Abstract
This study models the University of Kansas Packet Switch Network (PSN) as a network of queues traversed by several classes of messages. Most hardware components are represented by queues and message classes are determined both by PAD connection and by the particular host with which messages are exchanged. Users and hosts are represented by delay servers and most of the hardware components are represented as FCFS load-independent servers.
The model is evaluated using the Bard-Schweitzer approximation to a modification of the basic Mean Value Analysis algorithm for evaluating multiclass queuing networks. The MVA algorithm is modified to account for message classes with different service times at FCFS servers.
Model results are compared with actual performance data and used to examine several proposed changes to the PSN.
