Abstract

RFC #302, Exercising the ARPANET, described a group organized at UCSB to investigate the network resources. The stated goals were to develop problem solving capability and, in the process, produce helpful criticism for the nodes investigated. This report summarizes the group's experiences and finding and suggests network refinements to improve user satisfaction.

EVALUATION OF ARPANET SERVICES

January through March, 1972

ABSTRACT

RFC #302, Exercising the ARPANET, described a group organized at UCSB to investigate the network resources. The stated goals were to develop problem solving capability and, in the process, produce helpful criticism for the nodes investigated. This report summarizes the group's experiences and finding and suggests network refinements to improve user satisfaction.

The group's encounter with ARPANET included many unexpected problems and difficulties. Most worthy of mention are software heterogeneity and inadequate documentation.

From this first hand experience the group has formulated criteria for ease in use of network resources. The report presents these criteria as well as suggestions for improved documentation, better utilization of current resources, and a plea for regular usage of inter-personal communications facilities. Individual sites have been graded on reliability, response, and friendliness. Comments regarding specific sites have been included to help in adapting to the needs of uninitiated users.

Despite problems encountered in the initial nine week exposure, enough was learned of ARPANET resources to enable the group to write useful software. Programs to effect automatic login, file transfer, and interprocess communication have been written and put to use.

BACKGROUND

Approach

The test group was organized from a group of Electrical Engineering graduate students in Computer Science. Within the group was represented a substantial degree of experience with high level languages and time sharing systems (such as the Dartmouth BASIC and UCSB mathematical graphics systems). However, no one had experience in exercising ARPANET, and few knew what resources the ARPANET represented. After two weeks of presentation from Jim White and Roland Bryan, the group was turned loose for open experim...
