Problems solved by technology

[0006] Therefore, the RB device will receive the same LSP message from multiple links at the same time, of which only one LSP message is meaningful, and the rest of the LSP messages are meaningless, thus making the synchronization of LSP messages more efficient very low

Embodiment Construction

[0031] Aiming at the problems existing in the prior art, an embodiment of the present invention provides a method for transmitting an LSP packet, which is applied to a TRILL network including multiple RB devices, so as to figure 1 It is a schematic diagram of an application scenario of an embodiment of the present invention, the TRILL network includes at least RB1, RB2, RB3, RB4, RB5, RB6 and RB7; figure 2 As shown, the method includes the following steps:

[0032] Step 201 , when there are multiple LSP messages that need to be synchronized to other RB devices on the RB device, the RB device determines the synchronization order of each LSP message by using the topology structure of the TRILL network.

[0033] Wherein, the other RB devices are RB devices that need to obtain a large number of LSP messages, such as: other RB devices may be RB devices that are currently connected to the TRILL network; or, RB devices that currently have restart operations; or, currently The RB de...

Abstract

The invention discloses a method and equipment for transmitting LSP (Link State Protocol Data Unit) messages. The method comprises the following steps that RB (Routing Bridge) equipment determines the synchronizing sequence of each LSP message by using the topological structure of a TRILL (Transparent Interconnection of Lots of Links) network; and the RB equipment transmits each LSP message to other RB equipment in sequence according to the synchronizing sequence of each LSP message. In the embodiment of the invention, when the RB equipment transmits a plurality of LSP messages, the synchronizing sequence of each LSP message is determined on the basis of the topological structure of the TRILL network, so that the synchronizing efficiency of the LSP messages is increased when a large quantity of LSP messages to be synchronized exist, and the synchronizing time of the LSP messages and the stabilization time of forwarding table entries is shortened.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and equipment for transmitting LSP (Link State Protocol Data Unit, Link State Protocol Data Unit) messages. Background technique [0002] As large data centers begin to use new technologies such as FCoE (Fibre Channel over Ethernet, Fiber Channel over Ethernet) to integrate storage transmission and IP transmission into Ethernet connections, and the STP (Spanning Tree Protocol, Spanning Tree Protocol) protocol will no longer be suitable Converged networks or the expansion of large data centers, therefore, the TRILL (Transparent Interconnection of Lots of Links, multi-link transparent interconnection) protocol came into being, and the TRILL protocol will replace the currently commonly used STP protocol. [0003] In the TRILL network, each RB (Routing Bridge, routing bridge) device passes CSNP (Complete Sequence Numbers Protocol Data Unit, full sequence pro...
