TE-SIP server design for a SIP-over-MPLS based network

The next generation communication systems will provide multimedia services and will need to support high quality of service in a more flexible and intelligent manner than previous generations. In this paper, a network based on SIP (session initiation protocol) over MPLS (multi-protocol label switching) is proposed. A network architecture that adopts the SIP protocol as signaling to set up a call and MPLS as a core network forwarding mechanism is identified. A traffic engineering (TE)-SIP server is proposed, as part of a network architecture that will use a SIP session to provide a TE request for a SIP client. TE-server signaling mechanism and RSVP-TE LSP set-up are also discussed.
