Abstract :
This paper presents an absolute service differentiation scheme for different architecture of an Asynchronous Optical Packet Switched (OPS) network. The performance of switching node has been assessed for different traffic load condition as well as for different percentage of high priority (HP) traffic. In order to provide service differentiation, in this study the wavelength domain has been explored extensively. An adaptive wavelength allocation (WA) algorithm is used, where the number of wavelengths reserved (L) for high priority (HP) traffic is adjusted. For guaranteed service provisioning to HP traffic an upper bound is provided on acceptable range of packet loss ratio (PLR) to keep the loss probability under control. The experienced packet loss ratio (PLR) in a node is measured for every interval, and L is adjusted based on measurements in two consecutive intervals.
