Near-future multimedia communications will require high-capacity networks employing optical WDM technology to simultaneously carry increasingly large numbers of broadband users. Fast and efficient restoration of network service after failure will be critical to maintaining customer satisfaction and ensuring business success.This paper discusses state-of-the-art software tools and algorithms developed by BTexact Technologies for automated design of such networks, planning of their restoration/resilience capacity, and calculating corresponding end-to-end service availability.The tools and underlying algorithms/models are largely technology independent, and may therefore be applied to a wide variety of scenarios. In this work, a generic network model representing an inter-city telecommunications network for a large European country is considered as a realistic test case.
