Sean Harnedy is a networking consultant and a software engineer. He's the author of several Prentice Hall books on network management, including 'Total SNMP' and 'Web-Based Management for the Enterprise'. He earned a B.A. from Holy Cross College, a B.S. in computer Science from Florida Atlantic University, and a M.S. in Computer Science from the University of New Haven. He has over 30 years of experience as a software engineer and technology consultant with expertise in Enterprise and Data Architecture along with Information Exchange Specifications and Data Science. Proven success across the the entire software development cycle in both structured and object-oriented environments, including extensive systems programming development and debugging especially in network management, security, telecommunications, data communications, information exchange, and protocol development. Multiprotocol Label Switching (MPLS) is a routing technique in telecommunications networks that directs data from one node to the next based on labels rather than network addresses. Whereas network addresses identify endpoints, the labels identify established paths between endpoints. MPLS can encapsulate packets of various network protocols, hence the multiprotocol component of the name. MPLS supports a range of access technologies, including T1/E1, ATM, Frame Relay, and DSL. In an MPLS network, labels are assigned to data packets. Packet-forwarding decisions are made solely on the contents of this label, without the need to examine the packet itself. This allows one to create end-to-end circuits across any type of transport medium, using any protocol. The primary benefit is to eliminate dependence on a particular OSI model data link layer (layer 2) technology, and eliminate the need for multiple layer-2 networks to satisfy different types of traffic. Multiprotocol label switching belongs to the family of packet-switched networks. MPLS operates at a layer that is generally considered to lie between traditional definitions of OSI Layer 2 (data link layer) and Layer 3 (network layer), and thus is often referred to as a layer 2.5 protocol. It was designed to provide a unified data-carrying service for both circuit-based clients and packet-switching clients which provide a datagram service model. It can be used to carry many different kinds of traffic, including IP packets, as well as native Asynchronous Transfer Mode (ATM), Frame Relay, Synchronous Optical Networking (SONET) or Ethernet. A number of different technologies were previously deployed with essentially identical goals, such as Frame Relay and ATM. Frame Relay and ATM use labels to move frames or cells through a network. The header of the Frame Relay frame and the ATM cell refers to the virtual circuit that the frame or cell resides on. The similarity between Frame Relay, ATM, and MPLS is that at each hop throughout the network, the label value in the header is changed. This is different from the forwarding of IP packets.[2] MPLS technologies have evolved with the strengths and weaknesses of ATM in mind. MPLS is designed to have lower overhead than ATM while providing connection-oriented services for variable-length frames, and has replaced much use of ATM in the market. MPLS dispenses with the cell-switching and signaling-prot.

Sinopsis

MPLS simplifies and improves IP packet exchange, giving network operators unprecedented flexibility in managing traffic and controlling network performance. This is the first complete MPLS primer for working network professionals. Leading consultant Sean Harnedy introduces every aspect of MPLS technology: concepts, standards, evolution, real-world implementation, day-to-day management, and more. Harnedy begins with an overview of MPLS and the converging technologies that led to it, including cell switching, tag switching, and Internet routing. He introduces the MPLS protocol itself, then presenting the fundamentals of MPLS signaling and label distribution. The book contains detailed coverage of MPLS operation, applications, and management; comparisons of current MPLS implementations; and a preview of future enhancements that will increase its value and extend its role. For all network administrators called upon to implement or manage MPLS and related Internet routing and switching technologies.
