Internet sampling and
measurement
Abstract
Sampling Internet structure and its service availability have always been
important issues in Internet research. This project aims to develop mechanisms
for discovering available services in the Internet using scalable end-to-end
measurements, facilitate delay sampling between arbitrary hosts using the
existing DNS infrastructure, perform more accurate bandwidth estimation, and build router-level maps of the Internet using
non-intrusive traceroute to known destinations. We are also working on techniques
for fingerprinting OS and server implementations using low-overhead end-to-end
methods.

Datasets
OS fingerprinting results from the IMC 2010 paper are available below. This
includes 98 signatures, modified snacktime algorithms, and all SYN-ACK RTOs from
an Internet-wide scan on port 80 in August 2009. To cite the data and/or
algorithms, please use the IMC paper above and refer to dataset HTTP2.
