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.
