Abstract

This paper focuses on a scheme for resource provisioning control at nodes in the WDM backbone. Taking note of that allocation of wavelength is only for duration of the burst, and the allocations to connections can be less than a wavelength or bursts from different connections share the wavelength, we propose a resource reservation and allocation algorithm. Our strategy allows resource dynamically allocated among the virtual connections over the optical network. By doing this, the number of backbone nodes and competition for wavelengths are reduced. So the algorithm is a promising way to minimize blocking and provide better wavelength capacity utilization. Consequently, the number of required optical devices is reduced and the network cost is decreased. Furthermore, our algorithm is distributed; it can give high degree of flexibility. The effectiveness of this scheme in improving the performance of network is demonstrated through simulations.
