I was reading a research paper entitled "Steps to Defend Against DoS Attacks" when I came across this point:
"A reflection attack on a server would require server-client-server communication, and most clients are not going to respond to a new connection request from a server and hence reflection attacks on server will be prevented"
It was written under the heading of Application of IPv6 addressing aiming to prevent DoS attacks.
My question is that how server-client-server communication is needed for reflection attack on a server?
I Googled for it but couldn't get to answer.
