摘要：Routing and Wavelength Assignment (RWA) is one of the key tasks for the optical network, due to itsinformation transparency and wavelength reuse characteristics.This paper presents heuristic algorithm that can be used for routing and wavelength assignment for All-OpticalWDM networks under dynamic arising of calls.We have considered All-Optical Networks (AON) without wavelength conversion and dynamic RWA schemewhich is based on the distributed Dijkstra's routing algorithm and first-fit wavelength reservation with a set of 64wavelengths in random topology and for 500 calls the Call Blocking Ratio (CBR) is 0.55 and simulation time is 5sec.For different arrival of calls the performance is analysed in terms of blocking probability as well as the simulationtime of the heuristic algorithm and has been studied through simulation
