Problems solved by technology

[0004] Under the existing IP over WDM network architecture, virtual topology adjustment will change the connection relationship between routers at the IP level, which may cause network-wide routing adjustments at the IP level, which has a great impact on the forwarding mechanism of the IP network and cause network-wide routing at the IP level. shock
[0005] Moreover, to adjust the virtual topology, it is necessary to obtain the end-to-end traffic between all routers in the entire network at the IP level, but it is difficult to obtain the real-time end-to-end traffic between all routers in the entire network at the IP level. Adapt to sudden traffic changes

Abstract

The embodiment of the invention relates to a virtual cluster router system and a flow sharing method thereof, a controller and sub routers. The flow sharing method comprises the steps: a controller sends a global forwarding table of a virtual cluster router system to the sub routers, wherein the virtual cluster router system comprises a plurality of sub routers and the controller, the global forwarding table comprises a destination address prefix of data to be forwarded and an ID of a corresponding exit sub router of the virtual cluster router system; the controller receives flow information from the sub routers to the exit sub router, sent by the sub routers and establishes a flow matrix of the virtual cluster router system; and the controller determines a flow sharing mode of the virtual cluster router system according to the flow matrix of the virtual cluster router system. Through obtaining the flow information of the virtual cluster router system, flow sharing of the virtual cluster router system is conveniently carried out, the whole network routing is not influenced by virtual topological regulation in the virtual cluster router system, and thus whole network router oscillation is avoided.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a flow sharing method of a virtual cluster router system, a virtual cluster router system controller, a sub-router and a virtual cluster router system. Background technique [0002] like figure 1 The IP over WDM (optical Internet) network architecture shown generally includes three layers: the top layer is the terminal and the server, running various services used by users, such as WWW (World Wide Web, Global Information Network), FTP (File Transfer Protocol , file transfer protocol), Telnet (remote login program on the Internet), VoIP (Voice over Internet Protocol, Internet phone) and Video streaming (video streaming) and other services; the middle layer is the IP layer, and the router is responsible for real-time forwarding of various services generated The lowest layer is the optical link layer, and the WDM (Wave Divided Multiplex, wavelength division multiplexing) sys...
