This soft copy for use by IBM employees only. Chapter 1. Introduction to ATM Networks This book is designed to help you to get the most effective use of the IBM 8285 Nways ATM Workgroup Switch as you implement an ATM network. Before going into further details about the 8285, however, it might be useful to review the basics of ATM networking, addressing, and data flows. 1.1 ATM Fundamentals Asynchronous Transfer Mode (ATM) is a high-performance network technology that is rapidly becoming the stan

This soft copy for use by IBM employees only. 1.1.2 ATM Connections ATM, being session-oriented, requires that a path through the network be determined and maintained for the duration of the session. This path is comprised of virtual channel links (switch-to-switch connections), which are linked together to form a virtual channel connection (VCC) (end-to-end connection), which are aggregated into virtual paths (VP). Just like a virtual channel (VC), a virtual path can be a virtual path link (swi

It is defined at each switch in the network and consists of an 11-byte network address and a 2-byte area identifier, which is further divided in to a 1-byte ATM Cluster Number(ACN), and a 1-byte Hub Number (HN). This results in a hierarchical network topology of: a. An ATM network comprised of b. ATM sub-networks (or clusters) comprised of c. ATM hubs In any given ATM n
