Demand Assigned Multiple Access Systems Using Collision Type Request Channels: Traffic Capacity Comparisons
Stephen S. Rappaport · IRE Transactions on Communications Systems · 1979
The traffic carrying capabilities of demand assigned multiple access (DAMA) systems in which requests for communication circuits are transmitted over shared collision type channels to a master controller are investigated. The circuit request protocol permits both busy and blocked responses in addition to circuit allocations. The theoretically maximum traffic capacity is determined and it is shown that even very simple systems of this type can achieve efficient bandwidth utilization in realistic situations.
