Problems solved by technology

[0006] The problem in the above service data forwarding process is that the bearer capability layer itself has no fault recovery mechanism. Once a physical link between DREs at the bearer capability layer fails, the V-Switch private line service will be removed. That is, when the bearer capability layer detects When the status of the virtual channel fails, the connection will be closed and all affected resources will be released, which will lead to waste of resources and reduce the success rate of voice services

Embodiment Construction

[0028] The core idea of ​​the present invention is to provide a method for improving transmission reliability in a virtual switching system, realize link bundling between DREs, and set link priority, so that the connection control layer selects a path according to the link priority, which enhances The fault recovery function of the bearer capacity layer of the virtual switching system.

[0029] The present invention provides a method for improving transmission reliability in a virtual switching system, such as figure 2 Shown is a schematic diagram of link bundling at the bearer capability layer in the present invention, image 3 It is the operation flowchart of the link bundling method of the present invention, refer to below figure 2 and image 3 The link bundling process of the present invention is described. The V-Switch system includes a service control layer, a connection control layer, and a bearer capability layer. For convenience of description, the names of the re...

Abstract

This invention relates to a method for increasing stability of transmission in a virtual switch system, which connects multiple physical links among the DRE of a load ability layer to be bound logically by software to become a logic link and sets priorities of the links on the connection control layer to select links based on the link priority, which realizes the faulty resuming function of the V-Switch, when a physical link among the DRE is faulty, the DRE will switch the V-Switch special line service to other bound physical links to continue the load.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for improving transmission reliability in a virtual switching system. Background technique [0002] With the continuous increase of Internet scale, various network services emerge one after another, and advanced multimedia systems emerge in endlessly. Since multimedia services occupy a large amount of bandwidth, it is difficult to obtain reliable transmission of key services to be guaranteed by the existing network. Therefore, various QoS (Quality of Service) technologies emerge as the times require. A variety of portal-based applications and services and broadband multimedia services, including providing rich Video (video) / Audio (audio) streams, VOD (video on demand), video multicast, multimedia interaction, and high-bandwidth networks for ordinary residential users Gaming; providing business users with video conferencing, distance education, VPN (virtua...
