Description

Technical Field

[0001] The invention belongs to the technical field of computer networks, and in particular relates to a method and system for processing data by multiple gateways in a local area network. Background Art

[0002] EasyMesh is now commonly used to mesh multiple wireless routers to expand the coverage of wireless networks. EasyMesh is a master-slave network system. The network consists of a controller device and multiple proxy devices. The controller device is mainly responsible for dynamically configuring the proxy devices in the network. It is also the only gateway in the EasyMesh network. All network traffic in the LAN needs to be routed to the Internet through the gateway.

[0003] Because there can only be one gateway in the EasyMesh network, the gateway is the only traffic outlet of the EasyMesh LAN, and all public network traffic in the network needs to be routed through the gateway. Network performance is limited by the link between the gateway and other routers and the Internet access bandwidth, which is the performance bottleneck of the entire LAN. When the gateway needs to process a large amount of public network traffic at the same time, the network bandwidth and latency performance of the EasyMesh network will be greatly reduced due to the limitation of processing capacity, resulting in poor user experience. Summary of the invention

[0004] The present invention proposes a method and system for processing data by multiple gateways in a local area network, which greatly improves the network performance of the EasyMesh network by expanding the capacity of the EasyMesh network to support multiple gateways and multiple interfaces.

[0005] A first aspect of the present invention provides a method for implementing multi-gateway data processing in a local area network, the method comprising:

[0006] Determine the traffic destination of the traffic data packet sent by the STA, and send the traffic data packet whose traffic destination is the Internet as a first data packet to the first device;

[0007] Generate node routing rules according to the actual network situation of EasyMesh networking, and configure local routing rules of the controller device and local routing rules of the proxy device according to the node routing rules; wherein the EasyMesh networking includes a controller device and several proxy devices;

[0008] According to the local routing rule of the controller device and the local routing rule of the proxy device, matching and identifying the first data packet sent by the first device and generating a tag value of the first data packet;

[0009] According to the tag value of the first data packet, the routing table corresponding to the first data packet is determined, and the first data packet is sent to the Internet according to the routing table; wherein the routing table is established for all gateways and all network interfaces of the EasyMesh network according to the actual network situation of the EasyMesh network.

[0010] The above scheme configures local routing rules for the controller device and the proxy device according to the actual network situation of the EasyMesh network, and then matches and identifies the first data packet with the traffic destination being the Internet according to the local routing rules configured on the proxy device, and adds a tag value to the first data packet; the routing table of the corresponding gateway and network interface is determined according to the tag value, so as to support multiple gateways and multiple network interfaces in the EasyMesh network, so that the EasyMesh network can use multiple gateways to process traffic data at the same time, greatly improving the network performance of the EasyMesh network.

[0011] In a possible implementation method of the first aspect, determining a traffic destination of a traffic data packet sent by the STA, and sending a traffic data packet whose traffic destination is the Internet as a first data packet to the first device, specifically:

[0012] Determine the traffic destination of the traffic data packet sent by the STA;

[0013] If the traffic destination of the traffic data packet is the Internet, sending the traffic data packet as a first data packet to the first device;

[0014] If the traffic destination of the traffic data packet is not the Internet, the traffic data packet is sent to the corresponding traffic destination.

[0015] The above solution identifies the traffic data packets sent by STA and directly releases the traffic data packets whose destination is not the Internet to ensure the normal operation of the basic services of EasyMesh networking; the traffic data packets whose destination is the Internet are sent to the first device to provide data support for selecting the route to the Internet.

[0016] In a possible implementation method of the first aspect, a node routing rule is generated according to an actual network condition of the EasyMesh network, specifically:

[0017] When the status of the EasyMesh network changes, the network access capability information of the proxy device is sent to the controller device; wherein the network access capability information includes the network access status of the proxy device and the number of access interfaces;

[0018] According to the network access capability information, the controller device generates node routing rules through a preset algorithm program.

