Broadband acess network infrastructures, such as cable, DSL, and cellular networks, are being widely deployed. Yet we have very little knowledge about the real world access ISP deployments and we do not understand how well systems or protocols perform over these networks. We attempt to make ISP deployments more transparent by (a) conducting large-scale measurement studies of broadband ISP deployments, (b) designing tools and testbeds that enable researchers to evaluate the performance of systems and protocols in broadband network environments, and (c) designing measurement systems that enable end users to detect middleboxes (e.g., traffic shapers) deployed by their ISPs.

This page lists only our publications related to Internet access networks. To access the datasets, software, systems, and services we developed, please visit our Internet Access Networks Research page.
