Exact Queuing Model of Heterogeneous Local Communication Network

The object of the research in the article is a heterogeneous local communication network. In such network, a complex access protocol is used to access the channel and transmit messages. This protocol implements the principles of access control which are used in the controlled and token access protocols, synchronous random access. Proposes exact model of queues in the considered communication network. This model is developed in discrete time and takes into account the states of the buffer of considered communication station and allows to determine capacity of its buffer.
