[0067] The exemplary embodiments of the present application will be described in more detail below in conjunction with the accompanying drawings in the embodiments of the present application. Although the accompanying drawings show exemplary embodiments of the present application, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0068] The goal of network protocols is to generate and update routing information used to guide packet forwarding within the network. Depending on the characteristics of channel transmission, different routing protocols are often deployed for broadband and narrowband networks. In related technologies, routing protocols primarily used for broadband links are OSPF and RIP, while routing protocols primarily used for narrowband channels are OLSR and AODV. Currently, achieving consistent routing protocols for both broadband and narrowband channels remains difficult. Furthermore, the convergence of broadband and narrowband channel routing relies heavily on the deployment of additional equipment for convergence, resulting in high costs and relatively complex networking.

[0069] In view of the above problems, the embodiments of the present application provide a broadband and narrow routing fusion system, method, and product to solve the above problems such as the difficulties of broadband and narrow routing fusion. The following, in conjunction with the accompanying drawings, describes in detail a broadband and narrow routing fusion system provided by the embodiments of the present application through some embodiments and their application scenarios.

[0070] The first aspect of the embodiment of the present application provides a broadband and narrow routing fusion system, referring to Figure 1 , Figure 1 A schematic diagram of the structure of a broadband and narrowband routing fusion system provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the system includes: a broadband routing module, a narrowband routing module, a routing fusion module and a routing management module;

[0071] The broadband routing module is used to run the broadband routing protocol on demand according to the type of wired channel connected to the device interface, receive broadband routing protocol data, and send it to the routing fusion module;

[0072] The narrowband routing module is used to run the narrowband routing protocol on demand according to the type of wireless channel connected to the device interface, receive narrowband routing protocol data, and send it to the routing fusion module; the narrowband routing module ensures that there are no routing loops by controlling the order of routing updates and deletions;

[0073] The routing fusion module is configured to receive the broadband routing protocol data and the narrowband routing protocol data through a unified interface format, determine an optimal route therefrom, and send the optimal route to the routing management module;

[0074] The routing management module is used to store, search and issue routing data according to the received optimal route.

[0075] Reference Figure 2 , Figure 2 A schematic diagram comparing the routing fusion of a traditional solution and this solution is shown in FIG. Figure 2 As shown, in the related art, in order to realize the fusion of broadband routing and narrowband routing, it is necessary to set up an additional routing fusion device on the basis of the routing switching device, such as Figure 2 As shown on the left, one of the two devices is used to execute the broadband routing protocol to receive the broadband routing protocol data sent by the wired channel, and the other is used to execute the narrowband routing protocol to receive the narrowband routing protocol data sent by the wireless channel. Through the established routing fusion device, the collected narrowband routing protocol data is sent to the routing switching device, and the broadband routing protocol collected by the routing switching device is accepted. According to the above scheme, the routing data needs to be forwarded between the routing switching device and the routing fusion device to achieve fusion, and the additional deployment of routing fusion devices will lead to increased costs and complex networking. According to the broadband and narrow routing fusion system proposed in this application, Figure 2 As shown on the right, it is possible to directly receive routing data from different sources based on existing routing switching equipment through the deployed broadband routing modules and narrowband routing modules, and then use the routing fusion module to realize the fusion processing of routing data, and use the routing management module to realize the distribution of routing data. The data exchange function of wired and wireless channels can be completed in one device, solving the problem that the fusion function in traditional methods requires the deployment of additional independent equipment, thereby reducing the routing switching cost.

[0076] In this embodiment, the broadband routing module and the narrowband routing module serve as input modules of the routing fusion system, utilizing their respective interfaces to receive routing data from different sources. Specifically, the broadband routing module receives broadband routing protocol data, while the narrowband routing module receives narrowband routing protocol data. Furthermore, both modules can also receive user-defined routing data based on actual configuration.

[0077] As the core processing module of the routing fusion system, the routing fusion module prioritizes routing data (broadband routing protocol data and narrowband routing protocol data) with the same destination IP but different sources according to default rules or user-defined rules through a unified interface format, selects the optimal route, and realizes the automatic fusion and optimization of routes of different source types.

[0078] The ultimate goal of routing information is to realize the forwarding of data packets on the switching device. This embodiment uses the routing management module to store, search and send routing data according to the received optimal route. Specifically, the optimal route can be sent to the data exchange module (the optimal route is sent to the switching module of the switching device through a unified interface to generate routing table information), or the optimal route can be reported to other applications on demand (by defining a unified interface, the routing dynamic information is opened to users or upper-layer applications, which can be used for other functional modules such as data packetization and channel bandwidth data collection). The embodiment of the present application solves the problem that the fusion function in the traditional method requires the deployment of additional independent equipment through a system for automatic fusion of broadband and narrowband routing. The broadband routing module, narrowband routing module and routing fusion module in this embodiment can be directly deployed in the routing switching device, integrating the data exchange functions of wired and wireless channels into one device.

[0079] In a possible implementation, the routing fusion module is further configured to perform mutual penetration of routing data of different types and sources, including:

[0080] The routing fusion module sends the broadband routing protocol data to the narrowband routing module, and after receiving the broadband routing protocol data, the narrowband routing module spreads the data to the switching device through a wireless channel;

[0081] The routing fusion module sends the narrowband routing protocol data to the broadband routing module. After receiving the narrowband routing protocol data, the broadband routing module diffuses the data to the switching device through a wired channel.

[0082] In this embodiment, the narrowband routing module learns and diffuses routes through wireless channels. Specifically, after the device is started, the narrowband routing module runs the narrowband routing protocol as needed based on the channel type of the interface. This module learns remote routes (receives narrowband routing protocol data) by running the narrowband routing protocol and sends it to the routing fusion module. Simultaneously, the routing fusion module receives routes learned through wired channels (i.e., broadband routing protocol data) and diffuses them to remote switching devices through wireless channels, ensuring that every device in the network that contains a narrowband channel has the entire network's routes (broadband and narrowband routing).

