Abstract:

In this document, a plan is described to deploy a local area network linking together several dispersed computing facilities within The Aerospace Corporation in order to promote the sharing of these internal resources and to provide access to the unique resources of the ARPANET. This plan has grown out of two independent efforts to meet particular communication requirements 1 In support of VLSI research there is a need for the CAD VAX in D8 to communicate with the ISRO VAX in A2 and with the ARPANET 2 A Labnet, linking together several existing laboratory computers and a new medium sized computer called the Lab VAX, is required to satisfy the general resource sharing needs within the Laboratory Operations. The proposed local network meets these needs. The authors propose the use of two technologies for the implementation of this network. proNETa token passing ring using various media including fiber optic links has been selected to provide interbuilding communication. This selection was made because of its relatively long range2.5 km and because hardware is available to use fiber optic cable as a medium. Etherneta contention bus usng 50 ohm coaxial cable has been selected as the intra-building network because of its reduced cost and wide vendor support. The introduction of Ethernets should be taken into account during the procurement of new computing equipmentminicomputers, personal computers, word processing systems, etc.. New devices which are compatible with or contain interfaces to Ethernet can benefit from network services while others cannot.
