Abstract

The recommendation X.25 ([1]) defines the interface between a network access point (data communications entity, DCE) and the network user (data terminal equipment, DTE) but the internal network service may be based on different principles. Some networks may use virtual circuit switching as an internal service whereas others could prefer datagram service or other facilities. The objective of the present paper is a comparison of four different possibilities of the internal switching networks by means of a mathematical modelling analysis. The maximum throughput of the system is used as the performance criterion. The results provide a global insight to the behavior of the system when different switching strategies are applied. They may also be used to determine the domain of other important parameters.
