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’ ??

Most of the problems occur because of the load on the cookies. Experts from StudyDaddy.com recommend before various installations it is necessary to be released from "garbage" to avoid delays and a bug (errors)
