Subject: [dpdk-users]  Strange Packet Loss with number of flows.
Date: Thu, 26 Sep 2019 10:10:25 +0530	[thread overview]
Message-ID: <CAJyVW49=bNG6mzpyLfeAbbfUKqiOcsiKJv34v-2U17vhBD+kew@mail.gmail.com> (raw)

Hi,

I am having a problem with packet loss and I hope you can help me out.
When we increase the number of flows, PPM value must increase. I observed
this behavior to some point, but after that PPM value reduces. Below you
find the description of application, workload, and observations.

*Application*
I have a server-client application, a single server, and single client.
Both machines are using multiple queues to send or receive packets.


*Workload*
I'm running dpdk with fixed PPS value i.e 2 Mpps.
I'm increasing the number of flows to see the impact on PPM value.
I'm changing UDP port range to generate the number of flows.


*Observations*
Target MPPS Flows PPM
2 2 100
2 100 670
2 1000 3136
2 5000 265878
2 10000 106316
*I was expecting PPM value to rise for 10K flows, but its value reduces.*
Please share your suggestions.

Regards
Dheeraj Dang
