Abstract

In the past few years we have experienced dramatic changes in the architecture, features and functionality of telecommunication networks. The changes came along with huge increases in the types and complexity of new services and in the volume of traffic carried by these telecommunication networks. As new technologies have emerged and replaced the old ones more networks need to be planned and built. This growing demand for effective and efficient telecommunication network planning, adapted to the new technologies and new services, is the driver for the work presented here. Along with Synchronous Digital Hierarchy (SDH) technology, resilient ring network solutions were developed. These network architectures are well suited to the new SDH concepts and satisfy the growing demand for high resilience and easy network management. It has been essential, in terms of network planning, to understand the features, characteristics and performance of these resilient ring architectures. We explore the characteristics of these network solutions, metricate alternative solutions and develop optimised implementation. In this thesis SDH technology principles and network solutions are discussed. A framework that allows an elaboration of the traffic modelling and analysis process is presented. Properties of resilient ring architectures, in terms of capacity performance, are then examined. Results about the effectivenes and efficiency of these ring architectures are derived. A metrication framework for the evaluation of transport network solutions is proposed and factors that affect the resilience of ring based architectures are examined. Finally, novel algorithms for the planning of ring networks are proposed and their efficiency is examined.
