Control Plane Measurement Based Dynamic Offset Time Algorithm in Optical Burst Switching Networks

A dynamic offset time assignment algorithm based on the measurement of cross traffic on control plane is proposed. This algorithm uses probe burst,s drop ratio as observing variable to determine the core node,s background traffic and assigns offset time dynamically based on the measured result. Analysis and simulation show that this algorithm can get moderate offset time under target Insufficient Offset Time (IOT) drop ratio,s restriction and obtain tradeoff between end to end delay and IOT ratio.
