Abstract

Recently, new tools for Internet path characterization have been released. The tools allow finding the bandwidth, packet loss rate, average queuing delay, and latency of every hop along the path from a sender to a destination host. This has created many teaching and research opportunities in the area of computer networking. Based on these tools, many interesting assignments and projects for computer networking courses can be developed. Some of the tool developers have made their source code publicly available. As such, researchers can extend or tailor such tools to fit their needs. In this work, we provide an overview of the underlying algorithm of these tools, a usage of the tools in finding bandwidths of Internet hops and an outline for some other uses of the tools for teaching purposes.