[0083] The broadband routing module learns and diffuses routes through wired channels. Specifically, the broadband routing module runs the broadband routing protocol on demand based on the channel type to which the device interface is connected, learns remote routes through the broadband routing protocol (receives broadband routing protocol data), and sends this data to the routing fusion module. Furthermore, the broadband routing module can receive routes learned through wireless channels (i.e., narrowband routing protocol data) from the routing fusion module and diffuse them to remote switching devices through wired channels, enabling each device in the network with a wired channel to have full-network routes (both broadband and narrowband).

[0084] In one possible implementation, the broadband routing protocol data and / or the narrowband routing protocol data include at least: a routing source type, a routing destination IP address, routing outbound interface information, and a cost value. Specifically, the routing fusion module provides a unified interface format for receiving broadband and narrowband routes, including the routing source type, the routing destination IP address, the routing outbound interface, and the cost value.

[0085] In a possible implementation, determining the optimal route includes:

[0086] For the plurality of narrowband routing data and / or broadband routing data with the same routing destination IP, the routing fusion module determines the routing data with the shortest cost value as the optimal route; or

[0087] For the plurality of narrowband routing data and / or broadband routing data with the same routing destination IP, the routing fusion module performs priority sorting according to a preset rule and determines the routing data with the highest priority as the optimal route.

[0088] In this embodiment, for routes with the same destination IP but different sources, the route fusion module prioritizes them according to the default shortest cost value or user-defined rules (such as giving priority to fiber channels), selects the optimal route, and sends it to the route management module.

[0089] In a possible implementation, the routing management module generates a flow classification forwarding rule table according to preset service feature rules, wherein the preset service feature rules include: UDP port number, destination IP network segment;

[0090] The routing management module generates an openflow protocol message according to the routing table and the flow classification forwarding rule table, and sends it to the forwarding chip to execute forwarding of user data packets.

[0091] In this embodiment, the routing management module receives user-defined forwarding rules based on service characteristics (such as UDP port number and destination IP network segment) and generates a flow classification forwarding rule table. When the router receives an IP packet, it matches the destination IP address of the IP packet between the routing table and the flow classification forwarding rule table to obtain a corresponding routing entry. The router then forwards or sends the packet based on the outgoing interface or next hop information in the entry.

[0092] In a possible implementation, generating an OpenFlow protocol message based on the routing table and the flow classification forwarding rule table, and sending the message to the forwarding chip to forward the user data packet includes:

[0093] When the routing management module receives a forwarding request for user data, searching the flow classification forwarding rule table;

[0094] If a specified rule is found during the search, a search result is generated according to the specified rule;

[0095] If the specified rule cannot be found, searching the routing table according to the destination IP address to obtain the search result;

[0096] According to the outbound interface channel type of the search result, encapsulate the corresponding IP header to obtain the openflow protocol message;

[0097] The openflow protocol message is sent to the forwarding chip, and the forwarding chip forwards the user data packet through a narrowband channel or a broadband channel.

[0098] Reference Figure 3 , Figure 3 A schematic diagram of the process of forwarding and sending a user data packet is shown in FIG. Figure 3 As shown, when the routing management module receives a forwarding request for user data, it first uses the flow classification forwarding rule table to perform a flow classification search. If the specified rule is found, the search result is generated according to the specified rule. If there is no specified rule, the routing table is continued to be searched according to the destination IP in the request. According to the different outgoing interface channel types obtained according to the search results, the module needs to encapsulate different protocol headers to enable user data to be forwarded through narrowband or broadband channels.

[0099] In a possible implementation, the system further includes:

[0100] a sending module, configured to send an open flow table according to user classification information, and use the open flow table to guide user data packets to be sent to the routing management module;

[0101] The routing management module performs IP decapsulation on the received user data packet;

[0102] Perform IP header verification and packet assembly on the decapsulated user data packets to obtain complete user data;

[0103] The user data is sent to the target user program.

[0104] User data packets are sent up through the broadband and narrowband routing fusion system, that is, user data received from the network is sent up to the target user program. Figure 3 As shown in the figure, when the uploading module in the broadband and narrowband routing fusion system receives the uploading request of the user data packet, it sends the open flow table according to the user classification information, and uses the open flow table to guide the user data packet to be uploaded to the routing management module. The routing management module decompresses and repacks the IP header, performs IP verification and packet assembly, thereby obtaining complete user data and uploading the user data to the target user program through a narrowband channel or a broadband channel.

[0105] The embodiment of the present application receives routing data from different sources through a broadband routing module and a narrowband routing module, then uses a routing fusion module to implement fusion processing of routing data, and uses a routing management module to implement the distribution of routing data. As a result, the fusion process of broadband and narrowband routing information does not need to be transmitted across devices, which is more efficient and reliable. Moreover, the fusion of routing data is directly implemented based on existing routing switching equipment, without the need to deploy additional equipment, saving network deployment costs and simplifying the networking process. In addition, the embodiment of the present application concentrates the forwarding exports of different broadband and narrowband channels in the same device, unifies the user sending interface, better adapts to the flexible networking of flat networks, and the characteristics of on-demand access, and better supports a variety of networking application scenarios.

[0113] Sending the broadband routing protocol data to a narrowband routing module, which, after receiving the broadband routing protocol data, diffuses the data to a switching device via a wireless channel;

[0114] The narrowband routing protocol data is sent to the broadband routing module. After receiving the narrowband routing protocol data, the broadband routing module diffuses the data to the switching device through a wired channel.
