Design of a multiprocessor based satellite packet communication processor for integrated services networks
Abstract
The design, hardware, software and protocols for the experimental satellite packet communications system (SPAC) are described. SPAC is intended to offer access from distributed terminals, high speed data transmission and voice, teleconferencing and local area network interface advantages. A SPAC processor capable of 2.4 kbps-1.5 Mbps user transmission rates has been devised to support the various types of traffic in a TDMA mode. Data buses route and handle simultaneous transmission/reception to maintain high bit rates. Protocols either discard frames with errors or allow transmissions to several locations at once. Priorities can be established for transmission sequences. A data encryption algorithm provides security for users. The first test of the system, routed through the Intelsat V satellite, was scheduled for autumn of 1983.
