Abstract

A method for creating a path for data transmission in a network determines the reliability rate of each of a plurality of network elements, and selects a network element with a reliability ability rate above a threshold value. The method enables a path including the selected network element for data transmission.

Claims

1. A method for creating a path for data transmission in a network, comprising:

determining a reliability rate of each of a plurality of network elements;

selecting a network element with a reliability rate above a threshold value; and

enabling a path comprising said selected network element for data transmission.

2. The method according to claim 1, wherein constraints are placed on network elements with a reliability rate below a threshold value.

3. The method according to claim 1, wherein the created path comprises network elements with reliability rates satisfying criteria of a Class of Service (CoS).

4. The method according to claim 1, further comprising storing alarms indicating events affecting a network element'"'"'s handling of data in a memory device.

5. The method according to claim 4, further comprising providing the stored alarms with information as to the nature and severity of the event affecting the network element'"'"'s handling of data.

6. The method according to claim 4, further comprising determining the reliability rate in dependence of the alarms associated with a network element.

7. The method according to claim 1, further comprising determining the reliability rate in dependence of events affecting a data handling of a network element.

8. The method according to claim 1, wherein along with the reliability rate, at least one of the following criteria is used to select the network element:

source and destination of the path,

bandwidth requirements within the path,

bandwidth availability within the path,

a maximum number of hops to be included in the path,

administrative groups resource affinities within the path,

delay and jitter between a plurality of network elements within the path,

connectivity between a plurality of network elements within the path.

9. The method according to claim 1, wherein the creation of the path is executed by a network management system (NMS).

10. The method according to claim 1, wherein the path is created in an IP network.

11. The method according to claim 1, wherein the path is created in an MPLS network.

12. The method according to claim 11, wherein the path comprises a Label Switch Path (LSP).

13. The method according to claim 1, wherein the network elements comprise switches.

14. The method according to claim 1, wherein the network elements comprise links.

15. The method according to claim 1, wherein the network elements comprise routers.

16. The method according to claim 15, wherein the routers comprise Label Edge Routers.

17. The method according to claim 15, wherein the routers comprise Label Switch Routers.
