Abstract
Provided are a network system supporting a spanning tree protocol (STP), a relay apparatus thereof, and a method of creating a spanning tree. Proposed is a method of creating a tree topology, between AVB bridges, using a STP message including a group MAC address which is different from that used in a non-AVB (Audio Video Bridging) bridge (that is, a bridge without the function of AVB), in order to form a minimum number of AVB clouds. Therefore, it is possible to efficiently ensure transmission quality of a multimedia stream such as an AVB stream.
