Problems solved by technology

[0003] When the port status of the SPB device changes, it needs to be notified to other nodes as soon as possible. The speed of notification will directly affect the convergence speed of the network topology. If the convergence speed is slow, serious packet loss will occur.
[0004] However, in the prior art, when an LSP message is notified, it is usually transmitted hop by hop. If the LSP message whose port status changes is diffused to the entire SPB network, it will take a long time, which will lead to a slow topology convergence speed. Severe packet loss caused by slow

Embodiment Construction

[0018] In order to make the purpose, technical solution and advantages of the present application clearer, the solution of the present application will be further described in detail below with reference to the accompanying drawings.

[0019] In order to solve the problems in the prior art, the present invention provides a method and device for fast notification of LSP messages.

[0020] figure 1 It is a schematic diagram of the networking environment applied by the LSP message fast notification method of the present invention, the networking can be the SPB network that has run the SPB protocol, and the SPB network includes a controller, a switch ( figure 1 Not shown in ) and multiple SPB devices that can communicate with the controller respectively (such as figure 1 SPB1, SPB2, SPB3, SPB4, SPB5, and SPB6 in SPB1, SPB2, SPB3, SPB4, SPB5, and SPB6), each SPB device may have multiple ports (for example, Port2, Port3 on SPB2), and the controller may be an SDN controller.

Abstract

The present invention provides a fast notification method and device for an LSP message, wherein the method includes: receiving an LSP message sent by an SPB device in an SPB network; All other SPB devices send LSP packets, so that all other SPB devices recalculate forwarding paths according to the LSP packets. The invention can greatly speed up the notification time of the LSP message, and effectively reduces the number of lost packets.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method and device for quickly notifying an LSP message. Background technique [0002] The SPB (Shortest Path Bridge, shortest path bridge) network is composed of SPB devices such as backbone network edge bridge (BEB), backbone network core bridge (BCB), and a backbone network between SPB devices. After each SPB device is started, all link state information of the local SPB device, MAC (Media Access Control, Media Access Control) address of the SPB device, B-VLAN (Backbone-Virtual Local Area Network, backbone network virtual local area network) And the corresponding relationship of I-SID (Backbone-Service Instance Identifier, backbone network service instance number) is encapsulated into an LSP message (Link State Protocol link state protocol), and then passed to other SPB devices in the SPB network. After all the SPB devices in the SPB network have completed the transmi...
