Abstract

Claims (42)

1. A method for accumulating virtual concatenation group bandwidth data at a node, comprising:

(a) determining, at the node, at least one elementary path of which a virtual concatenation group is composed;

(b) determining, for each elementary path, elementary path data comprising an elementary path bandwidth value;

(c) computing a virtual concatenation group bandwidth value for said virtual concatenation group using said elementary path bandwidth values; and

(d) accumulating virtual concatenation group bandwidth values for said virtual concatenation group by periodically repeating steps (a)-(c).

2. The method of claim 1 , wherein determining said at least one elementary path comprises:

identifying said virtual concatenation group; and

accessing said virtual concatenation group to identify said at least one elementary path.

3. The method of claim 2 , wherein said identifying said virtual concatenation group is performed on at least one of a virtual concatenation group originating node and a virtual concatenation group terminating node.

4. The method of claim 2 , wherein said at least one elementary path comprises at least one active elementary path.

5. The method of claim 1 , wherein said determination of elementary path data associated with said at least one elementary path comprises:

identifying, for each of said at least one elementary path, an elementary path type associated with said at least one elementary path; and

determining, for each of said at least one elementary path, said elementary path bandwidth value using said elementary path type.

6. The method of claim 1 , wherein each of said at least one elementary path substantially conforms to at least one of a VT-1.5, VT-2, VT-3, VT-6, STS1, STS3, TU-11, TU-12, TU-2, TU-3, AU-3, and AU-4.

7. The method of claim 1 , wherein said accumulation of said virtual concatenation group bandwidth values is performed by periodically repeating steps (a)-(c) at least once each minute.

8. The method of claim 1 , further comprising:

integrating at least a portion of said virtual concatenation group bandwidth values for computing at least one total virtual concatenation group bandwidth value.

9. The method of claim 1 , wherein said virtual concatenation group bandwidth values are accumulated in at least one virtual concatenation group bandwidth data bin.

10. The method of claim 9 , wherein said at least one virtual concatenation group bandwidth data bin comprises virtual concatenation group bandwidth values collected within at least one of a fifteen minute period and a twenty-four hour period.

11. The method of claim 9 , wherein said at least one virtual concatenation group bandwidth data bin is stored locally.

12. The method of claim 9 , wherein at least a portion of said at least one virtual concatenation group bandwidth data bin is transmitted towards at least one external system.

13. The method of claim 12 , wherein said at least one external system is at least one of an element management system, a network management system, a service management system, and a billing system.

14. The method of claim 12 , further comprising:

receiving, by said at least one external system, at least a portion of said at least one virtual concatenation group bandwidth data bin; and

computing at least one bill using said at least a portion of said at least one virtual concatenation group bandwidth data bin.

15. An apparatus, comprising:

means for determining at least one elementary path of which a virtual concatenation group is composed;

means for determining, for each elementary path, elementary path data comprising an elementary path bandwidth value;

means for computing a virtual concatenation group bandwidth value for said virtual concatenation group using said elementary path bandwidth values; and

means for accumulating virtual concatenation group bandwidth values for said virtual concatenation group by periodically computing said virtual concatenation group bandwidth value for said virtual concatenation group.

16. The apparatus of claim 15 , wherein said means for determining at least one elementary path comprises:

means for identifying said virtual concatenation group; and

means for accessing said virtual concatenation group to identify said at least one elementary path.

17. The apparatus of claim 15 , wherein said means for determining elementary path data associated with said at least one elementary path comprises:

means for identifying, for each of said at least one elementary path, an elementary path type associated with said at least one elementary path; and

means for determining, for each of said at least one elementary path, said elementary path bandwidth value using said elementary path type.

18. The apparatus of claim 15 , wherein said means for accumulating virtual concatenation group bandwidth values for said virtual concatenation group accumulates said virtual concatenation group bandwidth values in at least one virtual concatenation group bandwidth data bin.

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

(a) determining at least one elementary path of which a virtual concatenation group is composed;

(b) determining, for each elementary path, elementary path data comprising an elementary path bandwidth value;

(c) computing a virtual concatenation group bandwidth value for said virtual concatenation group using said elementary path bandwidth values; and

(d) accumulating virtual concatenation group bandwidth values for said virtual concatenation group by periodically repeating steps (a)-(c).
