Bill Woodcock (Packet Clearing House)
Bill will discuss Packet Clearing House's experiences in their last ten years of collecting data about Internet topology, focusing specifically on the practical aspects of constructing a supportable, global-scale data collection platform. PCH is a research institute and development aid agency, which has worked to support both the academic and operational communities' needs for robust and instrumented Internet infrastructure. PCH's data-collection and experiment-hosting platforms are present at more than thirty Internet exchanges around the world, including both large regional exchanges in cities like Palo Alto, Tokyo, London, and Johannesburg, and smaller local exchanges in Kathmandu, Dar es Salaam, Dhaka, and Wellington. These are collectively managed instances of an identical installation package, and participate in the global BGP routing system using unicast IPv4, IPv6, anycast, and multicast routing.
