Embodiment Construction

[0041] In order to use lower system overhead and realize the solution of load sharing according to the resource status of each server, the present invention mainly utilizes anycast technology in IPV6. The anycast technology mainly relies on the new member in IPV6: anycast address to realize. In the anycast technology, the anycast address is first configured as the IP addresses of multiple servers, and then the forwarding device forwards the message sent to the anycast address to one of the servers corresponding to the anycast address according to a certain forwarding strategy.

[0042]In the anycast technology, the forwarding device mainly relies on the anycast neighbor entry corresponding to the anycast address to forward the packet sent to the anycast address to one of the servers corresponding to the anycast address. Therefore, in the technical solution of the present invention, in order to realize load sharing, the same anycast address can be configured for each server tha...

Abstract

The invention discloses a technical proposal for implementing load sharing based on anycast technique, which combines various servers to be load-shared to form an anycast group, allows the retransmission device to obtain the resource state of the server based on the neighbor discovery protocol of the anycast technique, the retransmission device connected with anycast group serves as dispatching device and receives the message from the anycast group and then transfers the received message according to the resource state of each server recorded in the anycast neighbor list, completing the load sharing. The implementation of the load sharing purpose is dependent on the complete utilization and improvement of the existing anycast technique in the inventive technical proposal, therefore, the invention can reduce the system overhead required for load sharing in a certain extent and greatly reduce the waste of system resources.

Description

technical field [0001] The invention relates to IPV6 anycast technology, in particular to a method for realizing load sharing by using anycast technology, a forwarding device for realizing load sharing by using anycast technology and a system for realizing load sharing by using anycast technology. Background technique [0002] Load sharing is in a server set composed of multiple servers, using a certain scheduling strategy to distribute the requests received from the outside to each server in the server set according to the principle of balance, so as to improve the processing capacity and processing efficiency of the server set . In order to achieve a better effect of load sharing, many scheduling strategies will perform load sharing according to the current resource status of each server in the server set when performing load sharing. For example, Least-Connection Scheduling, Weighted Least-Connection Scheduling, Locality-Based Least Connections Scheduling, Locality-Based...
