Service providers can turn to numerous sources that describe technologies used in MPLS networks, such as QoS, Traffic Engineering (TE), and VPN; however there is no single resource that illustrates how to actually design a network that benefits from the latest technologies, and combines them optimally for a specific environment. Definitive MPLS Network Designs fills this void by providing a series of design studies showing how to combine key techniques and technologies at the heart of IP/MPLS networks in line with real-life network best practices. The book starts with a technology refresher for each of the technologies involved in the design studies, including VPNs, TE, QoS, multicast, pseudowires, network recovery, and IPv6. Following this overview are detailed design studies, each based on a set of characteristics and objectives common to a profile of networks deploying MPLS. The book contains a design study for an Inter-eXchange Carrier (IXC), for a National Telco, for a Global Service Provider, and for an enterprise. The authors develop each design study in a consistent manner, starting with a description of the network environment and supported services. They then identify the objectives which influenced the design. Each design study then details all aspects of the network design using the latest MPLS technologies. Finally, a number of lessons which can be drawn from the design study are pointed out, allowing readers to apply the solutions that meet their needs.
