In this paper, the authors give an introduction to Optical Burst Switching (OBS) and compare it with other existing optical switching paradigms. They analyze and then compare performance models of a fast-adapting and centrally controlled form of Optical Circuit Switching (OCS) with a conservative form of Optical Burst Switching (OBS). They compare Optical Burst Switching with Optical Circuit Switching and Optical Packet Switching techniques. With recent advances in Wavelength Division Multiplexing (WDM) technology, the amount of raw bandwidth available in fiber links has increased by many orders of magnitude. Meanwhile, the rapid growth of Internet traffic requires high transmission rates beyond a conventional electronic router's capability.
