As the purpose of DSM-CC session control is to associate resources for the same service, the actual protocols used for the allocation/de-allocation of each resource are outside the scope of DSM-CC. The DSM-CC AddResource operation is used just to bind (or register) resources to a session. The actual allocation of resource should be deferred to resource-specific protocols such as Q.2931 and RSVP. Resource descriptors are used DSM-CC U-N to describe the connections required. These resources are extendible to other networks than presently specified in the DSM-CC U-N specification.
