perfSONAR User Q&A and Other Discussion

[Tao Zhang <>]

Hi perfSONAR community,

 

As we are planning to redeploy our perfSONAR nodes, we have done thorough tests among our perfSONAR boxes. All the nodes are running perfSONAR Toolkit v4.0.0.1.

Here are the throughput test results:

 

Source	Destination	Results
Centos6.9	Centos6.9	Clean 10G Path (not have a single retransmission within years)
Centos7.3	Centos7.3	Packet Retransmission (can reach 10G, but have packet retransmission once in a while)
Centos6.9	Centos7.3	Packet Retransmission (can reach 10G, but have packet retransmission once in a while)

 

It looks like the perfSONAR 4.0 doesn’t work very well with Centos 7.  I checked the perfSONAR Lookup Service Directory and found that most nodes are still running on Centos 6.9. I suspect that it may be the reason the problem is not fully exposed.

 

Anyone has similar problems?

 

Thanks
