of the steps of the above embodiments may be implemented using one or more integrated circuits. Accordingly, each module/unit in the above embodiments may be implemented in the form of hardware, and may also be implemented in the form of a software functional module. The present application is not limited to any specific form of hardware or software combination.
The above description is only a preferred example of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
