Drawings
The foregoing and/or additional aspects and advantages of the invention will become apparent and may be better understood from the following description of embodiments taken in conjunction with the accompanying drawings in which:
fig. 1 is a flow chart of a router link automatic switching method in an embodiment of the invention.
Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.
In the description of the present invention, unless explicitly defined otherwise, terms such as arrangement, installation, connection, etc. should be construed broadly and the specific meaning of the terms in the present invention can be reasonably determined by a person skilled in the art in combination with the specific contents of the technical scheme.
Referring to fig. 1, a router link automatic switching method includes the steps of:
s100, setting the router into a bridging mode and configuring corresponding bridging parameters according to the upper and lower bridging devices, wherein the bridging parameters comprise IP and MAC addresses of the upper bridging devices and IP and MAC addresses of the lower bridging devices.
S200, configuring a wired wan module of the router as a priority link and configuring a 5G module as a standby link;
s300, initializing a 5G module and a wired wan module after power-on, acquiring user configuration wan parameters, reading a priority working mode of a router by a process, modifying if the router is not wired in a wired bridge mode, and setting the router to be in a wired wan priority mode for saving communication cost, wherein the cost of a wired network is usually fixed, and the 5G communication cost is charged according to flow, so that the wired network is used for data transmission as much as possible. Then the router detects whether the communication state of the wired network is normal or not through a bridge mode wan state detection method, and the specific steps are as follows:
s301, a group of public network IPs are selected, the number of the public network IPs in the embodiment is 3, public network IPs which are not missed by a wired line and are less time-consuming are required to be selected, because the wan port of the router in the bridge mode cannot be configured with the IPs, the router needs to be configured with the IP and the MAC address of the lower bridge equipment in the step S100, and therefore the router can disguise the ICMP packet by taking the IP and the MAC address of the lower bridge equipment as the source IP address and the MAC address and initiate a ping message request to the external network IP through a wan interface.
S302, capturing a response packet of the wan interface through a packet capturing module, wherein the packet capturing module can adopt a PCAP module or an NDPI module, in the embodiment, the PCAP module is adopted, and if the response packet is captured in 2S after a ping message request is initiated, the wired network communication state is considered to be normal; if no response is obtained by all the external network IPs within 2S, it is considered abnormal.
If the communication state of the wired network is normal, the router continues to transmit data through a wired wan mode and continuously transmits ping message requests at intervals, and if the communication state is abnormal, the router switches to a 5G mode to transmit data, so that the smoothness of data transmission is maintained.
And S400, the router detects whether the communication state of the wired wan module is normal or not in a timing mode through the bridge mode wan state detection method which is the same as that of the steps S301-302, the timing time is 2S, if the communication state is normal, the router is immediately switched to the wired wan mode, and if the communication state is abnormal, the router continues to operate in the 5G mode, so that the generation of 5G communication cost can be reduced as much as possible, and the communication cost is saved.
The invention also relates to a dual-frequency router, which comprises a router body, wherein the router body performs switching between a 5G mode and a wired wan mode through the router link automatic switching method.
In summary, the embodiment of the invention can insert the 5G gateway equipment node under the condition of keeping the original network architecture unchanged, thereby realizing the wired transparent transmission of the data; when in use, because the 5G charge is relatively high at present and operators charge according to the flow, users hope that all the flow is forwarded through the wire wan under the condition that the wire is normal, but the wire can sometimes fail, so that the users cannot normally access the network, therefore, a 5G mode is used as a backup link, the 5G communication network is switched to after the wire is interrupted due to failure, but the manual switching can be insufficiently timely processed and the maintenance cost is improved if the manual switching is performed manually, and the like, therefore, the routing gateway sends a network detection packet through a bridge mode wan state detection method, automatically detects the network communication state of the wire wan in real time, automatically switches to the 5G network when the wire wan is abnormal, and automatically returns to the network state of the wire wan after the wire wan is out of failure, the network access mode is automatically completed without manual operation in the communication process, thereby achieving the effect of quickly enabling the network to recover to be normal, and improving the efficiency of the user to use the network.
The embodiment of the invention enables the router to work in the bridging mode, can realize data transparent transmission, does not need to change the network architecture when the router is accessed to bridging equipment, does not need to change the original equipment on the network, and saves manpower. After the wired network fails, the router can be automatically switched to a 5G mode to ensure the normal data communication, and in the 5G mode, the router detects the state of the wired network in real time through a bridge mode wan state detection method, and after the wired network is recovered, the router is automatically switched back to a wan mode, so that the switching of a network access mode can be automatically completed, the network can be quickly recovered without manual operation, the network utilization efficiency of a user is improved, and the communication cost is maximally saved.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present invention.
