Round-trip time (RTT) is a central metric that influences end-user QoE and can expose traffic-
interception attacks. Many popular RTT monitoring techniques either send active probes …

We consider the problem of congestion-aware multi-path routing in the Internet. Currently,
Internet routing protocols select only a single path between a source and a destination …

Of the major factors affecting end-to-end service availability, network component failure is
perhaps the least well understood. How often do failures occur, how long do they last, what …

Cloud computing is the newest computing paradigm that makes computing resources
available over the Internet on a utility costing basis. Cloud computing offers many …

Multihoming is often used by large enterprises and stub ISPs to connect to the Internet. In
this paper, we design a series of novel smart routing algorithms to optimize cost and …

Predicting the throughput of large TCP transfers is important for a broad class of
applications. This paper focuses on the design, empirical evaluation, and analysis of TCP …

We present Wit, a non-intrusive tool that builds on passive monitoring to analyze the detailed
MAC-level behavior of operational wireless networks. Wit uses three processing steps to …

We present a method to jointly optimize the cost and the performance of delivering traffic
from an online service provider (OSP) network to its users. Our method, called Entact, is …

Recently, overlay networks have emerged as a means to enhance end-to-end application
performance and availability. Overlay networks attempt to leverage the inherent redundancy …

We measure Web performance bottlenecks in home broadband access networks and
evaluate ways to mitigate these bottlenecks with caching within home networks. We first …
