System and method of automatically configuring I-SIDs in GMPLS controlled ethernet provider backbone bridged networks

摘要

A system and method of automatically configuring a Service Instance Identifier (I-SID) in a Generalized Multiprotocol Label Switching (GMPLS) controlled network. The method begins by identifying a specific I-SID for a specific service in the GMPLS controlled network. Next, the identified I-SID is automatically configured within a Backbone Edge Bridge (BEB) with a Resource Reservation Protocol-Traffic Engineering (RSVP-TE) extension. The automatic configuration may be implemented by several different embodiments. In one embodiment, the I-SID may be carried in a SESSION_ATTRIBUTE object. In another embodiment, the I-SID may be mapped to a Short Call ID field in a Session object. Alternatively, the I-SID may be carried in an Endpoint ID Type-Length-Value (TLV). The I-SID may also be carried in a new TLV in a LSP_ATTRIBUTES or CALL_ATTRIBUTES object.

1. A method of automatically configuring a Service Instance Identifier, I-SID, in a Generalized Multiprotocol Label Switching, GMPLS, controlled network, the method comprising the steps of:
identifying a specific I-SID for a specific service in the GMPLS controlled network; and automatically configuring the identified I-SID within a Backbone Edge Bridge, BEB, with a Resource Reservation Protocol-Traffic Engineering, RSVP-TE, extension, wherein the step of automatically configuring the identified I-SID includes one of:
carrying the I-SID in a SESSION_ATTRIBUTE object,mapping the I-SID to a Short Call ID field in a session object,carrying the I-SID in an Endpoint ID Type-Length-Value, TLV, of the session object, andcarrying the I-SID in a new TLV in a LSP_ATTRIBUTES or CALL_ATTRIBUTES object.
