All-optical networks (AON) based on optical burst switching (OBS) are rapidly becoming the ultimate backbone network solution for next (future) generation networks because of their potential ultra high bandwidth capacities both at transmission and switching levels. The OBS switching paradigm was conceptualized and ultimately designed using the good features of both optical circuit switching (OCS ) and optical packet switching (OPS) and thus provides improvements over wavelength routing in terms of bandwidth efficiency, at the same time eliminating the need for huge buffers at the network edges as well as optical –to- electronic conversions and vice-versa of the data bursts at the core (switching) nodes. With such networks end to end light channels will transmit users data , transparently i.e. without being aware of its bit rate, modulation format as well as network protocol thus enhancing capacity, flexibility and scalability of the network. A buffer less /limited buffered lead OBS network would mean high contention and blocking, hence to guarantee and end-to-end consistent QoS in would require that the resources are properly managed. Effective management of both control and data planes is a key issue in this regard. Thus in this paper, we propose and analyse a partial distributed resource management scheme for OBS networks. We describe the concept, followed by routing and wavelength selection procedures.
