Measuring One-way Loss with GRE Encapsulated Multicast Probing

This talk describes some techniques for estimating one-way loss from a measurement host to network routers, which exploit commonly implemented features on commercial routers and do not require any new router capabilities. The work addresses the problem of scalably performing one-way loss measurements across specific network paths. This is joint work with Lee Breslau, Yu Gu and Shubho Sen.
