Burst Assembly with EN Differentiation in OBS under Unsymmetrical Traffic

摘要

On account of the glary future of Optical Burst Switching (OBS) network and the abundant Transmission Control Protocol (TCP) traffic, study of TCP combing OBS are prevail in the recent years. In this paper, we address the issue of assembly algorithm in OBS network based on unsymmetrical TCP traffic. The Optimal Maximum Assembly Length (OMAL) in Max-Time-Min-Max-Length Assembly Algorithm is studied in this paper and an assembly algorithm with edge node differentiation based on unsymmetrical traffic is presented by investigating the feature of TCP flow. We also propose client's Average Download Rate (ADR) as an evaluation standard and the simulation results show that the Assembly Algorithm with EN Differentiation will improve client's ADR a lot.
