An experimental study for the performance assessment of the DNS server architecture on IPv6 network

Abstract

In this paper, an experimental investigation is conducted to study the performance of the educational research domain name system (ER-DNS) hierarchical server network which works on internet protocol version 6 (IPv6) only, instead of the publicly available dual stack DNS root servers on the internet. There is a high probability of making the entire internet system unstable if any changes are made. Thus, we have created the experimental testbed, which functions similar to the existing live internet systems. It thus gives more flexibility to experiment and make technical and operational changes, without risking the stability and reliability of the internet system. In this paper, we have setup the entire DNS hierarchy starting from the root to the recursive servers with the top level domain (TLD) and domain authoritative name servers has been setup. This setup enables the queries to flow from the end user recursive servers to the domain authoritative server via the root as well as the TLD servers and provide the result to the end user. Query response in each of these servers were recorded to derive the response time, failure and successes to help in assessing the efficiency, behavior, functionality, stability and reliability of the ER-DNS architecture in IPv6 networks.