[0019] When the status of the EasyMesh network changes, the above scheme collects the network access status and the number of access interfaces from the proxy device and sends them to the controller device. The controller device formulates node routing rules that conform to the actual network access capabilities based on the network access capabilities of each proxy device, so that the controller device and each proxy device can normally allocate routing tables for traffic data packets according to their actual network access capabilities, avoiding the controller device and each proxy device from being overloaded due to unreasonable node routing rules.

[0020] In a possible implementation method of the first aspect, configuring a local routing rule of a controller device and a local routing rule of a proxy device according to the node routing rule is specifically as follows:

[0021] According to the node routing rule, configure the local routing rule of the controller device;

[0022] According to the node routing rule, issuing a rule configuration instruction to the proxy device;

[0023] According to the rule configuration instruction and the node routing rule, the local routing rule of the proxy device is configured.

[0024] The above scheme configures the controller device and the proxy device respectively according to the generated node routing rules, so that the controller device and the proxy device can match and identify the incoming data packets and generate tag values.

[0025] In a possible implementation method of the first aspect, according to a local routing rule of the controller device and a local routing rule of the proxy device, matching and identifying a first data packet sent by the first device and generating a tag value of the first data packet are specifically as follows:

[0026] According to the local routing rule of the proxy device, matching and identifying the first data packet sent by the first device;

[0027] If there is a local routing rule of the proxy device that matches the first data packet, generating a first routing decision according to the local routing rule of the proxy device that matches the first data packet, and generating a tag value of the first data packet according to the first routing decision;

[0028] If there is no local routing rule of the proxy device that matches the first data packet, the first data packet is sent to the controller device, so that the controller device sends the first data packet to the Internet according to the local routing rule of the controller device.

[0029] In the above scheme, the data packet is first matched and identified according to the local routing rules of the proxy device. If the local routing rules of the proxy device cannot be matched, the controller device will forward the data packet; if the local routing rules of the proxy device can be matched, the proxy device will add a tag value to the data packet to provide data support for the subsequent allocation of routing tables for the data packet according to the tag value, and also realize multi-gateway processing of network traffic, which greatly reduces the operating pressure of the controller device in the EasyMesh network and improves the network performance of the EasyMesh network.

[0031] The traffic data packet identification module is used to determine the traffic destination of the traffic data packet sent by the STA, and send the traffic data packet with the traffic destination being the Internet as the first data packet to the first device;

[0032] The routing rule configuration module is used to generate node routing rules according to the actual network situation of the EasyMesh network, and configure the local routing rules of the controller device and the local routing rules of the proxy device according to the node routing rules; wherein the EasyMesh network includes a controller device and several proxy devices;

[0033] The tag value generating module is used to match and identify the first data packet sent by the first device and generate a tag value of the first data packet according to the local routing rule of the controller device and the local routing rule of the proxy device;

[0034] The routing table allocation module is used to determine the routing table corresponding to the first data packet according to the tag value of the first data packet, and send the first data packet to the Internet according to the routing table; wherein the routing table is established for all gateways and all network interfaces of the EasyMesh network according to the actual network conditions of the EasyMesh network.

[0035] In a possible implementation of the second aspect, the traffic data packet identification module includes: a traffic destination determination unit;

[0036] The traffic destination determination unit is used to determine the traffic destination of the traffic data packet sent by the STA; if the traffic destination of the traffic data packet is the Internet, the traffic data packet is sent to the first device as the first data packet; if the traffic destination of the traffic data packet is not the Internet, the traffic data packet is sent to the corresponding traffic destination.

[0037] In a possible implementation of the second aspect, the routing rule configuration module includes: a node routing rule generation unit;

[0038] The node routing rule generation unit is used to send the network access capability information of the proxy device to the controller device when the state of the EasyMesh networking changes; wherein the network access capability information includes the network access status of the proxy device and the number of access interfaces; and according to the network access capability information, the controller device generates node routing rules through a preset algorithm program.

