Hi,
Please take a look at some more detailed test - with burst step 100 (instead
of 1000 packets)

Hi,

Sorry, I didn t see from the report that there are two ingress and one
egress report, I m not used to looking at reports like this. Topology
helps.

So does this show that if these are 100G links, and you have 10G on two ingress ports, there s drops rather than a clean 20G aggregate on the egress? I d not expect any drops in this scenario, but that may be naive :)

Hi,
You can se that in 6th step we noticed a number of dropped packets. This mean burst size was 1+5x1000 for every ingress interface. So we can say that the buffer size is ~8000 packets (IMIX size distribution)
This is also independent from load (you can see similar effect for different
load values)

Hi,

Thanks for the initial test results. I m not sure how to interpret them.
I can see there are losses at certain points, but it s unclear to me what
the tests are testing :)

Hi,
I just finished first approach. Please take a look at attchached report. It was made with Burst size step 1000. Unfortunately this is not included in tables. First value for each load size is burst 1, next is 1000 and so on.

Hello

Le 04/03/2022 10:35, Tim Chown a crit :

The Internet2 people are about to play with 400G Edgecore!

Something to consider? Would Tomek be able to test it with RARE/FreeRtr? :)

FYI, Tomasz is right now restarted the 100G test of RARE/freeRtr switch in
Pozna . Csaba kindly helped him yesterday to solve an issue related to a
laser

Stordis says a 400G switch is coming. Will have 400G edgecore very soon.
