Abstract

Aspects of a method and system for Audio/Video Bridging aware shortest path bridging are provided. In this regard, network nodes which are AVB enabled and capable of routing information based on a desired path cost and/or a desired quality of service (QoS) may be identified, and an AVB enabled path comprising one or more of the identified nodes may be established for communication over a network. In this regard, the desired cost may be a least cost and may be the “shortest path” between two nodes in a network. Additionally, the nodes maybe identified using Shortest path Bridging protocols and/or Audio Video Bridging protocols and/or extensions thereof. Also, bridge protocol data units may be exchanged to identify the nodes.

Claims
