“…In the following years, we expanded our community network around the testbed, deploying anycast sites around the world. Several researches were carried out along the years using the TANGLED network: anycast catchment studies [26] and the tool called VERFPLOETER [27]; and several anti-DDoS studies from [14], [15] were carried out using our testbed. Moreover, the TANGLED testbed is actively being used in the projects SAND [28] and PaaDDoS [29].…”

Anycast routing is an area of studies that has been attracting interest of several researchers in recent years. Most anycast studies conducted in the past relied on coarse measurement data, mainly due to the lack of infrastructure where it is possible to test and collect data at same time. In this paper we present Tangled, an anycast test environment where researchers can run experiments and better understand the impacts of their proposals on a global infrastructure connected to the Internet.

“…Some researchers suggest using BGP attribute manipulation for traffic engineering purposes [72], while others recommend improving anycast through topology modifications [95,187]. Additionally, it is noted that for anycast routing to effectively balance the load during an attack, careful planning, implementation, and measurements are essential [27,96].…”

ISPs, DNS-operators en operators van nationale onderzoeksnetwerken over de toenemende centralisatie van DNS-resolvers. Deze discussies leidden ons ertoe om een gefedereerd model voor anycast-netwerken tussen ISPs en DNS-operators voor te stellen. Daarbij hebben we de belangrijkste eisen aan zo'n gefedereerd model geïdentificeerd en een onderzoeksagenda opgesteld die gericht is op het opbouwen van een anycast-federatie voor DNS-resolvers.Door deze bijdragen bevorderen we de wereldwijde adoptie van anycast. Door de instapkosten verbonden aan infrastructuur te verlagen en het beheer te vereenvoudigen, kunnen er nieuwe aanbieders van anycast-diensten ontstaan. Op termijn zou dit mogelijk de huidige centralisatietrend van DNS kunnen keren.

IP anycast has become a vital technology for DNS and CDN operators alike. Yet, while big operators have their tools to monitor and configure anycast routing, most of anycast networks are still configured manually. In this paper, we introduce a new approach to anycast management. Our solution is based on active measurements combined with traffic engineering. We propose the concept of a "BGP Cookbook" that allows operators to forecast the effects of routing policy changes over their services. We also introduce a web-based interface, called "BGP Anycast Tuner", that allows operators to gain insight into their service's performance and provides easy management through automation. We evaluate our approach by implementing a prototype running in a testbed composed of 12 anycast sites covering 5 continents. We demonstrate our tool in two different use cases: discovering and fixing a sub-optimal anycast routing issue, and shifting traffic between continents, which is useful during service disruptions.
