The next-generation dynamically-reconfigurable intelligent GMPLS-based WDM optical networks are expected to operate at extremely high data rates (40 Gbps or beyond) and will be used to carry voice, data, and various other multimedia applications. In these networks a signalling protocol (such as RSVP-TE), which is used to dynamically set up light-paths, should not only be fast and efficient, but must also be scalable and should try to maximize the number of accepted connections at an acceptable level of control overhead. In this paper, the authors propose a fast and efficient Segmented Signalling Protocol (SSP) based on a novel concept of Intermediate Destinations (IDs), for wavelength reservation in GMPLS/WDM optical networks.
