Experience with Autonet

Thomas L. Rodeheffer

Abstract

Autonet is a self-configuring, switch-based local-area network with automatic routing of individual Ethernet-style packets. The twelve ports on each switch may be connected to host controllers or other switch ports in arbitrary configurations. A distributed control program running in the switches monitors the state of the network, determines deadlock-free routes for all sources and destinations, and sets up hardware forwarding tables for each switch. A link is a single wire of cable-television coax up to 100 m long, passing data at 100 Mbit/s simultaneously in each direction.

Functionally, Autonet looks like Ethernet, but it is faster, easier to manage, and more available. Autonet has excellent performance and can grow easily and economically by adding redundant links and switches to provide increased throughput. Automatic reconfiguration and failover enable the network to operate in any configuration, to defined itself against intermittent components, and to be repaired while still in operation.
