Substation Communications
Published in John D. McDonald, Electric Power Substations Engineering, 2017
ATM is a cell relay protocol that encodes data traffic into small fixed-size (53 byte with 48 bytes of data and 5 bytes of header) “cells” instead of variable-sized packets as in packet-switched networks. ATM was originally intended to provide a unified networking solution that could support both synchronous channel networking and packet-based networking along with multiple levels of service quality for packet traffic. ATM was designed to serve both circuit-switched networks and packet-switched networks by mapping both bit streams and packet streams onto a stream of small fixed-size “cells” tagged with virtual circuit identifiers. These cells would be sent on demand within a synchronous time slot in a synchronous bit stream. ATM was originally designed by the telecommunications industry and intended to be the enabling technology for broadband integrated services digital network (B-ISDN), replacing the existing switched telephone network. Because ATM came from the telecommunications industry, it has complex features to support applications ranging from global telephone networks to private local area computer networks.
Wireless networking

ATM is the switching and multiplexing ITU-T standard for broadband integrated services digital networks (BISDN). It has been advocated as the appropriate technology for wide area interconnection of heterogeneous wide area networks. It is a packet switching and multiplexing technique designed to handle voice, data, and video in a single physical channel. ATM is considered to be well suited as the transport mechanism for high-speed networks because of its support for bandwidth-intensive applications, its ability to carry different media types, and its ability to guarantee quality of service.
Performance Study on Switch and Network

To realize Broadband Integrated Services Digital Network (B-ISDN) which is intended to provide various services in telecommunications, Asynchronous Transfer Mode (ATM) is one of several data transfer technologies that are proposed and currently being developed [1]. In the ATM network, information is divided into a fixed length of data block, called cell. The ATM technology can provide high speed and high efficiency of the network because a simple data transfer protocol and wide bandwidth of optical fiber media are used in the network [2].

In recent years, Broadband Integrated Services Digital Network (B-ISDN) based on Asynchronous Transfer Mode (ATM) technology, IEEE802.11 n WLANs, circuit-switched time-division multiple access (TDMA) systems, etc. have received abound attention of the researchers mainly due to its compatibility of providing a common interface for multimedia services. The underlying mechanism of those systems is completely based on the packet switching principle in which the transmission of packets is allowed only at regularly spaced points in time generally called as a slot. Consequently, those systems can be adequately modeled and analyzed using discrete-time queues which have a notable diverse spectrum of applications in modern telecommunication/wireless systems, see, e.g. Bruneel and Kim (1993), Alfa (2010), Samanta et al. (2007b), Gupta et al. (2014), (2007), and Claeys et al. (2010a) and references therein.
