Media gateway and its method for distributing service flow IP address

Abstract

The invention discloses a media gateway which is added a address selective modular based on the former media gateway for dynamically selecting one IP address as the IP address of present service flow. The invention also discloses a method for distributing the IP address of service flow, which arranges different interface IP addresses to the each one of at least two interfaces of media gateway; and when the media gateway receives one service request and is required to distribute IP address for this service flow, the invention selects one IP address from at least two IP addresses as the service flow IP address of said service application. With said inventive media gateway and method, the media gateway can distribute IP address to the service flow according different conditions, realizing many functions that sharing the load of service flow and others, and realizing the flexibility that the media gateway selects the interface to carry the media flow.

Description

technical field [0001] The invention relates to a media gateway technology, in particular to a media gateway and a method for allocating service flow IP addresses. Background technique [0002] Due to the rapid development of IP technology, the traditional telecommunication network will gradually become the edge part of the packet backbone network. At the same time, in order to support new multimedia business applications, traditional telecommunication networks will become more and more open and introduce many new functions and physical components. Next Generation Network (NGN) is the network structure that reflects this new network environment, and it is also It is a hot technology that is currently being discussed by standard organizations, operators, and equipment manufacturers. [0003] Referring to Figure 1, generally, NGN includes four open layers: service layer, control layer, transport layer and access layer. The business layer is mainly responsible for the related...

Problems solved by technology

The interface path of the media gateway where the media stream flows out can be selected by the media gateway, but the incoming path is determined by the routing selection of the IP / MPLS network, and the media gateway cannot determine the incoming path

[0037] Although the design of this media gateway is that one physical interface is configured with one interface IP address, the media stream IP address of the media gateway still uses a fixed IP address.

Therefore, the IP address of the media stream remains unchanged. Moreover, although this design can specify the interface for sending media streams, it cannot specify the interface for receiving media streams. Therefore, although this design can achieve load sharing to a certain extent, it cannot. Accurate and controllable load sharing, so it is not conducive to the realization of other functions based on load sharing
