ABSTRACT
As day by day application grows internet requires large amount of bandwidth. Optical Burst Switching (OBS) is the next generation optical Internet with IP over WDM as the core architecture. It can achieve a balance between Optical Circuit Switching (OCS) and Optical Packet Switching (OPS). Optical network supports huge bandwidth and transmits data at an average rate of 50Tb/s. But we need to exploit the fiber’s huge bandwidth through WDM which is the current favorite multiplexing technology in Optical communication networks. OBS is a trusted mechanism used for optical switching. Optical burst switching has been positioned as a viable means of implementing optical communication efficiently. This review paper identifies potential threats to security in OBS networks. Solutions in each category are examined, and research directions are presented.
