DATA TRANSMISSION METHOD AND SYSTEM IN TRANSPARENT INTERCONNECTION OVER LOTS OF LINKS NETWORK

摘要

Disclosed are a data transmission method and system in a Transparent Interconnection over Lots of Links (TRILL) network. The method includes the following steps: a certain routing network bridge in a link or a group generating a pseudo node nickname, and notifying another routing network bridge in the network of the pseudo node nickname; the other routing network bridge calculating a path from itself to a node corresponding to the pseudo node nickname; and a routing network bridge receiving a data frame in the network processing the data frame according to the path. The present invention solves the problem in the related art of data loss due to a change generated in a designated forwarder of an end device, improving the stability and performance of the system.
