Abstract: A method and apparatus for generic support of frame relay services in a communications network is presented. This is accomplished by defining a bit field that indicates whether or not particular functions or services (including frame relay services) are supported by a particular node or other network component. The bit field for each component within the communications network is communicated to the network manager, which stores the bit fields for each component within a database. The database is then utilized to perform network management functions, as it informs the network manager whether a particular service/feature is available on the network component to which the bit field corresponds.

Abstract: A method and system for selecting ring paths in service provisioning on optical networks including a plurality of interconnected rings. The method includes: receiving a request to provision a service between a first end point and a second end point in the optical network; identifying a plurality of possible ring paths between the first and second end points; validating a bandwidth of each ring path, including validating bandwidths of bandwidth bottlenecks in each ring path; selecting a path from the validated ring paths; and provisioning the service on the selected path. The system utilizes a path engine on a network management server that knows about the bandwidth allocation in the entire network and implements the method. The resources of the optical network used by the provisioned service is thus minimized.
