Data transmission network computer-to-computer study

Abstract

This study addresses the problems of designing a low undetected error rate (e. g., 10−8) communication system for the transmission of large quantities of computer data between two remote locations. The study effort includes a characterization of the interconnect channels, and an analysis, evaluation and recommendations for coding techniques. The channel characterization effort is directed toward producing a model of the interconnect links. The model is shown to be representative of real interconnect links based on a comparison with measured bit error data. The error correcting coding effort is directed toward the development and evaluation of forward error correcting (FEC) coding techniques based on generalized burst trapping codes. In addition, consideration is given to automatic repeat request (ARQ) error control. Several basic approaches to providing error control for the computer-to-computer data transmission channel are considered.
