The open-ring/active-bus network structure: access techniques and their heavy-traffic performance

The open-ring/active-bus network structure for packet-switched, multiple-access communication over high-speed fiber-optic networks is studied. The structure is shown to suffer from fewer synchronization constraints than a closed ring structure and to provide a capacity greater than unity because it allows reuse of channel bandwidth. Various access mechanisms on this structure are discussed, and their channel capacities are analyzed.<
