Communication network analysis with COMNET 11.5

ABSTRACT

COMNET II.5 is a general SIMSCRIPT II.5-based model for the performance analysis of circuit, message, or packet-switching networks. A variety of routing algorithms are built-in. After creating a network description with a convenient menu-driven editor, simulation follows immediately. There are no programming delays. Network operation is animated during the simulation. Reports show blocking probabilities, call queueing and packet delays, network throughput, link group utilization, and link group queue statistics. Some of the major enhancements that have been added to COMNET II.5 during the past year include capabilities for modeling multidestination messages, empirical probability distributions, flood routing, and access facilities. An access facility can be a point-to-point or multipoint line or a local area network.
