Embodiment Construction

[0022] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] see figure 1 , figure 1 It is a schematic diagram of a message forwarding process in a TRansparent Interconnection of Lots of Links (TRILL) network in an embodiment of the present application. Specific steps include:

[0024] In step 101, the edge node obtains NVE information of Network Virtual Edge (NVE) devices attached to each edge node in the TRILL network, and generates an NVE information forwarding table.

[0025] see figure 2 , figure 2 It is a schematic flowchart of obtaining NVE information of NVE devices connected to each edge node by any edge node in the TRILL network in the embodiment of the present application. Specific steps include:

[0026] Step 201, when the edge node learns the NVE information of ...

Abstract

The invention provides a method for forwarding messages in the multilink transparent Internet. The method includes the steps that fringe nodes obtain NVE information of low-hung NVE devices of the fringe nodes in a TRILL network and generates a forward information list according to the obtained NVE information; the fringe nodes forward the data messages according to the forward information list when receiving the data messages sent by the low-hung NVE devices. On the basis of the same invention concept, the invention further provides a device for forwarding the messages in the multilink transparent Internet. When an overlay network is deployed, the TRILL network is used as an underlay network carrier, and the deploying process is simplified.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a message forwarding method and device in a multi-link transparent internet network. Background technique [0002] There are two situations when deploying an overlay network: [0003] 1. When the Overlay network is built in the existing network, the underlying (underlay) network based on the Internet Protocol (Internet Protocol, IP) has been built, and only the virtual overlay network needs to be deployed, which is an incremental deployment; [0004] 2. When both the underlay network and the overlay network are newly deployed, such as a new data center, the construction of the underlay network, that is, the ordinary IP network, is very complicated and the workload is huge. Contents of the invention [0005] In view of this, the present application provides a message forwarding method and device in a multi-link transparent Internet network, so as to solve the problem of ...
