System and method for achieving distributed gateway intercommunication

Abstract

The invention discloses a system and method for achieving distributed gateway intercommunication. Multiple core networks all adopt a point-to-point technique, when the core networks are intercommunicated, after a service responsible node receives an out service requirement, a local domain gateway address is acquired from a local or a local gateway management server, an out service requirement is sent to a local gateway, the local gateway acquires a target domain gateway address from the local or the local gateway management server, and the out service requirement is transmitted to a target domain gateway. According to the system and method for achieving distributed gateway intercommunication, the problems of interconnection and interworking of different distributed gateways, selection of gateway nodes, logon of the gateway nodes, notification and the like are solved.

Description

technical field [0001] The invention relates to the field of network and communication, in particular to a system and method for realizing intercommunication of distributed gateways. Background technique [0002] A Peer to Peer (P2P for short) network is a distributed network in which the participants of the network share the resources and services possessed by the P2P network. Other nodes in the network can directly access these resources and services without going through special intermediate entities. In a P2P network, each participant is not only a resource and service provider (server), but also a resource and service acquirer (client). [0003] With the development and maturity of P2P technology and related protocols, P2P technology has also been introduced into telecom networks to control and process core network services. The basic principles are as follows: figure 1 shown. figure 1 The nodes join the P2P network through the Node Enrollment Function (NEF), and all...
