Method, device and system for switching flow of multilayer network

Abstract

The invention relates to a method, a device and a system for switching flow of a multilayer network. The method comprises the steps of: indicating a lower layer network service transmission point to establish a through light path by an upper layer network response service bearing point under the drive of a through light path server; configuring a protection label switched path used for bearing network flow between service bearing points at two ends of the through light path, wherein the network flow born on the protection label switched path is transmitted through the through light path; and switching the network flow born on the original label switched path and passing between the service bearing points at two ends of the through light path into the protection label switched path. The invention shortens the time of possibly causing the service damage in the process of switching the network flow to the through light path, and improves the user experience.

Description

technical field [0001] The present invention relates to communication technology, in particular to a multi-layer network flow switching method, device and system. Background technique [0002] With the rapid development of broadband Internet in recent years, services such as platform network (WEB2.0), point-to-point (P2P for short), video sharing and Internet Protocol Television (IPTV for short) continue to rise, and network traffic will Maintain an exponential growth trend for a long time. It can be seen that in the next few years, the capacity problem will become the biggest challenge for the development of communication networks. [0003] One way to solve the capacity problem is to divert the traffic in the network. For large-grained traffic, it is directly passed through the optical layer channel instead of being processed by other routers between the routers at both ends of the optical layer channel. A communication network with a layered network structure (ie, a mult...

Problems solved by technology

[0004] In the process of implementing the embodiments of the present invention, the inventors found that in the prior art, in the process of dynamically unblocking traffic based on MTE technology, it takes a long time from the establishment of the direct optical path to the switching of traffic to the direct optical path. During the process, the business may be damaged for a long time, which affects the user experience
