Abstract

We address the control plane architecture of how to provide advance quality of service (QoS) in optical burst switching networks based on dynamic wavelength assignment. Unlike existing QoS guaranteeing scheme, such as buffer-based and offset-time based scheme, our proposed dynamic virtual lambda partitioning (DVLP) scheme does not mandate any buffer or extra offset time, but can achieve better QoS performance. This new DVLP scheme shares wavelength resources based on several different priority of classes in an efficient and QoS guaranteed manner. Also, hysteresis characteristic of DVLP is placed on robustness, meaning that each traffic classes with blocking probability conforming to the target value continue to receive the required QoS, despite the presence of misbehaving packets such as bursty arrival traffics. The performance results show that the proposed scheme effectively guarantees a target blocking probability of each traffic classes both in Poisson and Self-similar traffic environment.
