Abstract

Optical burst switching (OBS) is a new optical switching technology emerging in recent years. Combining the advantages of wavelengthrouting and optical packet switching, OBS is a relatively ideal interim scheme for switching networks in near future. This article introduces the basic principle of OBS in detail, and discusses the key technologies for OBS, such as the setting of offset time and the scheduling of data channel. Finally it summarizes the characteristics of OBS and some problems that still need to be solved.
