Abstract

The performance analysis of distributed connection management for WDM optical networks with different nodal degrees is proposed in this study. In our previous study, we proposed a distributed wavelength reservation scheme with switch fabrics status. We consider the reconfiguration information of switch fabrics in the signaling protocol, which designated as the signaling with switch fabric status (SWFS). Distributed reservation algorithms will reserve the wavelength with minimum of reconfiguration times of OXCs along the route to shorten the connection establishment time. In this paper, we analysis the reservation schemes with or without SWFS for FAXC or FBXC modes, especially the performance with different nodal degrees. The simulation results indicate that schemes with SWFS have the shorter setup time, lower switching ratio than those without SWFS. The schemes for FBXC mode have the better blocking performance than those for FAXC mode. The switching ratio, the blocking probability and connection setup time decrease with the increase of nodal degrees for S-RM. The increase of the nodal degree from 2 to 3 and from 6 to 7 leads to higher nodal degree gains.
