Creating a Scalable Architecture for Internet Measurement Download


Historically, the Internet has been woefully under-measured and under-instrumented. The problem is only getting worse with the network's ever-increasing size. We describe an architecture for facilitating a ``measurement infrastructure'' for the Internet, in which a collection of measurement ``probes'' cooperatively measure the properties of Internet paths and clouds by exchanging test traffic among themselves. The key emphasis of the architecture, which forms the underpinnings of the National Internet Measurement Infrastructure (NIMI) project--is on tackling problems related to scale. Consequently, the architecture emphasizes decentralized control of measurements; strong authentication and security; mechanisms for both maintaining tight administrative control over who can perform what measurements using which probes; delegation of some forms of measurement as a site's measurement policy permits; and simple configuration and maintenance of probes. While the architecture is general in the sense of not being tied to any particular measurement tools, it also currently supports ``TReno'' [MM96], ``poip,'' and ``traceroute'' [Ja89] measurements.
