Multi-network-card load balancing system and method

Abstract

The invention provides a system and a method for realizing flow gathering and load balancing and shunting through cascade teamwork of multiple network cards. The system comprises multi-stage network cards, wherein the network card of a processor in the last stage is subjected to homologous and homoclinic shunting according to the configuration proportion, part of the flow is uploaded to a local machine for treatment, and other flow is proportionally forwarded to the network card in the next stage. By adopting the system and the method for realizing flow collection and load balancing and shunting through cascade teamwork of multiple network cards, special shunting equipment can be completely omitted, the network cards can serve as not only flow access equipment but also flow gathering and shunting equipment, so that the investment cost of users is greatly lowered; besides, the multi-network-card cascade method has good expandability, can be expanded to three stages or even more stages till meeting the stand-alone treatment capacity.

Description

technical field [0001] The invention belongs to the field of computer network communication, and in particular relates to a multi-network card load balancing system and method. Background technique [0002] In terms of Internet content auditing technology, generally speaking, packets belonging to the same pair of IPs need to be processed together, but in the network environment, bidirectional traffic of the same pair of IPs is often distributed on different network cables, so multiple network cables need to be Aggregate the traffic on it. When the aggregated traffic exceeds the processing capacity of a single processor, it is also necessary to split the flow of the same source and destination according to the source and destination IP addresses, so that the packets of the same pair of IPs are allocated to one processor for processing. [0003] Patent No. CN200910083155.5 (a hardware distribution method for IP messages) discloses a hardware distribution method for IP message...

Problems solved by technology

This method is suitable for systems where a single interconnection network cannot meet the performance requirements for inter-computer communication

[0005] In the prior art, the above-mentioned traffic convergence and distribution work is realized by special equipment, which is generally realized by ATCA chassis, which can handle very large traffic, and at the same time, the cost is also very high, often at the level of one million yuan. For some traffic Not a very large application scenario, this kind of equipment is too expensive, and the utilization rate is very low
