Adaptive reliable optical burst switching

This paper presents the adaptive reliable optical burst switching (AR-OBS) paradigm that employs two-way reservation, and edge burst aggregation to guarantee deterministic data latency and loss rate under a distributed control plane. AR-OBS employs the adaptive robust fast optical reservation protocol (A-RFORP) to provide adaptive blocking recovery control with offset delay adjusted to take into account of blocking recovery delay. And delayed reservation is employed to ensure wavelengths are reserved just in time before the data bursts arrive to maximize the wavelength utilization. Performance of AR-OBS is discussed in terms of burst reservation delay, burst aggregation overflow probability, burst reservation blocking probability and wavelength utilization. It is found that performance of AR-OBS is compared favorably with other OBS schemes based on two-way reservation and edge burst aggregation.
