Abstract
A method for providing time synchronization in a node connected to an Audio Video Bridging (AVB) Ethernet communication network includes steps of receiving static announcement messages from adjacent nodes and constituting a static grandmaster table, reselecting a grandmaster with reference to the static grandmaster table when a synchronization message timer expires, and updating the static grandmaster table according to reselection of the grandmaster. The method may rapidly time synchronization in the Audio Video Bridging (AVB) Ethernet communication network and minimize network load.
