about RTT.

[HeePok Lee]

Hi! all
I heard about RTT(Round Trip Time) on DNS.
But I don't know what it is exactly.
Could you explain what it is?
And if we have two name servers in America(america.nameserver.com) and in
Asia(asia.nameserver.com)
"Cache name server in Asia can always resolve to asia.nameserver.com about
www.nameserver.com and
cache name server in America can always resolve to america.nameserver.com
about www.nameserver.com"
I heard that it is right cause RTT.
Is it right?

Thank you!!!!!
