Introduction to Networking Technologies

There are many different computing and networking technologies -- some
available today, some just now emerging, some well-proven, some quite
experimental. Understanding the computing dilemma more completely
involves recognizing technologies; especially since a single
technology by itself seldom suffices, and instead, multiple
technologies are usually necessary.

This document describes a sampling of technologies of various types,
by using a tutorial approach. It compares the technologies available
in the three major technology areas: application support, transport
networks, and subnetworking. In addition, the applicability of these
technologies within a particular situation is illustrated using a set
of typical customer situations.

This document can be used by consultants and system designers to
better understand, from a business and technical perspective, the
options available to solve customers' networking problems.
