The optical burst switching (OBS) based metro network is proposed to bridge the 'metro gap' between high performance core and LAN (local area network). Many media access protocols (MAC) have been suggested in literature for OBS based ring networks. This paper proposes a new MAC protocol for wavelength division multiplexing (WDM) based OBS metro ring(More)
DQOBSR (Distributed Queue Optical Burst Switched Ring) is a medium access protocol for wavelength division multiplexing based optical burst switched metro ring network. It is a slotted, distributed queue access protocol with fixed bus structure and simple wavelength assignment. The protocol provides zero blocking with acceptable access delays. However, the(More)
Optical Burst Switching (OBS) network is emerging as a promising technology for next generation optical internet due to its suitability to carry bursty traffic, adapting to the technological constraints of all optical networks. A significant issue for next-generation networks is the ability to support a wide range of services for different types of(More)
