This paper introduces a centralized admission control mechanism, referred to as Threshold-based Blocking Differentiation (TBDijf), to differentiate the blocking probability experienced by various service classes in a circuit switched WDM network. The mechanism is based on multiple class-thresholds that indicate the minimum amount of capacity that must be available, prior to accommodating a request for a given service class. The performance of TBDiff is studied by means of an analytical framework and also an event-driven simulator. The results show a thorough matching of the analytical and simulation results and also demonstrate that high blocking differentiation among service classes can be obtained, without excessively increasing the overall (average) network blocking probability.In the turbo decoder, the current APP decoder utilizes the extrinsic value Le(uk) of the previous APP decoder as a priori value L(uk).
