Modeling of a multi-link transport connection by a network of queuing systems

A model of a multi-link homogeneous transport connection with limited buffer storage in transit nodes as a network of queuing systems with discrete time is proposed. An estimate of the lower bound of the capacity of the transport connection throughput is obtained. The effect of a set of successive absolutely reliable data links located between two nondeterministic retransmission sections of a given quality on the operational characteristics of a transport connection is found
