Problems solved by technology

[0003] As can be seen from the above description, the load balancing device needs to perform cumbersome network address translation (NAT), that is, to modify the destination IP and destination MAC, which will cause the performance of the device to degrade; moreover, it is necessary to manually configure the IP for each server in the server cluster address, configuration workload is heavy

Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0026] The present invention mainly utilizes anycast technology in IPv6. Anycast technology mainly relies on a new member in IPv6: anycast (Anycast) address to achieve. In the anycast technology, the load balancing device first configures the anycast address as the IP addresses of multiple service servers, and then, the load balancing device forwards the service request message to the destination service server in the server group according to a certain balancing principle.

[0027] DHCPv6 (Dynamic Host Configuration Protocol for IPv6, a dynamic host configuration protocol that supports IPv6) is a DHCP protocol based on IPv6. At present, the server participating in client network access in the broadband network is a DHCPv6 server using this protocol, wh...

Abstract

The invention discloses a method for realizing load balancing. The method comprises the steps that load balancing equipment collocates an unified anycast address to be as an objective IP (internet protocol) address of service request message for each service server according to anycast address request message sent to the load balancing equipment by each service server in a server group, and records the MAC (media access control) address of each service server; and the load balancing equipment determines one service server in the server group to be as an objective server according to the principle of load balancing when receiving the service request message from a client side, and transmits the service request message to the objective service server according to the objective IP address and the MAC of the objective service server. The invention also discloses the load balancing equipment and a system for realizing load balancing. By adopting the method, the frequency of network address conversion of the load balancing equipment is reduced.

Description

technical field [0001] The invention relates to IPv6 anycast technology, in particular to a method, device and system for realizing load balance. Background technique [0002] Load Balance (LB) is a server cluster composed of multiple servers. The load balancing device adopts a certain scheduling strategy to distribute the requests received from the client to the servers in the server cluster according to the principle of balance. Thereby, the processing capability and processing efficiency of the server cluster are improved. figure 1 It is a schematic diagram of load balancing in the prior art. The load balancing device 101 distributes the service access initiated by the client 102 to the server cluster 103 . However, in the prior art, the IP address of the server is a manually configured global unicast address, and the IP address configured for each server in the server cluster is different. When the load balancing device receives the service request message from the cli...
