Abstract

The recent evolution on the network tomography have successfully provided principles and methodologies of inferring network-internal (local) characteristics from only end-to-end measurements, which should be followed by deployment in practical use. In this paper, we propose two types of user-oriented tools for inferring one-way packet losses on paths from/to an user-host (a client) to/from a specified target host (a server or router) without any measurement on the target, which utilize a method based on the network tomography. One is a stand-alone tool running on the client, and the other is a client-server style tool running on both the client and proxy measurement server(s) distributed in the Internet. Both of them can infer one-way packet loss rates not only on a path between the client and an application server, but on a path segment (a portion of the path) between the client and any router residing in the path, and thus can find the congested area along the path. We have developed prototypes of the tools and have evaluated them in experiments in the Internet environment, which showed that the tools could infer one-way packet loss rates within 1% errors in various network conditions.
