The SAND team performs applied research in Anycast services aiming to provide tools and recommendations for DNS operators.
Active monitoring the visibility of the anycast sites enable to use the historical graph to predict future traffic load.
BGP Route Annouces
Modify BGP route announces enables to change each site visibility and redirect traffic from one site to another.
Assist operators to accurately distribute the traffic load across sites is fundamental to develop a defense strategy.
The problem that SAND address is that DNS operators have very few
intelligent real-time tools that enable them to monitor their anycast
services, for instance during a DDoS attack. Our goal is to develop,
prototype and evaluate tools and recommendations for anycast system
An essential part of the project is to active investigate anycast site visibility by the understanding of the dynamic relationship between Internet routing (BGP) and anycast services.
To accurately map the anycast sites visibility from the client perspective enables operators to carefully manage their systems and assisting in attacks response.
