ROBS: A novel architecture of Reliable Optical Burst Switching with congestion control

Abstract

In this paper, we propose a novel improved architecture of Optical Burst-Switched Networks, called Reliable Optical Burst Switching (ROBS), which introduces congestion control and retransmission mechanisms of TCP to OBS layer. Design issues of edge and core nodes for ROBS networks are both demonstrated. Part of its function has been implemented on ns-2 platform and its performance are evaluated by simulation.
