摘要： A method of managing a communications system is disclosed. The method begins with the creation of a resource control block corresponding to a resource of the communications system. The communications system includes, for example, a processor and a resource coupled to the processor. The resource control block maintains information regarding the resource. The method also provides for the maintenance of the resource control block. The processor is configured to maintain the resource control block, and the resource control block is maintained by the processor in response to communications (e.g., a keep-alive message) between the processor and the resource. This embodiment can also include the creation of a processor resource control block corresponding to the processor that is created by the controller in response to a power-up message from the resource. The resource can be, for example, a hardware component of the communications system.

摘要： A method for restoring a virtual path, provisioned between a source and a target node, in a mesh optical network is described. The method, in one embodiment, forwards a resource request in the network to identify an alternate route. Each node identifies and allocates resources for failed virtual path and the virtual path is provisioned using these resources. The constant update of nodal topology by each node may provide a fast identification of nodes with required bandwidth for failed virtual path.

摘要： A method for restoring a virtual path, provisioned between a source and a target node, in a zoned mesh optical network is described. The method, in one embodiment, allocates a primary and a secondary physical path to the virtual path. The two physical paths are network element and link disjoint. In case of a failure in one physical path, the end nodes switch the virtual path to the other physical path.

The method, in one embodiment, allocates a primary and a secondary physical path to the virtual path. The two physical paths are node and link disjoint. In case of a failure on one physical path, the network switches the virtual path to the other physical path. The alternate path can be shared among various virtual paths during the restoration.

摘要： A method and apparatus for restoring a virtual path are disclosed. The method includes identifying an alternate physical path and determining whether the alternate physical path is able to support the virtual path by determining whether each node of the second subset of nodes has sufficient resources necessary to support the virtual path. The virtual path is over a physical path in an optical network, and the optical network includes a number of nodes. The physical path includes a first subset of nodes of the nodes. The alternate path includes a second subset of nodes of the nodes and is between a first node and a second node of the first subset of nodes.

摘要： A method for reserving resources for restoration of a failed virtual path in a mesh optical network is defined. The method in one embodiment, defines multiple classes of service for the virtual path by allocating certain path performance, path implementation and path restoration related attributes to the virtual path. Each class of service defines the relative restoration priority of the virtual path. In a case of a path failure, the class of service is used by each node, to determine how the virtual path will be restored. The higher class of service guarantees a maximum acceptable restoration time during a path failure.

摘要： A method is provided to allocate bandwidth from a first node to a second node in a optical network. The method begins by accepting a request from an end-user, who requests a virtual path between the first node and the second node. The first and second nodes are ones of a number of such nodes. Each one of the nodes is coupled to at least one other node by at least one of a number of optical links. The nodes and links form the optical network. The virtual path has a bandwidth requirement associated therewith. Next, the service provider determines an amount of bandwidth available between the first and the second nodes. The service provider then allocates at least a portion of the amount of bandwidth available between the first and second nodes equal to the bandwidth requirement, so long as the bandwidth requirement is not greater than the amount of bandwidth available between the first and second nodes.
