Problems solved by technology

[0004] 1. Use VRRP or HSRP to achieve load balancing, and rely on network layer routing technology to achieve network layer load balancing, which is highly dependent on network topology and does not support Layer 2 switching networks;
[0005] 2. Utilize the data transmission and broadcasting principle of the HUB device, and realize the load balancing work through the balancer, but the broadcast forwarding of the HUB device leads to frequent conflict detection in the Ethernet, resulting in low network forwarding efficiency;

Abstract

The invention discloses an Ethernet load balancing method which is self adaptive to the network, which is characterized in that the equalization algorithm is adopted to choose the response forwardingequalizer communicated among the mainframes, check the flowing network data on the response forwarding equalizer, make ARP request by replacing the mainframe and make ARP answer by replacing the mainframe simultaneously after receiving the corresponding ARP answer and forward the network data communicated among the mainframes to the chosen equalizer to be handled and thus control the forwarding ofthe network data through the equalizer. The invention has the advantages of self network adaptability without any change of the original network topology and equipment, and efficient realization of the Ethernet load balancing.

Description

technical field [0001] The invention belongs to the technical field of computer networks and relates to a method for self-adaptive load balancing of Ethernet traffic. Background technique [0002] With the continuous development of the Internet, network applications are becoming more and more abundant, network data traffic is also increasing rapidly, and the network deployment topology is becoming more and more complex. How to effectively load balance the traffic without changing the existing network environment is a must. All major network providers and operators are considering issues. Some vendors and groups have proposed their own solutions, but these solutions more or less have specific requirements for the network environment, can only be implemented under specific network conditions, and are effective for specific network applications. [0003] The following are the characteristics and problems of some prior art: [0004] 1. Use VRRP or HSRP to achieve load balancin...
