A First Look at Anycast CDN Traffic

Understand

Anycast routing is an IP solution that allows packets to be routed to the topologically nearest server.

• Over the last years it has been commonly adopted to manage some services running on top of UDP, e.g., public DNS resolvers, multicast rendez-vous points, etc.
• However, recently the Internet have witnessed the growth of new Anycast-enabled Content Delivery Networks (A-CDNs) such as CloudFlare and EdgeCast, which provide their web services (i.e., TCP traffic) entirely through anycast.
• To the best of our knowledge, little is known in the literature about the nature and the dynamic of such traffic.
