Abstract
Describes the communications software which provided the services necessary for the distributed processing used in the EHF Skynet trials in 1993. The challenge was to develop a system that was easy to integrate with the user s oftware as well as to ensure that the communications hardware and software did n ot conflict with special purpose boards in the various computers. For simplicity , stop-and-wait ARQ (Automatic Repeat Request) protocol was used for high-level message passing. Low-level communications services that do not require handshaki ng, were also provided for equipment control. The communications software package met these challenges and after extensive testing, was proven to provide the necessary communications among all the processors of the distributed system.
