Multi-Protocol Label Switch (MPLS) and Generalized MPLS (GMPLS) are key technologies for next-generation IP backbone network. GMPLS Technologies: Broadband Backbone Networks and Systems addresses the basic concepts, network architecture, protocols, and traffic engineering needed to operate MPLS and GMPLS networks. This volume covers MPLS applications, details IP router structures, illustrates GMPLS, and explores the important studies on traffic engineering in GMPLS Networks. Network engineers design equipment and network service engineers can reference this book to understand the techniques necessary to build the MPLS / GMPLS-based network. Features Address basic concepts, network architecture, protocols, and traffic engineering needed to operate MPLS and GMPLS networks Covers the basics of connection-oriented networks including TCP / IP, flow control mechanisms, and the ATM protocol Analyzes MPLS issues and applications, such as label switched path (LSP) and VPN Highlights IP router structures, examining the data path technology functions - switch architecture, packet scheduling, and forwarding engine Exploring multi-layer traffic engineering, survivable networks, and optical network wavelength-routed Demonstrate GMPLS-based routers
