Embodiment Construction

[0049] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0050] In a TRILL network, each RB calculates a multicast distribution tree for guiding multi-purpose message forwarding according to the network topology. Moreover, each RB generates its own multicast forwarding entry based on the multicast distribution tree. For the specific process of calculating the multicast distribution tree and generating the multicast forwarding entry by the RB, reference is made to the prior art, which is not described in detail in the present invention.

[0051] In the embodiment of the present invention, the index corresponding to the outgoing interface list is set, the multicast forwarding entry in the TRILL network does not directly record the outgoing interface list of the multipurpose message, but records the index corresponding to ...

Abstract

The invention proposes a message forwarding method and device in a transparent interconnection of multiple links (TRILL) network. The method includes: receiving a multi-purpose message; querying a multicast forwarding table item based on the forwarding information of the multi-purpose message to obtain an index corresponding to the multi-purpose message; searching an index association table based on the index corresponding to the multi-purpose message to obtain the multi-purpose message outbound interface list; forward multipurpose packets based on the outbound interface list of multipurpose packets.

Description

technical field [0001] The invention belongs to the technical field of network communication, in particular to a message forwarding method and device in a transparent interconnection of multiple links (TRILL) network. Background technique [0002] The Transparent Interconnection of Lots of Links (TRILL) protocol introduces the design idea of ​​Intermediate System-to-Intermediate System (IS-IS) of Layer 3 routing technology into the Layer 2 network, thus integrating the Layer 2 The simplicity and flexibility of the layer network and the stability, scalability and high performance of the three-layer network are organically integrated, which is very suitable for the data center to build a large-scale two-layer network. [0003] A device running the TRILL protocol is called a Routing Bridge (RB). According to the position of RB in the TRILL network, it can be divided into ingress (Ingress) RB, intermediate (Transit) RB, and egress (Egress) RB, respectively representing the ingr...
