Burst circulating threat in optical burst switched networks

Optical network is a high speed network thus reduce the huge bandwidth demands and increase the internet users. Optical burst switched network is an optical networking technique that allows dynamic sub wavelength. OBS is viewed as compromise the optical packet switching and optical circuit switching networks. OBS networks suffer from various security vulnerabilities. This paper propose a security threat named as Burst Circulating attack for OBS networks and provide defective mechanism for this attack. The ns2 simulator with modified nOBS patch is used simulate and verify the security parameter.
