The Internet was designed to always find a route if there is a policy-compliant path.
However, in many cases, connectivity is disrupted despite the existence of an underlying …

Obtaining a" snapshot" of the Internet topology remains an elusive task. Existing active
topology discovery techniques and systems require significant probing time--time during …

The Tor anonymity network has been shown vulnerable to traffic analysis attacks by
autonomous systems and Internet exchanges, which can observe different overlay hops …

The study of users' social behaviors has gained much research attention since the advent of
various social media such as Facebook, Renren and Twitter. A major kind of applications is …

Network traffic engineering and anomaly detection rely heavily on network traffic
measurement. Due to the lack of infrastructure to measure all points of interest, the high …

Network operators measure Internet routes to troubleshoot problems, and researchers
measure routes to characterize the Internet. However, they still rely on decades-old tools like …

Network trouble shooting, failure location, and anomaly detection rely heavily on network
traffic measurement data. Due to the lack of measurement infrastructure, the high …

Monitoring the performance of a large network is very costly. Instead, a subset of paths or
time intervals of the network can be measured while inferring the remaining network data by …

Among various types of attacks on an Ethernet network, a" sniffing attack" is probably one of
the most difficult attacks to handle. Sniffers are programs that allow a host to capture any …

We present a comprehensive delay performance measurement and analysis in a large-
scale wireless sensor network. We build a lightweight delay measurement system and …
