Abstract

Claims (40)

1. A method for assigning at least one virtual concatenation group member to a virtual concatenation group at a terminating node, said terminating node comprising a processor and a memory, said method comprising:

receiving, at said terminating node, originating configuration information comprising at least one assignment parameter and at least one originating capability parameter;

identifying terminating configuration information associated with said terminating node, said terminating configuration information comprising at least one terminating capability parameter;

comparing said at least one originating capability parameter to said at least one terminating capability parameter; and

assigning said at least one virtual concatenation group member to said virtual concatenation group on said terminating node using said at least one assignment parameter to form at least one member assignment, said assigning performed in response to a determination that said at least one originating capability parameter and said at least one terminating capability parameter are compatible.

2. The method of claim 1 , further comprising:

assigning said at least one virtual concatenation group member to said virtual concatenation group on an originating node using said at least one assignment parameter; and

establishing at least one channel between said originating node and said terminating node for said at least one virtual concatenation group member,

wherein said at least one channel conveys said originating configuration information from said originating node to said terminating node for said at least one virtual concatenation group member.

3. The method of claim 2 , wherein said at least one channel comprises at least one of at least one unidirectional channel and at least one bidirectional channel.

4. The method of claim 2 , wherein said at least one channel comprises at least one of at least one in-band channel and at least one out-of-band channel.

5. The method of claim 4 , wherein at least one of said at least one in-band channel is implemented using at least one unused bit position in a virtual concatenation group member overhead portion associated with at least one of said at least one virtual concatenation group member.

6. The method of claim 1 , wherein said assigning is performed in a manner tending to maximize a capacity available for transporting at least one service signal using said at least one virtual concatenation group member.

7. The method of claim 1 , wherein said at least one assignment parameter comprises at least one of an originating node identifier, a terminating node identifier, a virtual concatenation group identifier, and a virtual concatenation group member identifier.

8. The method of claim 1 , wherein said originating configuration information further comprises at least one originating constraint and said terminating configuration information further comprises at least one terminating constraint.

9. The method of claim 8 , wherein said assigning is performed in a manner tending to satisfy said at least one originating constraint and said at least one terminating constraint.

10. The method of claim 1 , further comprising:

modifying said at least one member assignment in response to a change in at least one of said originating configuration information and said terminating configuration information.

11. A computer readable storage medium storing software program, that, when executed by a computer, causes the computer to perform a method comprising:

receiving originating configuration information comprising at least one assignment parameter and at least one originating capability parameter;

identifying terminating configuration information associated with a terminating node, said terminating configuration information comprising at least one terminating capability parameter;

comparing said at least one originating capability parameter to said at least one terminating capability parameter; and

assigning said at least one virtual concatenation group member to said virtual concatenation group on said terminating node using said at least one assignment parameter to form at least one member assignment, said assigning performed in response to a determination that said at least one originating capability parameter and said at least one terminating capability parameter are compatible.

12. The computer readable storage medium of claim 11 , further comprising:

assigning said at least one virtual concatenation group member to said virtual concatenation group on an originating node using said at least one assignment parameter; and

establishing at least one channel between said originating node and said terminating node for said at least one virtual concatenation group member,

wherein said at least one channel conveys said originating configuration information from said originating node to said terminating node for said at least one virtual concatenation group member.

13. The computer readable storage medium of claim 12 , wherein said at least one channel comprises at least one of at least one unidirectional channel and at least one bidirectional channel.

14. The computer readable storage medium of claim 12 , wherein said at least one channel comprises at least one of at least one in-band channel and at least one out-of-band channel.

15. The computer readable storage medium of claim 14 , wherein at least one of said at least one in-band channel is implemented using at least one unused bit position in a virtual concatenation group member overhead portion associated with at least one of said at least one virtual concatenation group member.

16. The computer readable storage medium of claim 11 , wherein said assigning is performed in a manner tending to maximize a capacity available for transporting at least one service signal using said at least one virtual concatenation group member.

17. The computer readable storage medium of claim 11 , wherein said at least one assignment parameter comprises at least one of an originating node identifier, a terminating node identifier, a virtual concatenation group identifier, and a virtual concatenation group member identifier.

18. The computer readable storage medium of claim 11 , wherein said originating configuration information further comprises at least one originating constraint and said terminating configuration information further comprises at least one terminating constraint.

19. The computer readable storage medium of claim 11 , further comprising:

modifying said at least one member assignment in response to a change in at least one of said originating configuration information and said terminating configuration information.

20. An apparatus for assigning at least one virtual concatenation group member to a virtual concatenation group at a terminating node, comprising:

means for receiving originating configuration information comprising at least one assignment parameter and at least one originating capability parameter;

means for identifying terminating configuration information associated with said terminating node, said terminating configuration information comprising at least one terminating capability parameter;

means for comparing said at least one originating capability parameter to said at least one terminating capability parameter; and

means for assigning said at least one virtual concatenation group member to said virtual concatenation group on said terminating node using said at least one assignment parameter to form at least one member assignment, said assigning performed in response to a determination that said at least one originating capability parameter and said at least one terminating capability parameter are compatible.
