Abstract: With the explosive growth of the Internet, QoS provisioning becomes increasingly important in all-optical wavelength routing network. In this paper, we consider connection loss probability as QoS metrics and propose a wavelength allocation method to provide multiple QoS classes in terms of the connection loss probability. With our method, wavelengths are classified into two types of sets, dedicated wavelength sets and shared wavelength set, and connections are established using idle wavelengths within either set at each node. The performance of our proposed method depends on the capability of wavelength conversion and we also consider how the method is applied to a wavelength routing network with limited-range wavelength conversion capability. To evaluate the performance of our method at node in the network, we model the system with our method as a two-stage queueing system and calculate the connection loss probability of each class with equivalent random method (EQRM). Moreover, we evaluate the performance of the method for ring and mesh-torus networks by simulation. Numerical example show that the shared wavelength allocation method is effective regardless of network topology and network scalability.