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] It should be understood that the step numbers used in this article are only for the convenience of description and are not intended to limit the order in which the steps are executed.

[0051] like Figure 1 As shown, Figure 1 A specific flow chart of a method for processing data by multiple gateways in a local area network is provided for a certain embodiment of the present invention. The method for processing data by multiple gateways in a local area network of this embodiment includes steps S1 to S4, which are described in detail as follows:

[0052] Step S1, determining the traffic destination of the traffic data packet sent by the STA, and sending the traffic data packet whose traffic destination is the Internet as a first data packet to the first device;

[0053] In this step, the traffic destination of the traffic data packet sent by the STA is first determined. If the traffic data packet is user network traffic, the traffic destination of the traffic data packet is the Internet.

[0054] If the traffic destination of the traffic data packet is the Internet, redirect the network layer of the EasyMesh network and send the traffic data packet as the first data packet to the netfilter queue in the network layer iptables;

[0055] If the traffic destination of the traffic data packet is not the Internet, that is, the traffic data packet is intranet traffic, ARP traffic, DHCP traffic, etc., then the traffic data packet is directly sent to the corresponding traffic destination to ensure the normal operation of the basic services of EasyMesh networking.

[0056] In addition, it is necessary to establish a routing table for all gateways and all network interfaces of the EasyMesh network according to the actual network conditions of the EasyMesh network.

[0057] In order to identify the traffic destination of the traffic data packet, a series of configurations need to be performed on the router Linux system to modify the EasyMesh networking workflow; this configuration needs to be deployed on each EasyMesh networking device.

[0058] In order to better describe the overall principle of this embodiment, Figure 2 The overall principle diagram of the method for processing data by multiple gateways in the local area network of this embodiment is provided. As shown in the figure, the system traffic policy configuration group is a series of configurations performed on the router Linux system, and the application layer routing decision program is used to select routes for traffic data packets with a traffic destination of the Internet; wherein the application layer routing decision program is a master-slave architecture distributed program running on the router of the EasyMesh network, the master node program runs on the controller device, and the slave node program runs on all other proxy devices; the router first intercepts the traffic data packets sent by the STA at the link layer, and identifies the traffic destinations of these traffic data packets, and then sends the traffic data packets with a traffic destination of the Internet to the netfilter queue in the network layer iptables, and the netfilter queue then sends the traffic data packets to the application layer, and the application layer routing decision program adds a tag value to select a route to the Internet, thereby realizing the multi-gateway and multi-interface processing of network traffic in the EasyMesh network.

[0059] Step S2, generating node routing rules according to the actual network situation of the EasyMesh network, and configuring the local routing rules of the controller device and the local routing rules of the proxy device according to the node routing rules;

[0060] In this step, the controller device will automatically generate node routing rules based on the network access capability information of all proxy devices or obtain node routing rules configured by the network administrator. The controller device then uses the network access capability information to generate node routing rules, and issues rule configuration instructions to each proxy device based on the node routing rules, so that the proxy device configures the local routing rules of the proxy device based on the rule configuration instructions and the node routing rules; at the same time, the controller device can also configure its own local routing rules based on the node routing rules, so that the controller device has the same functions as the proxy device, matching and identifying incoming traffic data packets according to the local routing rules, making routing decisions and adding tag values.

[0061] Among them, the network access capability information of all proxy devices reports the network access status and the number of access interfaces of the proxy devices whose status of EasyMesh networking changes to the controller device when the status of EasyMesh networking changes, the application layer routing decision program is initialized, or the local network connection status changes, so that the controller device can dynamically generate node routing rules.

[0062] In order to better describe the process of how controller devices and node devices configure local routing rules, Figure 3 A node routing rule configuration process diagram of this embodiment is provided. As shown in the figure, the proxy device first checks its own network access capability through the slave node application layer routing decision program, and then reports its own network access capability to the controller device. The controller device calculates the node routing rule according to the master node application layer routing decision program and sends a rule configuration instruction to the proxy device. After receiving the rule configuration instruction, the proxy device configures the local routing rule according to the rule configuration instruction, completing the real-time update of the local routing rule by the proxy device and the controller device to meet the current working status of the EasyMesh network.

