A Simple Analytical Model for the Calculation of Packet Blocking Probability in an Optical Packet Switching Netw

Optical packet switching is a promising all-optical network technology for future large-scale networks, due to good resource utilization and the ability to handle high data rates in a cost-efficient way. In this paper we investigate the performance of an optical packet switching network, in respect of the packet blocking probability. The network supports the wavelength conversion technique, in order to reduce packet losses. We derive an analytical model for the calculation of blocking probability, based on the reduced load approximation method. The demonstration of the accuracy of the proposed analysis is realized by comparing the analytical results with that of simulation; the results found to be quite satisfactory.
