摘 要：One of the major challenges for optical network operators is related to realizing profitable networks that preserve the overall satisfaction of their end *** necessitates ensuring a controlled network resource usage while decreasing connection blocking ***,optical networks are witnessing the introduction of an increasing number of new services,each having different *** such,the evolution towards resource efficient connection setup management strategies that provide differentiated call-blocking probability becomes *** on the previous observation,we propose in this paper a novel connection setup management *** latter aims to differentiate the blocking probability among different classes of lightpath requests,while avoiding the starvation of the lower class *** main idea behind our proposal is to privilige higher class lightpaths via preemption and to protect the lower class lightpaths through *** this manner,the proposed strategy serves the double objective of minimizing the overall connection blocking probability and of realizing Quality of Service（QoS） *** previous claim is asserted through our simulation results that gauge the main benefits behind our proposed connection setup *** simulation results drawn from the National Science Foundation Network（NSFNET） and the European Optical Network（EON） show that the proposed strategy achieves both differentiated and low blocking probabilities.
