    摘要: Aspects of a method and system for managing multimedia traffic over Ethernet are provided. In this regard, multimedia traffic comprising one or more Ethernet frames may be identified via one or more headers comprising the frames and processed according to the identification. In this regard, general Ethernet traffic may be multiplexed into egress frames based on the identification. Similarly, ingress Ethernet frames may be demultiplexed into multimedia traffic and general traffic based on the identification. Headers utilized to identify and/or route multimedia traffic and general traffic may comprise Ethertype and/or subtype fields. Headers utilized to identify and/or route multimedia traffic and general traffic may comprise a connection identifier field. Similarly, Headers utilized to identify and/or route multimedia traffic and general traffic may comprise a data type field.

    摘要: Aspects of a method and system for implementing redundancy for streaming data in audio video bridging networks are provided. Network resources may be reserved over a plurality of network paths. Reserved resources may be utilized for the transmission and/or reception of a corresponding plurality of data streams, wherein one or more of the streams may comprise redundant data. A plurality of data streams may be transmitted and/or received by a plurality of network interface hardware devices. Similarly, a plurality of data streams may be transmitted and/or received by a plurality of ports integrated into a single network interface hardware device. Each of the plurality of data streams may be assigned a unique identifier and the identifier of a first data stream may differ by one bit from an identifier of a data stream comprising data redundant to the first data stream.

    摘要: Aspects of a method and system for securing a network utilizing IPsec and MACsec protocols are provided. In one or more network nodes, aspects of the invention may enable conversion between Ethernet packets comprising payloads secured utilizing IPsec protocols and Ethernet packets secured utilizing MACsec protocols. For example, IPsec connections may be terminated at an ingress network node and IPsec connections may be regenerated at an egress network node. Packets secured utilizing MACsec protocols may be detected based on an Ethertype. Packets comprising payloads secured utilizing IPsec protocols may be detected based on a protocol field or a next header field. The conversion may be based on a data structure stored by and/or accessible to the network nodes. Aspects of the invention may enable securing data utilizing MACsec protocols when tunneling IPsec secured data through non-IPsec enabled nodes.
