Abstract:
Due to the Internet structure and routing the only way to map its topology is by having measurement presence in almost every corner of the Internet. Managing thousands of measurement boxes is impractical, thus, we suggest instead a light software measurement agent to be downloaded by volunteers around the world. The DIMES agent can be executed on every PC (and in the future even smaller devices, like PDAs) and enable us to map the Internet and track its evolution in time in several levels of granularity from the fine router level to the coarse Autonomous System (AS) level. We can already report, after only four months of deployment, 30% new inter-AS connections that were revealed by DIMES. Our measurements can be extended to include not only connectivity, delay, and loss (like today) but also bandwidth, jitter, etc. The talk will describe the motivation for DIMES, description of our initial results, and our future vision for an Internet that measure itself.
