Fault-Tolerant IP and MPLS Networks
Fault-Tolerant IP and MPLS Networks
Design and deploy high availability IP and MPLS network architectures with this comprehensive guide
* Includes a detailed overview of the IP/MPLS forwarding and control plane protocols, including OSPF, IS-IS, LDP, BGP, and RSVP
* Analyze fault-tolerant IP/MPLS control plane architectures with the explanations in this book
* Develop a clear understanding of various high availability aspects of IP/MPLS networks
* Learn how to seamlessly deploy IP/MPLS control plane restart mechanisms
* Master the application of fault-tolerant control-plane architectures in designing and deploying highly reliable and available MPLS applications, such as traffic engineering, L2VPNs, and L3VPNs
* Understand the layered architecture of network-level fault recovery mechanisms, such as optical, SONET, MPLS, and interactions between different layers
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.
