    摘要： Aspects of a method and system for determination and exchange of network timing information are provided. In this regard, for each network hop traversed by a packet, a propagation delay of said network hop may be determined. Moreover, the propagation delay, and/or a hop length calculated utilizing the propagation delay, may be appended to the packet. The packet may, for example, be a MMRP registration packet or a SRP reservation packet. The packet may be dropped in instances that the propagation delay and/or length of a one or more traversed network hops is outside a determined range. The hop length may be determined by multiplying the propagation delay by a speed of propagation on the hop. The speed of propagation may be determined based on the physical layer technology associated with the network hop. Digital rights management may be implemented for media communicated on the network hop based at least in part on the hop length or the propagation delay. In this regard, use of media content may be restricted to a specified location.

    摘要： A network device comprising an asymmetric, multi-rate, Ethernet, optical MAC and an asymmetric, multi-rate, Ethernet, optical PHY, communicates optical signals via a network utilizing NV bridging services. Higher bandwidth NV optical signals are communicated and lower bandwidth optical signals are received and/or vice versa. Optical signals may be communicated based on a plurality of different single mode Ethernet optical protocols and/or different multimode Ethernet optical protocols. Optical signals may be communicated at 10 Gbps in one direction and at a lower rate in a reverse direction. Extended range mode may be utilized. PDUs comprise time stamps, traffic class designations and/or destination addresses. Data rate requests, resource reservation messages and/or registration for delivery of PDUs may be communicated. Time stamps enable end to end transport within a specified latency target. Video signals may be compressed, uncompressed, encrypted, unencrypted and/or formatted for a video display interface.

    摘要： A first network device may select a plurality of network paths for establishing a plurality of network connections to a second network device. The selection may be based on support of IEEE Audio Video Bridging (AVB) protocols. The first network device may establish at least one of the plurality of connections over each of the selected network paths. The first network device may concurrently transmit and/or receive a plurality of data streams via the established plurality of network connections. At least a second one of the plurality of data streams may comprise data that is redundant to a first one of the plurality of data streams. One of the plurality of network connections may be selected for conveying a primary data stream based on determined path costs of the plurality of network paths, where non-AVB links may be assigned higher path costs than AVB link.
