Problems solved by technology

Since there are multiple gateways in the network, the terminal needs to select one of the gateways to send data packets outside the subnet. If the terminal selects a few or one gateway to forward data packets, the network traffic distribution will be uneven. Average, few or one gateway is overloaded

Embodiment 1

[0032] as attached figure 1 As shown, the embodiment of the present invention provides a method for multi-gateway load balancing, including the following steps:

[0033] 101. An access point (AP, Access Point) receives an ARP message.

[0034] There are multiple gateway nodes in the network, the access point is connected to multiple gateways through the network, the IP addresses and MAC addresses of multiple gateways are stored in the access point, and at least one terminal accesses the network through the access point; in this embodiment The ARP message may be an ARP request or an ARP response, and the ARP request or ARP response at least carries the IP address and MAC address of the terminal, and the IP address of the gateway. In step 101, the receiving of the ARP message by the access point may be: the access point receives the ARP request sent by the terminal, wherein the ARP request uses the terminal's MAC address as the source address (source) and the sending hardware a...

Embodiment 2

[0047] as attached Figure 2a As shown, there are multiple gateways (including the first gateway 21, the second gateway 22, and other gateways 23) in the network, and the access point 24 is connected to the multiple gateways through the network, and the IP addresses of the multiple gateways are stored in the access point 24. address and MAC address, at least one terminal accesses the network through the access point 24, taking one of the terminals 25 accessing the network through the access point 24 as an example, assuming that the IP address of the default gateway configured on the terminal 25 is the first gateway 21, the IP address of the first gateway 21 is IP21, and the MAC address of the first gateway 21 is MAC21. based on Figure 2a network, the embodiment of the present invention provides a multi-gateway load balancing method, such as Figure 2b shown, including the following steps:

[0048] 201. The access point 24 receives the ARP request sent by the terminal 25, w...

Embodiment 3

[0061] as attached Figure 3a As shown, there are a plurality of gateways (including the first gateway 31, the second gateway 32, and other gateways 33) in the network, and the access point 34 is connected to the plurality of gateways through the network, and the IP addresses of the plurality of gateways are stored in the access point 34. address and MAC address, at least one terminal accesses the network through the access point 34, taking one of the terminals 35 accessing the network through the access point 34 as an example, assuming that the IP address of the default gateway configured on the terminal 35 is the first gateway 31, the IP address of the first gateway 31 is IP31, and the MAC address of the first gateway 31 is MAC31. based on Figure 3a network, the embodiment of the present invention provides a multi-gateway load balancing method, such as Figure 3b shown, including the following steps:

[0062] 301. The access point 34 receives an ARP response sent by the ...

Abstract

The embodiment provides a method, a device and a communication network system for balancing a multi-gateway load, which relates to the field of electronic communication. In the method for balancing a multi-gateway load, an access point receives an ARP (Address Resolution Protocol) message; when the ARP (Address Resolution Protocol) message is used for inquiring an MAC (Media Access Control) address of a gateway by a terminal; the access point selects a gateway from multiple gateways according to a load balance strategy; the access point constitutes ARP (Address Resolution Protocol) responses according to the selected MAC (Media Access Control) address of the gateway; the access point sends the constituted ARP (Address Resolution Protocol) responses to the terminal; and the constituted ARP (Address Resolution Protocol) responses are used for establishing an ARP (Address Resolution Protocol) cache table for the terminal. Due to the adoption of the load balance strategy when selecting a gateway, the method, the device and the system can select one gateway from a plurality of gateways as average as possible in all the ARP (Address Resolution Protocol) responses sent by the access point so that the balance of data flows of multiple gateway can be realized, network congestion is reduced, and the network utilization efficiency is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of electronic communication, in particular to a method, device and communication network system for multi-gateway load balancing. Background technique [0002] When a terminal supporting the IP (Internet Protocol, Internet Protocol) protocol initially accesses the network, it first obtains the IP address of the terminal itself through the DHCP process. Generally, when the terminal obtains its own IP address, it also obtains the network mask. code, the IP address of the default gateway, the IP address of DNS, the IP address of WINS, and so on. For networks that do not support the DHCP protocol, the above addresses can be manually configured. [0003] After the terminal obtains the above-mentioned addresses, the terminal can communicate through the IP protocol. Since IP packets are often sent via Ethernet, and Ethernet devices do not recognize 32-bit or 64-bit IP addresses, IP packets are enc...
