perfSONAR User Q&A and Other Discussion

[Jason Zurawski <>]

Hakan;

pSB is compliant with the schemas in the NMWG svn repository 
(http://anonsvn.internet2.edu/svn/nmwg/trunk/nmwg/schema/).  BWCTL data 
follows the format of 'iperf.rnc' and OWAMP follows the format of 
'owdsummary.rnc'.

I have added schema directories to the pSB package that show the 
specific formats of the messages you have requested, you can access them 
here:
