Paper Abstract

Optical Burst Switching (OBS) provides statistical multiplexing capabilities at the optical layer with relaxed hardware requirements when compared to optical packet switching. Burst blocking probability of OBS networks is a very serious problem without efficient wavelength converter or optical buffer so that OBS is not available in the near future. We proposed a new switching architecture and technical implementation issues. The technical features of the proposed network are use of ring topology, one-way reservation, out-of-band transmission of the burst packet control signal, optical burst transmission unit, loss-free transmission of burst, small delay jitter, and dynamical intelligent wavelength add-drop multiplexer (DI-WADM) module. Our proposed switching architecture and technical implementation issues can make most use of both optic and electric technology and provide a good resolution of optical burst packet contention with our proposed access protocols. The implementation frameworks of the proposed network and node are simple.
