Abstract

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.

Claims

in an audio video bridging network, reserving network resources over a plurality of network paths; and

transmitting a plurality of data streams over said plurality of network paths utilizing said reserved network resources, wherein one or more of said plurality of data streams comprises data redundant to a first of said plurality of data streams.

2. The method according to claim 1, comprising transmitting said plurality of data streams utilizing a corresponding plurality of ports integrated into one or more network interface hardware device.

3. The method according to claim 1, comprising assigning a first stream identifier to said first of said plurality of data streams;

and

assigning an additional unique stream identifier to each of said one or more of said plurality of data streams comprising said redundant data, wherein each of said additional unique stream identifiers differs from said first stream identifier.

4. The method according to claim 3, wherein each of said additional unique stream identifiers differs from said first stream identifier by one bit.

5. The method according to claim 1, wherein each of said plurality of network paths is separate from others of said plurality of network paths.

6. The method according to claim 1, wherein each of said plurality of network paths is independent from others of said plurality of network paths.

7. A method for computer networking, the method comprising:

in an audio video bridging network, reserving network resources over a plurality of network paths; and

receiving a plurality of data streams over said plurality of network paths utilizing said reserved network resources, wherein one or more of said plurality of data streams comprises data redundant to a first of said plurality of data streams.
