Service controlling method in virtual exchange system

Abstract

The method includes following steps: in the virtual switch system, divides the VSC in connection control layer and DRE in bearing power layer into two devices independently each other; the device of service control layer in the virtual switch system builds the connection with VSC belonging to the calling user directly connected with itself; the device of service control above sends resource request to the VSC belonging to the calling user; the VSC belonging to the calling user applies to the VSC belonging to the called party for bandwidth resources through each downs stream VSC; if the application is successful, the message responding to the resource request is sent back to the device in service control layer; otherwise, continues to apply for bandwidth resources to VSC in called party.

Description

technical field [0001] The present invention relates to a virtual switch (Virtual Switch,) technology, in particular to a system for service control in the V-Switch system. Background technique [0002] The V-Switch architecture has complete Ethernet virtual local area network (VLAN) switching and scheduling functions, flexible service scheduling and means of establishment and adjustment, rich and scalable Layer 2 service provision capabilities, comprehensive operation and maintenance management tools and information. Therefore, the V-Switch system is widely used in providing Ethernet virtual private line services, Ethernet virtual local area network services, Ethernet circuit emulation services, and scheduling of carrier Ethernet services. [0003] figure 1 It is a schematic diagram of the model structure of the V-Switch system. see figure 1 , the model structure of the V-Switch system is logically divided into a service control layer, a connection control layer and a b...

Problems solved by technology

Therefore, when performing user access authentication and service control of call requests, not only the SCR device at the service control layer needs to intervene, but also the bearer devices at the bearer capability layer and connection control layer. On these bearer devices, not only need to support The service flow also needs to support the signaling flow. In this way, not only the entire signaling pathfinding process is quite complicated, but also puts forward higher requirements on the processing capability of the bearer equipment, and it is difficult to upgrade the bearer equipment, and the topology and management are too complicated. complicated question
