Abstract

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.
