[Yeti DNS Discuss] [Yeti DNS Operators] additional dns-traffic

["Davey(宋林健)"]

Hi Dmitriy,

sorry, I found your mail lying in my junk mailbox, the same case for Shane with BII’s mailbox. 
I don’t know why. I cc discuss mailing list instead to involve more discussion on this topic.

I encourage you to do what you proposed and make necessary analysis on 1) whether traffic can spread to 
other yeti root servers (with certain NS selection algorithm) , 2) observing if there is any problem for the 
query/response, which can help us to improve our testbed

I proposed similar idea to reply the DNS traffic from production network to simulate the real 
query load, because we do not have enough resolvers right now. This will be helpful particular 
in the beginning of Yeti testbed to enhance its stability and readiness for experiments or production trial.   

In the f2f yeti meeting last week, we discuss three way to increase the traffic on yeti, 

1) resolve from Universities and research region (Like BUPT as a case) 
2) replay some real traffics  (as you proposed)
3) use some existing experimental tool like Atlas to generate traffic for special experiment;

Cheers,
Davey
