Methods and systems for interworking RSVP-based external control plane protocols with internal control plane protocols

摘要

The present invention provides improved methods and systems for interworking Resource Reservation Protocol (RSVP)-based external control plane protocols with internal control plane protocols, such as Optical Signaling and Routing Protocol (OSRP). The present invention utilizes only a high-level mapping in which a trigger is created in the internal control plane protocol to initiate the desired internal control plane action or vice versa. The external control plane protocol messages and fields are encapsulated as data in the internal control plane messages and fields and are processed only at the remote end of the internal domain. By encapsulating the entirety or parts of the external control plane protocol messages and fields ensures that necessary information is carried from an ingress border node to an egress border node. At the egress border node, the encapsulated external control plane protocol messages and fields are mapped back to the external control plane protocol, without having to make changes to the internal control plane protocol or perform processing at intermediate nodes.
