Approaching B-ISDN: An Overview of ATM and DQDB

Asynchronous Transfer Mode (ATM) is the internationally agreed upon technique for transmission, multiplexing, and switching in a broadband network. It is designed to support the integration of high quality voice, video, and high speed data traffic. Although much work is underway in the definition, design, and development of ATM, many important components of the ATM network have not been solved. ATM is a transfer mode suitable for implementing broadband networks (WAN, MAN, and LAN) but not a network architecture in and of itself. Although, the origin of DQDB MAN is unrelated to ATM, the work by IEEE 802.6 that lead to the standardization of the DQDB will be the introductory step to ATM and B-ISDN. The relationship between ATM and DQDB is explained and a detailed discussion on the open and challenging problems that remain to be solved for ATM is presented.
