Data Network Design: Packet-Switching Frame Relay 802.6/DQDB SMDS, ATM B-ISDN, SONET

This reference guide is designed to help engineers and managers understand emerging technologies and design advanced data and computer communications networks. It details the technologies currently available, including X.25 Packet Switching, Frame Relay, Cell Switching (IEEE 802.6 SMDS), FDDI, SONET, and ATM - and it provides guidelines for choosing the correct technology. The guide also takes readers step by step through the decision processes involved in completing an end-to-end network design. By following the chronological order of a true network design in this way, readers will see how to begin and complete an entire network design using this single, professional reference source. The guide provides the source of each standard, offers information on where to find additional details within the standards and highlights the strengths and weaknesses of each technology in network design. It also bridges the technology gap between data transport and LAN technologies, includes case studies using vendor technologies now available and covers high-level organization details, as well as low-level technical details
