Paper Abstract

A new scheme to mitigate the connection setup time overheads in distributed wavelength reservation schemes for WDM multi-fiber optical networks is proposed in this study. In this scheme, we consider the reconfiguration delay of switch fabric in distributed signaling protocols, which designated as signaling with switch fabric status (SWFS). Protocol realization selects and reserves the available wavelength that has the least switch fabric reconfiguration times along the path to shorten the connection establishment time. In this paper, we proposed four wavelength reservation schemes with SWFS for multi-fiber optical networks, which are S-FW-FF, S-FW-RF, S-RW-FF, and S-RW-RF. Simulation results indicate that schemes with SWFS have the shorter setup time, lower switching ratio as well as better blocking performance than those of without SWFS. Especially, the proposed schemes significantly reduce numbers of switch fabric that need to be reconfigured.
