Optical burst switching (OBS) is a promising method for data transfer in photonic networks based on a Wavelength Division Multiplexing (WDM) technology. Transmission control protocol (TCP)-based applications generate the majority of data traffic in the Internet1 thus, understanding and improving the performance of TCP over OBS networks is critical. In this paper, we develop a novel burstdropping strategy to improve the quality of service provided by TCP over OBS networks. Our approach relies on random-segment dropping according to the capacity of a special optical component, called the optical virtual memory, which is used for buffering purposes within the optical switches. The core node predicts incipient congestion by computing the average blocking duration in the optical virtual memories. When this size exceeds a threshold, segments are randomly dropped. Simulation results show that the proposed method performs better than common techniques in terms of burst loss probability and transmission delay.

This paper presents an architecture for an all optical switching node. The architecture is suitable for optical packet and optical burst switching and provides appropriate contention resolution schemes and QoS guarantees. A concept, called virtual memory, is developed to allow controllable and reasonable periods for delaying optical traffics. Related to its implementation, several engineering issues are discussed, including the use of loopbased optical delay lines, fiber Bragg gratings, and limited number of signal amplifications. In particular, two implementations using optical flip-flop and laser neuron network based control units are analyzed. This paper also discusses the implementation and performance of an alloptical synchronizer that is able to synchronize arriving data units to be aligned on the clock signal associated with the beginning time of slots, in the node, with an acceptable error.
