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.
