Abstract

A method includes automatically detecting an association between members based on their relationship to one another; sharing topology and cluster information between the members; and determining roles for each member, based on the topology and cluster information and rules, wherein the roles are used to automatically provision at least one resource on each member, without user intervention. A method of configuring network devices sharing a pool of available resources is also described, wherein the network devices have management connectivity between one another through a plurality of point-to-point connections. The method includes, after a point-to-point connection in the management connectivity is formed based on cabling of associated network devices, determining a resource index number for each of the associated network devices; and uniquely assigning the resources from the pool to each of the network devices based on their respective resource index number.

First claim

What is claimed is:

1. A method of configuring members of a cluster of network equipment, the method comprising:
automatically detecting an association between the members based on their relationship to one another;
sharing topology and cluster information between the members;
determining roles for each member, based on the topology and cluster information and rules; and
automatically provisioning at least one resource on each member based on a determined role, without user intervention, wherein the at least one resource comprises an assigned wavelength that is automatically assigned based on a determined role of each member.

2. The method of claim 1 , wherein each member is a network device that is physically separate from other members and includes management connectivity to the other members through one or more point-to-point connections.

3. The method of claim 1 , wherein each member is a photonic device.

4. The method of claim 1 , wherein the association is based on management connectivity in the cluster, and the management connectivity comprising a plurality of point-to-point connections.

5. The method of claim 1 , wherein the automatically detecting is performed over available interfaces configured to determine the topology.

6. The method of claim 1 , wherein the cluster has a linear topology, and the determining the roles comprises a first member taking a lead role and all other members self-organizing in an order determined by connectivity to the first member.

7. The method of claim 1 , wherein the determining the roles comprises determining a lead role for one of the members based on a trigger, and all other members self-organizing in an order determined by connectivity to the member determined to have the lead role.

8. The method of claim 1 , wherein the cluster has a ring topology, and the determining the roles comprises determining a lead role for one of the members based on a trigger and all other members self-organizing in an order determined by connectivity to the member determined to have the lead role.

9. The method of claim 1 , wherein the cluster has a ring topology with an extension, and the determining the roles comprises a member connected to the extension taking a lead role and all other members self-organizing in an order determined by connectivity to the member determined to have the lead role.

10. The method of claim 1 , wherein the cluster has a ring topology with a spur, and determining the roles comprises determining a lead role for one of the members of the ring topology based on a trigger, and all other members in the ring topology self-organizing in an order determined by connectivity to the member determined to have the lead role.

11. The method of claim 1 , wherein the cluster has two connected ring topologies, and determining the roles comprises determining a lead role for one of the members of each ring and all other members, in each ring, self-organizing in an order determined by connectivity to the member determined to have the lead role.

12. The method of claim 3 , wherein the assigned wavelength for each member is used for fiber cabling to one of a multiplexer and a de-multiplexer.

13. A network device configured to operate in a cluster with a plurality of network devices, the network device comprising:
at least two management interfaces; and
processing circuitry configured to
automatically detect an association between the plurality of network devices based on connectivity of the at least two management interfaces,
share topology and cluster information between the plurality of network devices,
determine a role, based on the topology and cluster information and rules, and
automatically provision at least one resource on each member based on a determined role, without user intervention, wherein the at least one resource comprises an assigned wavelength that is automatically assigned based on a determined role of each member.

14. The network device of claim 13 , wherein the network device is physically separate from the plurality of network devices, with management connectivity to the plurality of network devices through one or more point-to-point connections.

15. The network device of claim 13 , wherein the network device is a photonic device and the automatically provisioned at least one resource is an assigned wavelength.

16. The network device of claim 15 , wherein the assigned wavelength for the network device is used for fiber cabling to one of a multiplexer and a de-multiplexer.
