Based on the above hardware structure, the present invention provides various embodiments of the dynamic address allocation service configuration method.
Referring to fig. 2, a first embodiment of a dynamic address assignment service configuration method of the present invention provides a dynamic address assignment service configuration method, it being noted that although a logical order is shown in the flow chart, in some cases, the steps shown or described may be performed in an order different than here. The dynamic address allocation service configuration method comprises the following steps:
step S1, when the current wireless router is in the target working mode, detecting the WAN port state of the current wireless router;
most of the existing wireless routers support the WDS function, and when the WDS function is started, the wireless router can be in bridge connection with other wireless routers which start the WDS function, so that wireless signals can be expanded. The AP + WDS mode of the wireless router means that the wireless router can be used as a wireless Access Point (AP) to provide a normal wireless routing function, and can also be used as a bridging device of a WDS (wireless distributed system), thereby expanding wireless signals and improving coverage. The dynamic address allocation service of the wireless router automatically allocates an IP address for the user terminal connected with the wireless router, so that the user terminal can surf the internet normally.
In the AP + WDS networking, a plurality of wireless routers are provided, wherein only one wireless router is used as an exit node to communicate with an external network, and the rest wireless routers are internal nodes and are bridging devices. The wireless router serving as the exit node needs to start a dynamic address allocation service to allocate an IP address to a connected user terminal, while the wireless router serving as the internal node cannot start the dynamic address allocation service, otherwise, when the IP address acquired by the user terminal is allocated by the internal node, the user terminal is abnormally on line. It should be guaranteed that the internal nodes in the AP + WDS network turn off the dynamic address allocation service when the WDS bridge connection is normal.
In order to implement that the wireless router as the internal node automatically turns off the dynamic address allocation service when the bridge connection is normal, in this embodiment, when the wireless router is in the target operating mode, the current wireless router starts to detect the WAN port state of the wide area network. The target operating mode may be an AP + WDS mode of the wireless router, or may be another operating mode equivalent to the AP + WDS mode. Since the egress node in the AP + WDS networking communicates with the external network through the WAN port, when the WAN port state of the wireless router is the connected state, it can be determined that the wireless router is used as the egress node in the networking. Therefore, when the wireless router detects that the WAN port state is connected, the current wireless router is determined to be the exit node, and at the moment, if the dynamic address allocation service of the current wireless router is in the closed state, the dynamic address allocation service of the current wireless router can be started.
Step S2, if the WAN port state is detected to be an unconnected state, detecting whether the current wireless router is in bridge connection with other wireless routers;
and if the current wireless router detects that the WAN port state is an unconnected state, detecting whether the current wireless router is in bridge connection with other wireless routers. If the current wireless router detects that the WAN port state is the unconnected state, the current wireless router is not an exit node which directly communicates with an external network but an internal node, and at the moment, the current wireless router detects whether the current wireless router is in bridge connection with other wireless routers or not so as to determine whether the current wireless router can surf the internet through other wireless routers or not.
Step S3, if it is detected that the current wireless router is connected to another wireless router in a bridge manner, the dynamic address allocation service of the current wireless router is set to be in a closed state.
And if the current wireless router detects that the WAN port state is an unconnected state and the current wireless router detects that the wireless router is in bridge connection with other wireless routers, setting the dynamic address allocation service of the current router to be in a closed state. Specifically, if the dynamic address allocation service of the current wireless router is originally in the closed state, the closed state is maintained, and if the dynamic address allocation service of the current wireless router is originally in the open state, the dynamic address allocation service is closed. It should be noted that, the WAN port of the wireless router is not connected, but is connected to another wireless router in a bridging manner, which indicates that the wireless router is an internal node that can surf the internet through another wireless router, and at this time, the dynamic address allocation service of the wireless router should be turned off, so as to ensure that the user terminal does not surf the internet abnormally due to acquiring the IP address allocated by the wireless router. Specifically, the wireless router may turn off the dynamic address assignment service by turning off the udhcpd process, but may also turn off the dynamic address assignment service by other feasible manners.
