A manual for practicing and student telecommunications engineers. First sets out the foundations and standards of networking, then examines the operation of different types of communication equipment and communications carrier line facilities, methods to determine the minimum level of performance required to avoid internetwork degradation, and several mathematical models that can be adapted to specific environments to project different types of performance prior to ordering hardware or communications facilities. Updated from the 1993 edition to include innovations such as Fast Ethernet, Windows NT, data-link switching, and virtual LANs and networking. No bibliography.
