Title
A model of service differentiation burst assembling and padding for improving transmission efficiency in OBS networks
Abstract
Service differentiation is an indispensable requirement for transmission in optical burst switching (OBS) networks, which can be based on offset-time, burst-length, or both, offset-time and burst-length. The offset time based approach sets a large offset time for high priority bursts and a small offset time for low priority bursts. Whereas, with burst length based approach, high priority bursts are short in size and low priority bursts are long in length. A combination of these two approaches promises to provide flexible service differentiation. The paper proposes a model of service differentiation burst assembling and padding, in which the assembly time threshold is set to reduce the end-to-end delay, but does not effect the burst length prediction accuracy; the length of generated bursts are flexibly adjusted based on feedbacked void size; and the high-priority burst with short length is padded by the lower priority data. Simulation results and analysis show that the proposed model is more efficient than previous similar models in terms of bandwidth utilization, byte loss, throughput fairness and estimation error.
