Sytems and methods for multi-layer interworking

Abstract

Systems, modules, computer-readable mediums and methods for multi-layer interworking are provided. An identified traffic path is selected from one or more traffic paths. The identified traffic path is selected based on information indicative of traffic path parameter information associated with the identified traffic path relative to traffic path parameter information associated with the other traffic paths. A transport trail is identified from one or more transport trails. Whether the identified transport trail from one or more transport trails is suitable for assignment is determined. The determination is made based on information indicative of the transport trail parameter information associated with the identified transport trail relative to transport trail parameter information associated with the other transport trails. The selected identified traffic path is assigned to the identified transport trail if the identified transport trail is determined to be suitable for assignment.
