The Impact of the X.25 on the Efficiency of the Communications Subnetwork
A. Butrimenko, U. Sichra · IIASA PURE (International Institute of Applied Systems Analysis) · 1980
The acceptance of the X.25 international standards requires a virtual call procedure, which imposes some restriction on the usage of communication resources, namely a fixed route for the whole duration of the session. In an example of network simulation, datagram and virtual call methods are compared, producing the result that the datagram gives a better performance with regard to delivery time. The difference between these two methods is greater when the load, the number of packets per message, and the size of the network is increased.
