perfSONAR User Q&A and Other Discussion

[Verena Venus <>]

Hi Vicky,

I am not aware of a BWCTL MA interface in the perfsonarUI software, but there 
is a BWCTL MP interface. I think maybe you have tried this one to contact 
your MA. However, this plugin was not written to communicate with MAs. To 
summarize: Unfortunately, I do not know how you can test your BWCTL MA, but I 
fear it might not be possible with perfsonarUI.

The error message indicates that you did not provide a hostname or IP 
address, 
which could be used as endpoint for BWCTL measurements. What was the content 
of the "Source Address" and "Destination Address" fields?

Regards,
Verena
