Patent ID: 8009681

Claim:
A method for interworking a Resource Reservation Protocol (RSVP)-based external control plane protocol with an internal control plane protocol, comprising: given an external control plane protocol and an internal control plane protocol, performing a high-level mapping from an external control plane protocol message/field to an internal control plane protocol message/field at a near end of an internal domain, comprising: encapsulating through a message-by-message mapping the external control plane protocol message/field as data in the internal control plane protocol message/field, wherein the message-by-message mapping is limited only to points at which an action is necessary in the internal domain; and creating a trigger in the internal control plane protocol message/field operable for initiating a desired internal control plane action comprising establishing a connection responsive to the external control plane protocol message/field requiring internal control plane action; and processing the external control plane protocol message/field at a remote end of the internal domain.
