I would like to ask for clarification of the operation of BWCTL and OWAMP on 
the same host and same interface:

When running on the same host and same interface, my understanding is that a 
BWCTL throughput test will disrupt OWAMP results when the throughput test 
runs.  I.e. there is no scheduling process that pauses OWAMP while the 
throughput test runs.  Hence, the recommendation that OWAMP and BWCTL 
throughput testing be run on different interfaces.  Is that correct?

I think I read that there is a plan to add owping to BWCTL test options to 
enable third part testing.  Is that in the plans?

Thank you!
Kathy