Further, if the current wireless router is not in bridge connection with other wireless routers even when detecting that the WAN port is not connected, the wireless router may set the dynamic address allocation service to be in an on state at this time.
In the embodiment, when the current wireless router is in the target working mode, the current state of the router WAN port is detected; if the WAN port state is detected to be the unconnected state, detecting whether the current wireless router is in bridge connection with other wireless routers; if the bridge connection between the current wireless router and other wireless routers is detected, the dynamic address allocation service of the current router is set to be in a closed state, and the automatic closing of the dynamic address allocation service by the internal node with normal WDS bridge connection in the AP + WDS networking is realized, so that the dynamic address allocation service of the internal node in the AP + WDS networking does not need to be configured manually, and the problem of abnormal internet access of the user terminal in the AP + WDS networking is solved.
Further, referring to fig. 3, based on the first embodiment, a second embodiment of the dynamic address allocation service configuration method of the present invention provides a dynamic address allocation service configuration method. In this embodiment, after step S1, the method further includes:
step S4, if it is detected that the WAN port state is the connected state, setting the dynamic address allocation service of the current wireless router to an open state.
The current wireless router detects the state of the WAN port of the current wireless router, and if the WAN port is detected to be connected, the dynamic address allocation service of the current wireless router is set to be in an open state. If the WAN port of the wireless router is connected, it indicates that the wireless router is an egress node for communicating with an external network, and at this time, the dynamic address allocation service of the wireless router should be started, and the router allocates IP addresses to the user terminal and the internal node. The wireless router may initiate the dynamic address assignment service by initiating the udhcpd process, or may initiate the dynamic address assignment service by other feasible means. Specifically, after the wireless router is started, if the wireless router is in a target working mode, the state of a WAN port starts to be detected, if the state of the WAN port is detected to be unconnected, whether the current router starts a dynamic address allocation service is detected, if the current router is not started, the dynamic address allocation service is started, and if the dynamic address allocation service is originally in a started state, the start state of the dynamic address allocation service is maintained. If the wireless router detects that the WAN port state is connected to the non-connected state, the WDS connection state is detected, if the WDS connection is detected to be normal, whether the dynamic address allocation service is started or not is detected, if the WDS connection is not started, the closing state of the dynamic address allocation service is continuously kept, and if the dynamic address allocation service is started, the dynamic address allocation service is closed.
In this embodiment, when the wireless router detects that the WAN port is connected, the dynamic address allocation service of the current wireless router is set to the on state, so that the egress node in the AP + WDS networking automatically turns on the dynamic address allocation service, and thus the dynamic address allocation service of the egress node in the AP + WDS networking does not need to be manually configured.
Further, based on the first or second embodiment, a third embodiment of the dynamic address allocation service configuration method of the present invention provides a dynamic address allocation service configuration method. In this embodiment, after step S2, the method further includes:
step S5, if it is detected that the current wireless router is not in bridge connection with another wireless router, the dynamic address allocation service of the current wireless router is set to be in an open state.
And if the current wireless router detects that the WAN port state is not connected and detects that the wireless router is not in bridge connection with other wireless routers, setting the dynamic address allocation service of the current wireless router to be in an open state. When the wireless router detects that the state of the WAN port of the wireless router is not connected and is not in bridge connection with other wireless routers, the wireless router can not communicate with an external network and can not surf the internet through other wireless routers, and at the moment, the wireless router can start dynamic address allocation service so that a user terminal connected with the wireless router can perform network configuration on the wireless router. It should be noted that, when detecting that the WAN port is disconnected, the wireless router detects whether the dynamic address allocation service is turned on if detecting that the wireless router is successfully connected to another wireless router in a bridge connection manner, and if so, turns off the dynamic address allocation service, and if not, maintains the turned-off state of the dynamic address allocation service. Under the condition that the wireless router detects that the WAN port state is not connected, if the wireless router detects that the wireless router is not successfully in bridge connection with other wireless routers, whether the dynamic address allocation service is started or not is detected, if the wireless router is started, the starting state of the dynamic address allocation service is kept, and if the wireless router is not started, the dynamic address allocation service is started.
