ABSTRACT

The Asynchronous Transfer Mode (ATM) standards bodies such as ATM Forum and International telecommunications union-T developed sets of ATM interworking standards to allow interoperability with various network environments. This chapter reviews some of the most significant interworking standards such as Local Area Networks Emulation (LANE), classical Internet protocol over ATM, multiple protocols over ATM (MPOA), and voice and telephony over ATM. LANE is capable of providing connectivity between ATM-based end systems and end systems attached to legacy LANs. LANE is based on client/server architecture. Each emulated LAN contains many LAN emulation clients and a single LAN emulation service. The LAN emulation service is composed of a LAN emulation server, a LAN emulation configuration server, and a broadcast and unknown server. The chapter describes the components of MPOA architecture assume a client or server role. An edge device or MPOA host assumes the role of MPOA client. A Router assumes a role of a MPOA server.
