abstract

In order to solve the wavelength resource reserve collision problem in distributed wavelength assignment senario for PCE/GMPLS-based WSONs, a half-centralized wavelength assignment scheme has been proposed, which efficiently avoids the collision by adding several functions to PCE and doing some extensions to the GMPLS signaling. Simulation results show that the proposed scheme performs much better in decreasing total blocking probability than two traditional ones under various traffic conditions, especially when the traffic load is low while the arrival rate is high.