Further, based on the first, second or third embodiments, a fourth embodiment of the dynamic address allocation service configuration method of the present invention provides a dynamic address allocation service configuration method. In the present embodiment, step S1 includes:
step S101, detecting whether a WAN port of a current wireless router is inserted into a network cable;
when the wireless router is in the AP + WDS mode, the state of the WAN port of the current wireless router is detected, and the detection method can be realized by detecting whether the WAN port is plugged into a network cable or not.
Step S102, if the WAN port is detected to be inserted into a network cable, determining that the current state of the WAN port of the wireless router is a connected state;
the wireless router is provided with a WAN physical interface inserted into the network cable, if the wireless router detects that the WAN port is inserted into the network cable, the wireless router is used as an exit node for communicating with an external network, and at the moment, the wireless router determines that the WAN port is connected. At this time, the wireless router is used as an egress node for communicating with an external network, and if the dynamic address assignment service is in an off state, the dynamic address assignment service is set to an on state.
And step S103, if the WAN port is detected not to be plugged into a network cable, determining that the current state of the WAN port of the wireless router is an unconnected state.
If the wireless router detects that the WAN port is not plugged into the network cable, the wireless router can not communicate with the external network through the network cable, and if the wireless router can only communicate with the external network by plugging the network cable, the wireless router can determine that the state of the WAN port is in an unconnected state, namely if the wireless router detects that the WAN port is not plugged into the network cable, the wireless router is determined not to be an exit node for communicating with the external network. At this time, the wireless router, as an internal node, detects whether to bridge with other wireless routers, and determines whether to start a dynamic address allocation service according to the detection result.
Further, step S1 includes:
step S111, detecting whether the current wireless router obtains an IP address through a WAN port;
if the wireless router can communicate with the external network in a wireless relay mode, that is, the wireless router does not necessarily communicate with the external network in a mode of inserting a network cable into the WAN physical interface, the WAN port state can be detected by detecting whether the IP address is acquired through the WAN port. The wireless router can acquire the IP address through a WAN port in a wireless relay mode or a network cable insertion mode through a WAN physical interface.
Step S112, if the IP address is acquired through the WAN port, determining that the WAN port is normally connected;
if the wireless router detects that the correct IP address is obtained from the external network through the WAN port, the wireless router can be determined to normally communicate with the external network, and the state of the WAN port is connected. At this point the wireless router is determined to be an egress node.
Step S113, if it is detected that the IP address is not acquired through the WAN port, it is determined that the WAN port is not connected.
And if the IP address is detected not to be acquired through the WAN port, determining that the state of the WAN port is unconnected. The above-described method of determining the WAN port state by detecting whether the WAN port is plugged in a network cable and the method of determining the WAN port state by detecting whether the IP address is acquired through the WAN port may be applied either selectively or in combination. The combined application mode may be that after the wireless router detects that the IP address is obtained through the WAN port, the state of the WAN port is determined to be connected, if it is detected that the IP address is not obtained through the WAN port, it may be detected whether the WAN port is plugged in the network cable, if the network cable is plugged in, it may be determined that the state of the WAN port is connected, and if the network cable is not plugged in, it may be determined that the state of the WAN port is unconnected.
Further, step S1 includes:
step S121, detecting whether the domain name resolution of the current wireless router is normal;
because the wireless router may not normally communicate with the external network even if the WAN port is plugged into the network or acquires the IP address, normal communication with the external network may be used as a premise for determining that the wireless router is an egress node, that is, if the wireless router normally communicates with the external network, it is determined that the WAN port state of the wireless router is connected, it is determined that the wireless router is the egress node, and if the wireless router cannot normally communicate with the external network, it is determined that the WAN port state of the wireless router is unconnected. And whether the wireless router normally communicates with an external network is judged by detecting whether the domain name resolution of the current wireless router is normal.
Step S122, if the domain name resolution is detected to be normal, determining that the WAN port state of the current wireless router is a connected state;
if the wireless router detects that the DNS domain name resolution is normal, the wireless router can normally communicate with an external network, and the wireless router determines that the WAN port state is connected.
Step S123, if the domain name resolution is detected to be abnormal, determining that the current WAN port state of the wireless router is an unconnected state.
