Packet Switching in a Multi-Access Broadcast Channel with Application to Satellite Communication in a Computer Network,
Abstract
The report considers a packet switching technique applicable to packet communication using a satellite or ground radio channel. The objective of this research is to develop analytic models for the evaluation and optimization of the system performance in terms of stability, throughput and delay. Advantages of packet switched satellite and ground radio systems over conventional wire communications for large computer-communication networks are discussed. The emphasis of this research is on a high-speed channel shared by a large population of 'small' users. The channel behavior is typical of 'contention' systems in which the throughput vanishes to zero as the load on the system increases. This phenomenon is called channel saturation. The channel may go into saturation as a result of (a) time fluctuations, and (b) stochastic fluctuations in the channel input. The channel response to time varying inputs is first studied using a deterministic approximation analysis. The effect of (b) is then studied through probabilistic models. (Modified author abstract)
