' 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))
