Dear Kannan, I am working on ns-2b15 and particularly on SRM, and I have two questions: 1. For an SRM agent, are there more statistics(Loss,number of packets received) than the statistics that the "stats_" state variable returns ? If yes, how can I print them in a trace file? 2. For a QueueMonitor object , how can I print to a trace file the "pdrops_" and "parrivals" state variables? Best regards, Tasos