If the wireless router detects that the DNS domain name resolution is abnormal, the wireless router can not normally communicate with an external network, and the wireless router determines that the WAN port state is unconnected. It should be noted that, the method of determining the WAN port state by detecting whether DNS domain name resolution is normal, the method of determining the WAN port state by detecting whether a WAN port is plugged in a network cable, and the method of determining the WAN port state by detecting whether an IP address is acquired through the WAN port may be applied either selectively or in combination. The mode of combined application can be as follows: when the wireless router detects that DNS domain name resolution is normal, the WAN port connection can be determined to be normal; if the DNS domain name resolution is detected to be abnormal, after the IP address is detected to be obtained through the WAN port, the WAN port can be determined to be normally connected, if the IP address is detected not to be obtained through the WAN port, whether a network cable is inserted into the WAN port or not can be detected, if the network cable is inserted, the WAN port can be determined to be normally connected, and if the network cable is not inserted, the WAN port is determined to be not connected.
Further, based on the first, second, third or fourth embodiments, a fifth embodiment of the dynamic address allocation service configuration method according to the present invention provides a dynamic address allocation service configuration method. In this embodiment, the step of detecting the WDS connection status includes:
step S201, counting the number of frames of beacon frames sent by other wireless routers and received within a preset time;
and under the condition that the wireless router detects that the WAN port is not connected, detecting whether the current wireless router is in bridge connection with other wireless routers. The wireless router can determine whether to bridge with other wireless routers by counting the number of frames of beacon frames sent by other wireless routers received within a preset time period. The wireless router broadcasts a Beacon frame (Beacon frame) to other wireless routers in the AP + WDS mesh, and the Beacon frame has its own MAC address (hardware address) written therein. The wireless router counts the number of frames of beacon frames sent by other wireless routers received within a preset time, wherein the preset time can be set according to specific needs, and if the preset time is set to 10 seconds, the wireless router counts every 10 seconds. The wireless router obtains the MAC address by analyzing the beacon frame, and can determine which other wireless router sends the beacon frame. And the wireless routers respectively count beacon frames sent from different other wireless routers within a preset time length. If the wireless router 1 counts that 10 frames of beacon frames written with the MAC address of the router 2 are received within 10 seconds, 2 frames of beacon frames written with the MAC address of the router 3 are received.
Step S202, if the number of beacon frames sent by the other wireless routers received within the preset time length is greater than a preset frame number, determining that the WDS connection is normal;
and if the number of beacon frame frames sent by other wireless routers and received by the wireless router in the preset time duration is greater than the preset frame number, determining the bridging connection. The preset frame number can be set according to specific conditions. If the wireless router is set to receive 1 beacon frame sent by other wireless routers within 10 seconds, the wireless router is determined to be in bridge connection with other wireless routers. As a specific example, it is counted that the router 1 receives 10 frames of beacon frames written with the MAC address of the router 2 within 10 seconds, and does not receive beacon frames written with the MAC address of the router 3 and beacon frames written with the MAC address of the router 4, then the router 1 determines that the router 1 is in bridge connection with the router 2, but is not connected with the routers 3 and 4, and at this time, it is determined that the router 1 is in bridge connection with other routers in the AP + WDS network.
Step S203, if the number of beacon frames sent by the other wireless routers received in the preset time period is not greater than the preset number of frames, determining that the WDS is not connected.
And if the number of beacon frame frames sent by other wireless routers and received by the wireless router in the preset time duration is not more than the preset frame number, the wireless router is not in bridge connection with other wireless routers. And if the wireless router does not receive 1 beacon frame from other wireless routers within the preset time, determining that the wireless router is not in bridge connection with other wireless routers.
Further, whether the wireless router is in bridge connection with other wireless routers can also be determined by counting the data packets received by the wireless router, or by other feasible ways.
In this embodiment, the WDS connection state of the wireless router is determined by counting the number of beacon frames sent by other wireless routers received within a preset time period, and then the WDS connection state configures a dynamic address allocation service, so that the function of automatically configuring the dynamic address allocation service for the wireless router in the AP + WDS network is achieved.
