perfSONAR User Q&A and Other Discussion

[Aaron Brown <>]

Hey Brian,

Yeah, the normal configuration for the Toolkit is to only do outbound ping 
tests since we can’t be sure that bwctl is running on the far side to do 
inbound ping tests. I’m not sure about the graphing though. Bidirectional 
tests can be configured with some config file modification.

Cheers,
Aaron
