Method and system for audio/video bridging aware shortest path bridging

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.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS / INCORPORATION BY REFERENCE[0001]This patent application makes reference to, claims priority to and claims benefit from U.S. Provisional Patent Application Ser. No. 60 / 917,870 filed on May 14, 2007.[0002]The above stated provisional application is hereby incorporated herein by reference in its entirety.FIELD OF THE INVENTION[0003]Certain embodiments of the invention relate to networking. More specifically, certain embodiments of the invention relate to a method and system for Audio / Video Bridging Aware shortest path bridging.BACKGROUND OF THE INVENTION[0004]An increasing amount of data, and in particular multimedia content, transmitted over networks has led to much research into ways to improve the quality and reliability of streaming data over bridged local area networks. Accordingly, the IEEE is in the process of standardizing a suite of protocols collectively known as Audio Video Bridging and extensions thereto (collectively referred to here...

Problems solved by technology

In this regard, redundant paths may cause routing tables to fail since one address may be seen at multiple ports.

Additionally, redundant paths may result in broadcast storms, where packets are forwarded in an endless loop, consuming processing resources and bandwidth.
