Examples of jmt.engine.QueueNet.NetNode

jmt.engine.QueueNet.NetNode
This class implements a generic QueueNetwork node. @author Francesco Radaelli, Stefano Omini, Marco BertoliModified by Ashanka (May 2010): Patch: Multi-Sink Perf. Index Description: Added new Performance index for the capturing the 1. global response time (ResponseTime per Sink) 2. global throughput (Throughput per Sink) each sink per class.

    //for each server ...
    for (int i = 0; i < servers.size(); i++) {
      Object thisServerKey = servers.get(i);
      // get the mapped NetNode ...
      NetNode thisNode = serverMap.get(thisServerKey);
      NodeSection thisQueue = null;
      NodeSection thisServer = null;
      // get the input section and the service section ...
