    摘要: Optical signals may be communicated with A/V Bridging services between an upstream link partner and a down stream link partner, each comprising an asymmetric Ethernet optical physical layer (PHY). High bandwidth A/V optical signals may be transmitted from the upstream link partner and low bandwidth optical signals may be transmitted from the downstream link partner. One or more of a time stamp, a traffic class and/or a destination address may be utilized in generating PDUs and managing communications via the asymmetric Ethernet optical PHY. The receiving link partner may register for delivery of the PDUs. An aggregate communication rate may be distributed evenly or unevenly among one or more optical links for transmission and aggregated upon reception via asymmetric Ethernet optical PHY operations. Compressed, uncompressed, encrypted and/or unencrypted optical signals may be handled. Signal processing may comprise forward error checking and clock recovery.

    摘要: Aspects of a method and system for fault resilience in Audio/Video Bridging (AVB) aware Shortest Path Bridging (SPB) networks are provided. In this regard, a path cost, which may be based at least on AVB compatibility, may be determined for each network path discovered between a first network node and a second network node. Additionally, a plurality of network paths may be selected based on the determined path cost, and a plurality of network connections may be established over the selected plurality of network paths. Also, a plurality of data streams may be transmitted and/or received via the established network connections, wherein at least one of data streams comprises data that is redundant to a first data stream. Furthermore, a primary data stream may be conveyed via a first network connection and one or more redundant data streams may be conveyed via a second network connection.

    摘要: 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.
