Embodiment Construction

[0021] See figure 1 , a schematic diagram of a CGN board deployment in an embodiment of the present application, which includes a service board connected to the public network, that is, a CGN board, and an access board connected to a private network, that is, a BRAS access board, wherein the service board and the access board are in figure 1 The deployment positions in the . figure 1 The switching network in is a switching network formed inside the service board and the access board, which is used to realize the information exchange between the service board and the access board. The CGN board is deployed for address translation between the private network and the public network. Since only one authorized user group can be configured under a domain, when a large number of users go online under this authorized user group for business processing, the traffic of different users can only be processed through the current service board, which will cause great impact on the current ...

Abstract

The invention provides a load balancing method and a load balancing device. When users on a first service board migrate to a second service board, a control module can calculate access users belonging to a second user group in view of the current access users according to the second user group corresponding to the second service board, user table entries corresponding to the access users belonging to the second user group in a first user group are synchronized to the second service board, second user group table entries are obtained, an access board is controlled to update access users corresponding to the second user group table entries, flow of the access users belonging to the second user group is guided to the second service board for being processed, and thus, effects of automatically adjusting the loads are achieved, and no perception and no packet loss of the user can be realized.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a load balancing method and device. Background technique [0002] NAT (Network Address Translation, Network Address Translation) is the process of converting the IP address in the IP datagram header to another IP address. When the message from the internal network to the external network passes through the NAT device, the NAT device will replace the source IP address in the original message with a legal public network address to communicate with the external network. [0003] CGN (Carrier Grade NAT, Carrier Grade NAT) is deployed in the carrier network to realize the translation of a large number of user addresses. Therefore, CGN has far higher requirements on capacity, performance, and reliability than traditional NAT. Contents of the invention [0004] In view of this, the present application provides a load balancing method and device to solve the prob...
