' 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))
'
