Embodiment Construction

[0027] figure 1 It is a schematic flow chart of the present invention, and the present invention proposes a method for realizing flow aggregation and load balancing and shunting by adopting multiple network cards cascading and working together. The method workflow is as follows:

[0028] 1) First, the network card A (multiple ports) of the first-level processor A aggregates the traffic access (the traffic access bandwidth can reach up to 40Gbps), and uses the hash algorithm to calculate the hash value of the source and destination IP.

[0029] 2) Processor configuration Configure the local machine processing traffic and the proportion of forwarding traffic for each port to the network card A. When the traffic does not exceed the processing capacity of the local machine, there is no need to forward it from the sending port.

[0030] Preferably, network card A can detect whether the output port is connected to other network cards and whether the connected network card fails, an...

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...
