Delay models for different UNI signalling implementations in the context of IST Project MUPBED

The concept of intelligent optical networks (ION) nowadays is becoming reality. The GMPLS protocol suite of IETF, the ASON recommendation of ITU-T, and the reference points defined by OIF are existing standards. Real test beds, using these architectures and technologies across Europe and worldwide, are studied and improved. Today, the interaction issues (requirements, functions, protocols and interfaces) between the IP/MLPS client layer and the ASON/GMPLS server layer are being comprehensively researched. In this paper, delay models for simple implementation options of user to network interface (UNI) signalling are evaluated in the context of the EU project MUPBED.
