I've successfully installed/compiled brahmaputra.1.0.tar.gz in a Fedora 22 environment. I have two back-to-back systems with 2 x Intel 82599ES 10-Gigabit SFI/SFP+ on both systems. One system will run pktgen and the other will run vsperf. My questions relates to how do I extract answers from pktgen output for questions from vsperf? i.e. What was the result for 'frames tx'? Where in pktgen output do I get this information?, i.e.

Basically how can I answer the following questions from VSPERF from data output provided by pktgen?

VPSERF will ask you for: Result for ‘frames tx’ Result for ‘frames rx’ Result for ‘min latency’ Result for ‘max latency’ Result for ‘avg latency’

  • I don't see any latency data from pktgen
  • Is the ‘frames tx’ and 'frames rx' data gotten from the following pktgen output?

Port 0 Total Rx Pkts : 1522072448 < 'frames rx' ??
Tx Pkts : 2153904388 < ‘frames tx’ ??
