Review of Domain Name System
In this paper, the authors focuses on performance optimization of network by using co-located domain name systems. The paper involves understanding of the flow of traffic from source to the destination, load balancing among servers evenly in order to provide sufficient quality of service to end-users, and the need of co-located DNS is because it picks data from the nearby available servers. Performance of co-located DNS will be measured and analyzed so that better solution can be proposed and various tools for analyzing and monitoring are to be used for measurement and analysis purpose. They can measure and analyze the response time for the input, latency, bandwidth, flow of traffic, delays etc.
