Problems solved by technology

Since the multicast resources of the device are generally limited, if the multicast resources are consumed in large quantities due to the increase in the number of multicast distributions, the service provision capabilities (such as multicast services, number of VLANs, etc.) will also be restricted, resulting in The scalability of the system will also be restricted

Abstract

The embodiment of the present invention discloses a message transmission method, a network node and a message transmission system, wherein the centralized network node receives the message sent by the source edge routing bridge device through TRILL unicast encapsulation, wherein the above message is broadcast message or unknown unicast message or multicast message; the centralized network node determines the target edge routing bridge device set according to the multicast forwarding table, wherein the target routing bridge device set does not include the source edge routing bridge device, and the multicast The forwarding table includes the identification of each edge routing bridge device in the network where the above-mentioned centralized network node is located; the above-mentioned centralized network node sends the above-mentioned messages one by one to the routing bridges contained in the above-mentioned target edge routing bridge device set through TRILL unicast encapsulation equipment. The technical scheme provided by the invention can effectively save multicast resources and improve the expansion performance of the system.

Description

Technical field [0001] The present invention relates to the field of communication, in particular to a message transmission method, network node and message transmission system. Background technique [0002] Transparent Interconnection of Lots of Link (English: Transparent Interconnection of Lots of Link, abbreviation: TRILL) protocol is a routing protocol based on link state calculation. The device running TRILL protocol is called routing bridge device (English: Route Bridge, abbreviation: RB) ), a network composed of RB nodes is called a TRILL network. The RB node in the TRILL network is identified by an alias (nickname) as the RB node's identifier (Identity, abbreviation: ID), and the nickname must be unique in the entire network, that is, the nickname of each RB node is different. [0003] In the TRILL network, reverse path forwarding (English: Reverse Path Forwarding, abbreviation: RPF) is used to prevent loops of broadcast, unknown unicast, and multicast messages (for ease o...
