A key to the stable operation of this service is a solid understanding of the traffic it responds to and how it evolves over time. With the success and growth of the Internet, traffic to the DNS root servers has increased and K-root produces terabytes of raw packet capture (PCAP) files every month. We were looking for a scalable and fast approach to analyse this data. In this article I will explain how we use Apache Hadoop and why we open-sourced our PCAP implementation for it.… Read more
