Problems solved by technology

[0004] At present, many WAN port devices do not have the function of automatic load balancing in proportion. Under normal circumstances, only one WAN port is used for data transmission, and the other WAN ports are simply used as backup.

Embodiment Construction

[0016] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0017] Such as figure 1 In the embodiment of the present invention shown, Netfilter / Iptables is an IP packet filtering system integrated with the LINUX 2.4.x / 2.6.x kernel, which is divided into two parts: Netfilter and Iptables. Among them, Netfilter is a series of function call entries in the LINUX kernel IP protocol stack, which is set on the path of message processing, and it will execute the processing process before routing lookup.

[0018] The LINUX network protocol stack is a software architecture with a hierarchical structure. Messages are tran...

Abstract

The invention provides a relation method of load balance of multi-WAN (Wide Area Network) port equipment, comprising the following steps of: firstly, establishing a routing list for each WAN port; then, sending a data packet to a connection tracking marking module before routing finding to obtain the MARK value of the data packet, and evaluating the mark field of the data packet; then, carrying out routing judgment on the data packets by utilizing different routing lists in a routing finding module according to the mark field; and finally, processing the data packet according to the routing judgment of the last step, and transmitting or locally receiving and the like. According to the realization method, the function of carrying out the load balance on the multi-WAN port equipment based on a LINUX system according to a proportion is realized.

Description

technical field [0001] The invention relates to a method for implementing load balancing of multiple WAN port devices, and is specifically related to the compilation, installation and modification of the linux network protocol stack, Netfilter / Iptables, and the use of policy routing and advanced routing. Background technique [0002] In the existing technology, there are many WAN port devices, changing the original "one-to-many" WAN access mode to [0003] Into a "many-to-many" approach to meet the needs of users for more bandwidth. Multi-WAN port equipment is mainly used for increasing bandwidth, line backup, etc. Allows users to multiply bandwidth at a more economical cost. [0004] At present, many WAN port devices do not have the function of automatic load balancing in proportion. Under normal circumstances, only one WAN port is used for data transmission, and the other WAN ports are simply used as backup. Contents of the invention [0005] The technical problem to ...
