Extra resources for ATM & MPLS Theory & Application: Foundations of Multi-Service Networking

Example text

The text separates the description of the user and control plane protocol stacks for Frame Relay as an introduction to a similar separation of function employed in ATM and MPLS. Chapter 8 describes the key connectionless packet switching protocols defined for use in communication networks. The focus is on the Internet Protocol (IP), with some historical information also provided for Switched Multimegabit Data Service (SMDS). This chapter traces the background of each protocol, details the packet formats, and illustrates key operational aspects through examples.

Evolving corporate infrastructures require communications networking flexibility to respond to ever-changing business needs. Reorganizations, mergers, and layoffs frequently place information workers in different physical locations, accessing different network resources. These factors drive network designers to distribute the storage and processing of data to servers supporting groups of clients. The result is that an increasing amount of computing occurs via distributed processing using the client/server paradigm, which is precisely the model of the Internet.

This chapter covers the manner in which MPLS labels are encoded over various physical and logical networks. It particular, it describes how MPLS can run over SONET, ATM, Frame Relay, or Ethernet. Chapter 12 describes the ATM Adaptation Layer (AAL), which provides support for all higher-layer services, such as signaling, circuit emulation, Frame Relay, and IP. Since MPLS standards are not yet complete in this area, this chapter summarizes the current state and direction of MPLS infrastructure being defined with the aim of supporting multiple services.
