Internetworking: Automated Local and Global Network Monitoring

摘要

Commercial applications for network monitoring are expensive and therefore notwidely available to the majority of network users. Public domain network monitoring software is generally effective in the hands of an expert but difficult to use by the common user because of its command line driven interface. It is a basic tenet of this thesis that network performance and security can be improved if all network users had easy-to-use network monitoring tools available and were encouraged to use them frequently. In this thesis, ping, traceroute, and nslookup were integrated with the familiar user-friendly interface provided by the World Wide Web (WWW) and HyperText Markup Language (HTML) in both automated and interactive versions. These easy to use monitoring tools were evaluated in several working environments at the Naval Postgraduate School and the Monterey Bay Area Network. ping, trace route and nslookup can now be performed in one-sixth of the time previously required for an expert user. Current network status is now readily available and can be validated at any time through the use of the applications developed in this thesis.
