Multiprotocol Label Switching
Multiprotocol Label Switching (MPLS) is a type of data-carrying technique for high-performance telecommunications networks that directs data from one network node to the next based on short path labels rather than long network addresses, avoiding complex lookups in a routing table. The labels identify virtual links (paths) between distant nodes rather than endpoints. MPLS can encapsulate packets of various network protocols, hence its name "multiprotocol". MPLS supports a range of access technologies, including T1/E1, ATM, Frame Relay, and DSL.
Mpls and VPN Architectures (Paperback)

A practical guide to understanding, designing, and deploying MPLS and MPLS-enabled VPNs

  • In-depth analysis of the Multiprotocol Label Switching (MPLS) architecture
  • Detailed discussion of the mechanisms and features that constitute the architecture
  • Learn how MPLS scales to support tens of thousands of VPNs
  • Extensive case studies guide you through the design and deployment of real-world MPLS/VPN networks
  • Configuration examples and guidelines assist in configuring MPLS on Cisco(r) devices
  • Design and implementation options help you build various VPN topologies

Multiprotocol Label Switching (MPLS) is an innovative technique for high-performance packet forwarding. There are many uses for this new technology, both within a service-provider environment and within the enterprise network, and the most widely deployed usage today is the enabling of Virtual Private Networks (VPNs). With the introduction of MPLS-enabled VPNs, network designers are able to better scale their networks than with the methods available in the past.

Network engineers and administrators need quick, effective education on this technology to efficiently deploy MPLS-enabled VPNs within their networks. With that goal in mind, MPLS and VPN Architectures provides an in-depth discussion particular to Cisco's MPLS architecture. This book 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 its mechanisms are explained with configuration examples, suggested design and deployment guidelines, and extensive case studies.

MPLS and VPN Architectures is your practical guide to understanding, designing, and deploying MPLS and MPLS-based VPNs.
