Abstract—In this paper, we consider the problem of routing and wavelength assignment (RWA) in all-optical networks, where signals propagate in the optical domain (with no electrical regen- eration) from end-to-end. In such networks, physical impairments are an issue and can cause calls to be blocked if a minimum Quality of Transmission (QoT) measured in terms of bit-error rate (BER) cannot be guaranteed for all calls, at all times. We focus on the routing component of RWA to incorporate QoT: we propose a novel RWA algorithm that finds a route based on both the network utilization and the physical impairments experienced over the tentative route. Our algorithm is fully decentralized and is shown,using simulations to perform better than previously proposed algorithms on a regional-sized network. I. I NTRODUCTION All-optical networks have emerged,as a promising solution to satisfy society’s dramatically increasing network throughput demands. Their appeal is accelerating due to recent devel- opments in optical signal processing functions (e.g., am- plification, filtering, and dispersion compensation) for fiber communication systems, and novel routing techniques and switching node architectures. Deploying all-optical or translu- cent networks is promising yet also quite challenging as many new,problems,must be anticipated as discussed in [1]‐[3]. One difficulty in designing routing protocols is to determine |