[0063] Step S3, matching and identifying the first data packet sent by the first device and generating a tag value of the first data packet according to the local routing rule of the controller device and the local routing rule of the proxy device;

[0064] In this step, the netfilter queue sends the first data packet to the application layer routing policy program of the proxy device for identification, and the proxy device matches and identifies the first data packet according to the local routing rule.

[0065] If there is a local routing rule of the proxy device that matches the first data packet, generate a first routing decision according to the local routing rule of the proxy device that matches the first data packet, and add a tag value of the first data packet generated by the first routing decision to the first data packet;

[0066] If there is no local routing rule of the proxy device that matches the first data packet, the first data packet is sent to the controller device according to the control rule preset in the EasyMesh network, so that the controller device sends the first data packet to the Internet according to the local routing rule of the controller device.

[0067] Step S4, determining a routing table corresponding to the first data packet according to the tag value of the first data packet, and sending the first data packet to the Internet according to the routing table;

[0068] In this step, after adding a tag value to the first data packet, the first data packet is transmitted back to the network layer and the corresponding routing table is determined according to the tag value of the first data packet. Then, the next sending path of the first data packet is set according to the corresponding routing table, and the first data packet is sent to the Internet.

[0069] Furthermore, Figure 4 A typical application deployment scenario diagram of a method for processing data by multiple gateways in a local area network provided for a certain embodiment of the present invention. As shown in the figure, R1 is the controller device of the EasyMesh network, which accesses the Internet through a wired WAN interface; R2 is the proxy device of the EasyMesh network, which accesses the Internet through a wired WAN interface and a 4G / 5G cellular connection; R3 is the proxy device of the EasyMesh network, which does not have an interface that can connect to the Internet, so it cannot access the Internet. STA1, STA2, and STA3 are all user access terminals, which access R2 and R3 through WiFi connections and send data packets to the Internet. Based on this scenario, the operation process of the EasyMesh network in this embodiment is as follows:

[0070] (1) R2 and R3 report their access capabilities to the controller device R1. R1 generates routing configuration instructions based on this information and sends them to R2 and R3. The specific content of the routing configuration instructions, for example, requires R2 to send STA1's traffic data packets through R2's wired WAN, and STA2's traffic data packets through R2's cellular connection, requires R3 to send STA3's traffic data packets through R1's wired WAN, and R1 needs to send the traffic data packets from STA3 from its own wired WAN;

[0071] (2) R1, R2, and R3 configure local routing rules according to routing configuration instructions;

[0072] (3) After STA1's traffic data packet is sent to R2, it is identified by the rules of the link layer and the network layer. R2 selects its own wired WAN for STA1's traffic data packet according to the local routing rules, and then adds the corresponding tag value to select the routing table of STA1's traffic data packet; then STA1's traffic data packet is sent through R2's wired WAN connection; similarly, STA2's traffic data packet goes through the same steps and is finally sent through R2's cellular connection;

[0073] (4) STA3's traffic data packet arrives at R3. After being identified by the link layer and network layer rules, the traffic data packet is transmitted to R3's slave node application layer routing decision program. R3 selects STA3's traffic data packet to be sent to R1 according to the slave node application layer routing decision program, and adds the corresponding tag value to determine that STA3's traffic data packet is sent to R1's routing table; after R1 receives STA3's traffic data packet, it is transmitted to R1's master node application layer routing decision program after the same link layer and network layer rules are identified. R1 matches STA3's traffic data packet with the local routing rules according to the master node application layer routing decision program, and adds the corresponding tag value to STA3's traffic data packet, and finally sends the traffic data packet through R1's own wired WAN connection.
