Demonstration Experiments for Continuous Internet Services in case of a Large-scale Disaster
Overview of Activity
DNS is the name resolution method for the Internet. Historically, various technology innovations have been applied to DNS for the purpose of enhancing its reliability and fault-tolerance capabilities, one of which is the IP Anycast technology that enables geographical server distribution.
JPRS has been actively conducting research and development for the purpose of enhancing the reliability and fault-tolerance capabilities of its DNS, applying the IP Anycast technology. Evidently, JPRS has improved the reliability of ".jp" as a whole of the integrated DNS, by introducing the IP Anycast technology and distributing the DNS servers in multiple geographical locations.
In this research project, JPRS assumes the occurrences of large-scale disaster situations, which may cause a state of emergency and a specific regional network to be isolated from the Internet, losing connections to the root servers and/or Top-Level Domain (TLD) DNS servers. And under those circumstances, we shall not only lose the DNS resolution capability, but we shall also lose the availability of the Internet-based services within that specific regional network.
JPRS argues that providing the DNS resolution on a continuous basis will not only contribute to the enhancement of the DNS reliability, but it will also provide continuous availability of Internet-based services, even in a state of emergency.
In this research, JPRS has investigated and verified the continual operability of DNS resolution for ".jprs" domain name, under the condition that the ".jprs" DNS servers have been located in an ISP network, where JPRS network has been disconnected/separated from the Internet.
