Model updates since last meeting

• Summary: – QoS and Parameterization

• Packet object– Carry priority in packet (0=hi 7=low)

– Support linked lists of packets

• Packet Queue– New object

– Enqueue, Dequeue, Fullness and Max depth

• Switch object– Significant changes: Support QoS

– No more Lindley’s recurrence

– Each port has X egress queues with strict priority

– New method to set the number of queues per port

– Improved debuggingAnue Systems Inc 2

Model updates since last meeting (cont.)

• PacketGeneratorPCAP object– Repeating/looping a file N times or forever– Assigning a priority to all packets from a pcap file– Change time scaling to bandwidth scaling– Allow “NUL” pcap filename to disable generator

• Packet MonitorPCAP object:– Change to three column output format <time, delay, drop>– Allows nonCBR packet support

• Three plotting utilities (using GNUplot)– Out2png.pl – convert three column output to PNG– Out2hist - convert three column output to CSV histogram– Histo2png.pl – CSV histogram to PNG

Model updates since last meeting (cont.)

• Parameterized script for simulator control– File name of parameter script is specified on the command line– Format is a TCL script (makes it flexible and extensible)– Parameter script knows its own name and directory (makes

it easy to organize directories for output files)– An example parameter script is provided– Many parameters have default values

• Started creating one severity parameter file– “tc/sev1/sev1.param”

• Minor changes– Removed instrumentation generators and monitors– Updated copyright notices
