Abstract

Aspects of a method and system for managing network resources in audio/video bridging enabled networks are provided. In this regard, network resources reserved via AVB may be allocated for administrative and/or control traffic. Additionally, administrative and/or control data may be assigned highest priority for routing in the network. In this regard, priority of traffic may be determined via one or more bits of a VLAN tag associated with the traffic. For each AVB stream registered in the network, there may be a corresponding portion of the reserved network resources allocated for administrative and/or control data. The portion of reserved network resources allocated for administrative and/or control data may be based on past, present, or expected network statistics. Portions of the reserved resources not allocated for administrative and/or control data may be utilized for communicating one or more multimedia streams. In this regard, the unallocated resources may be distributed amongst the one or more multimedia streams. Allocating reserved resources for administrative and/or control traffic may ensure reliable communication of the administrative and/or control traffic, by preventing one or more multimedia streams from monopolizing network resources.

Claims

1. A method for communication, the method comprising:

reserving, via AVB, resources in a network node; and

allocating at least a portion of said reserved resources for administrative and/or control traffic to and/or from said network node.

2. The method according to claim 1, comprising assigning said administrative and/or control data a highest priority.

3. The method according to claim 2, wherein said priority is identified in a VLAN tag of an Ethernet frame comprising said administrative and/or control data.

4. The method according to claim 1, comprising allocating said at least a portion of said reserved resources for each AVB stream registered in said network node.

5. The method according to claim 1, comprising dynamically allocating said at least a portion of said reserved resources based on past and/or present network statistics.

6. The method according to claim 1, comprising utilizing unallocated portions of said reserved network resources for communicating one or more multimedia streams.

7. The method according to claim 6, comprising distributing said communicated one or more multimedia streams among said unallocated portions of said network resources.

8. The method according to claim 1, comprising allocating said at least a portion of said reserved resources to enable reliable communication of said administrative and/or control traffic when communicating one or more multimedia streams.

9. A machine-readable storage having stored thereon, a computer program having at least one code section for communication, the at least one code section being executable by a machine for causing the machine to perform steps comprising:

reserving, via AVB, resources in a network node; and

allocating at least a portion of said reserved resources for administrative and/or control traffic to and/or from said network node.

10. The machine-readable storage according to claim 9, wherein said at least one code section enables assigning said administrative and/or control data a highest priority.

11. The machine-readable storage according to claim 10, wherein said priority is identified in a VLAN tag of an Ethernet frame comprising said administrative and/or control data.

12. The machine-readable storage according to claim 9, wherein said at least one code section enables allocating said at least a portion of said reserved resources for each AVB stream registered in said network node.

13. The machine-readable storage according to claim 9, wherein said at least one code section enables dynamically allocating said at least a portion of said reserved resources based on past and/or present network statistics.

14. The machine-readable storage according to claim 9, wherein said at least one code section enables utilizing unallocated portions of said reserved network resources for communicating one or more multimedia streams.

15. The machine-readable storage according to claim 14, wherein said at least one code section enables distributing said communicated one or more multimedia streams among said unallocated portions of said network resources.

16. The machine-readable storage according to claim 9, wherein said at least one code section enables allocating said at least a portion of said reserved resources to enable reliable communication of said administrative and/or control traffic when communicating one or more multimedia streams.

17. A system for communication, the system comprising:

one or more processors that enable;

reservation, via AVB, of resources in a network node; and

allocation of at least a portion of said reserved resources for administrative and/or control traffic to and/or from said network node.

18. The system according to claim 17, wherein said one or more processors enable assigning said administrative and/or control data a highest priority.

19. The system according to claim 18, wherein said priority is identified in a VLAN tag of an Ethernet frame comprising said administrative and/or control data.

20. The system according to claim 17, wherein said one or more processors enable allocation of said at least a portion of said reserved resources for each AVB stream registered in said network node.

21. The system according to claim 17, wherein said one or more processors enable dynamic allocation of said at least a portion of said reserved resources based on past and/or present network statistics.

22. The system according to claim 17, wherein said one or more processors enable utilization of unallocated portions of said reserved network resources for communicating one or more multimedia streams.

23. The system according to claim 22, wherein said one or more processors enable distribution of said communicated one or more multimedia streams among said unallocated portions of said network resources.

24. The system according to claim 17, wherein said one or more processors enable allocation of said at least a portion of said reserved resources to enable reliable communication of said administrative and/or control traffic when communicating one or more multimedia streams.
