Multi-route network and route switching method

Abstract

The invention relates to a multi-route network and a route switching method. The multi-route network provided by the method comprises a terminal, a server, multiple routes and multiple disaster-tolerant equipment, wherein the multiple routes and the multiple disaster-tolerant equipment are arranged between the terminal and the server; the multiple disaster-tolerant equipment are respectively provided with a driving link blocking module; and when a link of the disaster-tolerant equipment in which the driving link blocking module is positioned and a certain route breaks down, the driving link blocking modules can block links among the disaster-tolerant equipment and the other rest routes. The invention has the advantages that when the link of the disaster-tolerant equipment in which the driving link blocking modules are positioned and a certain route breaks down, the driving link blocking modules can block the link of the disaster-tolerant equipment and each rest route thereby avoiding the data loss.

Description

technical field [0001] The invention relates to the technical fields of communication and computer, in particular to a multi-routing network and a routing switching method. Background technique [0002] In the communication system, under the requirement of high equipment reliability, two or more routers are usually used for backup or load sharing. In order for the backup device to replace the original active device, the business can be quickly switched to the backup device, and it is necessary to quickly switch the route when the device or the link of the device fails. [0003] If there is a device or link failure on one side of the routing device, the service flow and traffic on the other side will still flow to this device, which will cause the traffic loss of these users and service failure. [0004] Especially in the situation that most of the multi-routing methods of the current network adopt the slow Hello mechanism, especially in routing protocols, without the help o...

AI Technical Summary

Problems solved by technology

When the data rate reaches gigabit, the long fault detection time represents a large amount of data loss, and there is no way to detect the state of the link for nodes that do not allow routing protocols

At the same time, the existing IP network does not have the intermittent fault repair function of less than a second, and the traditional routing architecture has limited capabilities in accurate fault detection for real-time applications (such as voice)
