Abstract

This paper examines some of the relative merits of Bus, Ring and Star topologies for Local Area Networks, and describes a new structure - the dual rooted tree. The latter produces superior performance for heavy loads and for impulse loads, while avoiding the message length limitations associated with CSMA LAN's. A 50 Mbit/s fibre-optic prototype network has been constructed and tested. A large (250 port) 50 Mbit/s fibre-optic field trial network is now being installed at the University of Toronto.
