Automated internetworking using HF radio links

The automation, usability, throughput, and reliability of HF radio links has now been raised to the point where an HF link can act as a network component, allowing normal network services in ways and configurations not previously economically or operationally possible. This paper describes the capabilities and expected performance of such a system, and describes a vision of the future of HF radio in networking. A system currently under development will connect to an Ethernet LAN (using TCP/IP) and act as a gateway to other LANs. These systems accept requests from users through TCP/IP and forward those requests through an ALE-managed HF radio network. They then deliver the information to the destination LAN, where it is sent to the intended user or machine. The first implementation will include file transfer (text and binary) and electronic mail service, using the tools and interfaces that the users are currently accustomed to.<>
