Abstract

The characteristics of a point-to-point demand-assignment satellite-switched multiple beam communication network are identified. The described protocol is known as Space Division Multiple Access (SDMA). It requires an on-board traffic controller, a fixed assignment scheme for capacity requests and a rigid frame structure with separate data and voice subframes. Message and circuit switching is utilized for data and voice traffic respectively. Time Division Multiple Access (TDMA) is used for the transmission of capacity requests. Synchronization is maintained by a looped-back reservation burst. A detailed analysis of the delays and blocking probabilities of data and voice traffic are presented for an arbitrary compound arrival process. A new method for the calculation of the data delay is presented and a comparison with other protocols is shown. The feasibility is demonstrated and the design of the SDMA protocol is illustrated.
