Efficient domain name resolution using SDN architecture

Abstract

SDN is a dynamic, programmable network that follows layered architecture. The Domain Name System can be implemented in an SDN network, due to which the structural efficiency of SDN architecture can be employed on to Domain name system. For this purpose, we propose a new framework which works with four algorithms InEx (Internal/ External Check), PlyIn (for internal query), PlyOut (for external query) and FiSt (Find the Stored).
