New on RIPE Labs: The BGP Tuner: Intuitive Anycast Management
by Mirjam Kuehne 19 May '20

19 May '20

Dear colleagues, DNS operators have very few intelligent real-time tools that enable them to monitor their anycast services, for instance during a DDoS attack. In this post, Joao M. Ceron, Network Security Research Engineer at SIDN Labs, describes the challenges associated with measuring anycast services and propose a tool called the BGP Tuner. By using that open-source tool, operators can see in advance how changes in their BGP policies may impact the traffic load distribution over the anycast sites. Please find more details on RIPE Labs: https://labs.ripe.net/Members/joao_m_ceron/the-bgp-tuner-intuitive-anycast-… Kind regards, Mirjam Kühne RIPE NCC
