As part of the effort to build a network lab at the University of Arkansas, several hypertext tutorials are under development to facilitate the introduction of networking concepts to students. The topics of these tutorials include network protocol analyzers, installing commercial networks, and videoconferencing. The prototype tutorial for the network protocol analyzer is written in Ntergaid's HyperWriter and includes a small protocol analyzer program called PROTAN for the TCP/IP Suite . The network protocol analyzer tutorial takes the student through the functions of a typical protocol analyzer, such as network monitoring, specific condition testing, filtering based on specific criteria, and data collection and analysis. The tutorial discusses PROTAN and its code, contains a glossary of networking terms, and presents a short tutorial on hypertext. PROTAN is also compared to the functions available in commercial protocol analyzers.
