PEERING: An AS for Us
报告人 : Italo Cunha (Federal University of Minas Gerais, Brazil)PEERING is a testbed that provides safe and easy access for researchers to the Internet's BGP routing system, enabling and inspiring transformational research. Traditionally, the barriers to conduct Internet routing experiments hindered progress. Most research on interdomain routing is either based on passive observation of existing routes, which cannot capture how the Internet will respond to changes in protocols or policies, or based on simulations, whose fidelity is restricted by known limitations in our understanding of Internet topology and policy. To move beyond these limited experimental approaches, the PEERING testbed connects (via BGP) with real networks at universities and Internet exchange points around the world. Instead of being observers of the Internet ecosystem, researchers become participants, running experiments that announce/select routes and send/receive traffic directly with these networks. In this talk, we present an introduction to the testbed and a sample of the research it has enabled.
