An Adaptive, Packet-Switched HF Data Terminal -Functional Overview and Initial Performance

Abstract

This report describes the first-prototype version of an automatic, adaptive HF data terminal developed from 1983-1986. The terminal's main forms of adaptivity include a real-time channel evaluation and channel selection mechanism, an adaptive link protocol for channel optimization, and a fully distributed and adaptive routing algorithm for the selection of routes in an HF network. The terminal design is characterized by a suite of robust, low- overhead, adaptive protocols that work in low-bandwidth, error-prone and time- variant environments. The terminal's performance is illustrated with results from tests over short and long HF links carried out in Fall 84 and Winter 85-86.
