perfSONAR User Q&A and Other Discussion

[Gaetano Vocca <>]

Dear all,

While performing some test campaign I receive this kind of output quite often, both when using owamp and iperf3 as tool.

Though I know there is some slowness in our network I wonder if there is any parameter that I can use with bwping or bwctl to make this frequency decrease, even at the cost of slowing down a bit the test execution speed.

 

Thank you

Gaetano
