Abstract:
Growing competition between network operators, new characteristics of traffic as well as network survivability challenges result in evolution of the Internet transport infrastructure towards a converged transport layer, which provides bit-transport function to accommodate various upper layer services and applications. This transport infrastructure consists of various network elements, e.g. core IP/MPLS routers and optical switches. It provides basic transport modes, e.g. connection oriented circuit, connection oriented packet and connectionless packet modes, with complete SLA/QoS profiles. In order to achieve this converged transport infrastructure, several important functional components are need. This tutorial presents both the problem and solution to this converged infrastructure. It covers the major functional components, and gives a broad overview of the trends and technologies for IP/MPLS-Optical Internetworking. Network models for IP-optical interconnection are described together with discussion of multi-phased IP-over-Optical evolution. Benefits from the introduction of a control plane are presented along with an overview of key protocols and current standardization activities within this area. Alternative IP/MPLS-over-Optical deployment architectures, including a case study, are discussed. Challenges and approaches to IP/MPLS and optical restoration in next-generation optical networks are presented.

Intended Audience:
(1) General audience in the optical networking industry involved in the design and implementation of architectures and protocols for optical networks and IP-Optical integration.
(2) Researchers/students from academia and research labs interested in pursuing advanced research in the IP-Optical internetworking area and would like to gain an understanding of the fundamental state-of-the-art concepts in this area.
