A microprocessor-controlled packet transmission system

Abstract

This paper describes a generally applicable microprocessor-controlled packed transmission system particularly suitable for small-scale point-to-point links. Fixed-length packets of any size may be exchanged on a full-duplex basis within the proposed system, where a virtually error-free transfer of information is achieved by means of a highly reliable protocol. The inherent sequentiality of the transferred packets is maintained by the system, so that data reassembly is not required. The effectiveness of the link, which is currently exploited in a local area, packet-switched network for real-time instrumentation and control, has been successfully verified.
