Class D service architecture in an ATM-Internet

Abstract

This paper proposes a class D service (datagram delivery) architecture in an ATM-Internet, which is the network interconnecting ATM-LANs. The datagram delivery to the destination terminal is performed by connectionless server, so called CLS, which is located in the ATM-LAN where the destination terminal belongs. Each CLS only manages the addresses for the terminals belonging to the corresponding ATM-LAN. The cells belonging to a certain datagram are transferred through a single (seam-less) ATM connection from the source terminal to the CLS in the ATM-LAN where the destination terminal belongs. The proposed class D service architecture can be applied to the ATM-LAN system based on VPI routing architecture, easily.<>
