Advanced teleprocessing systems

This research deals with the transmission of stream traffic through packet switched networks. Stream traffic communication is characterized by (1) a requirement of small response time and moderate throughput, the fact that (2) timing is an integral part of the information and that (3) the information is redundant and somewhat tolerable to loss. Remote voice communication provides an example of stream traffic communication. Traditional dedicated communication systems supporting stream traffic have exhibited fixed capacity and fixed delay. In such systems each user is assigned a communication link whose capacity is large enough to support that user's peak load. While timing is easily preserved by such systems, it is difficult to share communication links. This research explores systems in which the communication channels are shared among many users, thus causing delay and capacity to vary.
