Basic Teletrafic Model for a Party Line

The paper discusses a basic teletraffic model for any kind of collective telecommunication line used by subscribers (or stations) located along the line. Bus topology with communications of the stations in pairs and blocking is used as the basic teletraffic model of such a line. The Markov model describing teletraffic processes in a party line provides an explicit solution for the state probabilities of the line and, hence, for all significant traffic characteristics. Ways of extending the model for the bus with a gateway and for the ring topology, as well as for delay systems, are also discussed.
