' Macro for Analyzing the TokenBucketConformer' --------------------------------------------'' Author' ------' Rajesh Sundaram ([email protected])'' Description' -----------' This macro can be used to analyze the conformance time of packets sent out on a flow. It can be used' to determine the rate at which the app submits packets and the rate at which they get sent out.'' Instructions' ------------' * Install a checked psched' * Run pslog -m0x4000 -l10. This sets the psched logs to start collecting per packet data for the ' TokenBucketConformer' * Run pslog -f > dumpfile to clear current contents of the log.' * Begin test; send data for some time and stop the test.' * Run pslog -f > schedlogfile to collect per packet details' * Run tbc.vbs <fullpath>\schedlogfile outputfile.xls. This creates an XL spreadsheet with following columns''' 1st: Arrival Time' 2nd: Conformance Time' 3rd: Packet Size' 4th: Normalized Arrival Time' 5th: Normalized Conformance Time' 6th: Overall Rate of arrival (i.e BytesSentSoFar / CurrentTime)' 7th: Overall Conformance Rate (i.e. BytesSentSoFar/CurrentConformanceTime)' 8th: Last packet rate (LastPacketSize/(CurrentTime - LastSubmitTime))' 9th: Last conformance Rate (LastPacketSize/(CurrentConformanceTime-LastConformanceTime))''
