perfSONAR User Q&A and Other Discussion

Question: is it normal for "ping" tests to send in only one direction, 
i.e. outbound from the perfsonar box?

This seems reasonable, but it's not clear in the documentation. What's 
particularly confusing is that the sample graph at

http://docs.perfsonar.net/using_graphs.html

has legends for both "ping" and "reverse ping", suggesting that ping is 
checked in both directions (using bwping?) - although the same graph 
doesn't actually show any ping data.

What I'm actually seeing is pings only sent in one direction (from 
perfsonar to remote host and back again).  And these tests are shown in 
the legend as "reverse ping" - there is no "ping" legend.

Is this correct?

Thanks,

Brian Candler.
