Recent developments in communication technology contributed to the growth of network traffic exponentially. Cost per bit has to necessarily suffer an inverse trend, posing several challenges to network operators. Optical transport networks are no exception to this. On one hand, they have to keep up with the expectations of data speed, volume, and growth at the agreed quality-of-service (QoS), while on the other hand, a steep downward trend of the cost per bit is a matter of concern. Thus, the proper selection of network architecture, technology, resiliency schemes, and traffic handling contributes to the total cost of ownership (TCO). In this context, this chapter looks into the network architectures, including the optical transport network (OTN) switch (both traditional and universal), resiliency schemes (protection and restoration), flexible-rate line interfaces, and an overall strategy of handover in between metro and core networks. A design framework is also described and used to support the case studies reported in this chapter.

Next Generation Networks (NGN) provide ubiquitous connectivity with pervasive accessibility to service, application, content and information. NGN will bring tremendous advantages to companies and individuals, in terms of access to information, education and knowledge, efficiency, dematerialisation and new user experiences. Next Generation Networks: Perspectives and Potentials explores the potentials of NGN and provides an outlook of future services for the end users and opportunities for the traditional network operators and new players. It creates a framework to aid the understanding of NGN, exploring the strategic development and practical deployment of NGN. This book provides a complete and comprehensive picture of the future directions, substantial benefits, issues, applications and services for NGN. Offers an in-depth exploration of NGN covering both basic and advanced concepts Examines critical issues with the implementation of NGN Covers NGN technology, architecture, transport, services, and evolution and standardization. Written by industry experts focusing on the business opportunities of NGN with chapters on NGN standardization, development and corporate responsibility Next Generation Networks is ideal for network operators, equipment vendors, researchers, Telecoms regulators and engineers working in next generation networking. It will also be of interest to graduate students on electrical engineering and computer science programmes with a focus on networks.
