TLDR
Demand assignment of satellite power on a call-call-by-call basis results in increased system capacity because the probability that a call is blocked is not readily available, and standard formulas commonly used for the Poisson and Erlang B traffic model cannot be directly applied.Abstract:
Demand assignment of satellite power on a call-call-by-call basis results in increased system capacity The probability that a call is blocked is not readily available, and standard formulas commonly used for the Poisson and Erlang B traffic model cannot be directly applied Expressions for blocking probabilities are derived here for fully variable, variable-source, and variable-destination demand assignments A numerical example is given for their application in a network of terminals of varying sizes and known point-to-point trafficread more

A multiserver queue with narrow- and wide-band customers and wide-band restricted access
Y. De Serres,L.G. Mason +1 more
TL;DR: A multiserver queueing system with two classes of customers is considered: a type-1 (narrowband, NB) customer requires a single server, while each type-2 (wideband, WB) customer requests n of the m servers (n is not random).

Satellite capacity allocation
J.M. Aein,O.S. Kosovych +1 more
TL;DR: It is shown that the capacity required to provide a specified grade of service is strongly dependent upon the particular allocation strategy chosen, and an allocation strategy can be selected which requires less capacity and hence provides more efficient utilization of the satellite capacity for a specifiedgrade of service.

Multiple-access techniques for commercial satellites
TL;DR: The ability of various types of multiple-access systems to meet the requirements of a very wide range of network requirements is discussed in this article, where the authors present a promising multiple access technique of the future which includes time division switching on board the satellite.
