A Method for Two-Level Service Load Sharing of Layer-2 Adaptation Protocol

Abstract

The invention discloses a two-level service load sharing method of a two-layer adaptation protocol, which is suitable for an NGN network system, including: first, completing the intercommunication between the switching domain and the IP domain and performing related configuration; second, generating each The physical interface table of the AS service, the activated ASP table, and the physical interface table of each activated ASP service; 3. According to the index in the physical interface table of the AS service, the number of activated ASPs of the AS, and the physical interface number of the AS service, each The multiple IID services of the AS service perform level-1 load sharing between different activated ASPs under the corresponding AS; and 4, according to the index in the physical interface table of the activated ASP service and the physical interface number of the activated ASP service, the load is shared to the same activated ASP Multiple services on the Internet implement two-level load sharing between different flows corresponding to activated ASPs. The invention can complete the mapping of multiple IIDs and multiple SCTP couplings / flows, and realize effective load sharing.

Description

technical field [0001] The present invention relates to the technical field of NGN (Next Generation Network, next generation network), in particular to a method for two-level service load sharing of a layer-2 adaptation protocol. Background technique [0002] At present, the softswitch technology is the industry-recognized network evolution direction. This system enables users connected by various terminals to enjoy unified services, which conforms to the trend of network evolution and user demand development. The signaling gateway SG (Signaling Gateway) acts as a signaling agent for receiving and sending signaling messages at the edge of the traditional signaling network and the IP (Internet Protocol, Internet Protocol) network; its essence is to realize the connection between the traditional signaling network and the softswitch The intercommunication of signaling between them realizes the conversion function of signaling bearer layer circuit switching and IP packet, and co...

AI Technical Summary

Problems solved by technology

On the MGC and SG, the adaptation layer will map the services of the same IID to one AS, but since one AS can serve multiple IIDs, and one AS can correspond to multiple couplings, how to realize the services of multiple IIDs The mapping relationship between messages and multiple couplings / flows, and effective load sharing at the same time, does not describe any mechanism in the protocol. At present, there is no better solution in the prior art
