In the wake of increased traffic, today's service providers and enterprises must assure high availability across a variety of networked services and applications. Multiprotocol Label Switching (MPLS) is the enabling technology for the widespread deployment of IP networks in core and Metro Ethernet applications. Many service providers need to move their legacy Layer 2 and Layer 3 services onto converged MPLS and IP-enabled networks, but high availability is a prerequisite for offering profitable carrier-class services. Although most carrier-class routers do provide an adequate level of hardware redundancy, control-plane software is still vulnerable to and, in many cases, the cause of router failures. Fault-Tolerant IP and MPLS Networks provides you with an in-depth analysis of the mechanisms that improve the reliability and availability of IP and MPLS control plane components. The IP/MPLS control-plane architecture and all its restart mechanisms are explained with examples and deployment considerations.

Multiprotocol Label Switching (MPLS) provides the mechanisms to perform label switching, which is an innovative technique for high-performance packet forwarding. This book provides an in-depth study of MPLS technology, including MPLS theory and configuration, network design issues, and case studies. The MPLS/VPN architecture and all of its mechanisms are explained with configuration examples and suggested deployment guidelines. MPLS and VPNs provides the first in-depth discussion particular to Ciscos MPLS architecture. Multiprotocol Label Switching and Virtual Private Networks covers MPLS theory and configuration, network design issues, and case studies as well as one major MPLS application: MPLS-based VPNs. The MPLS/VPN architecture and all of its mechanisms are explained with configuration examples, suggested design and deployment guidelines, and extensive case studies.
