Abstract :

Holding residential ISPs to their contractual or legal obligations of
"unlimited service" or "network neutrality" is a hard problem because
ISP traffic management policies are opaque to end users and governmental
regulatory agencies. In this talk I present Glasnost, a system that
improves network transparency by enabling ordinary Internet users to
detect whether their ISPs are shaping flows belonging to specific
applications. I will identify three key challenges in designing such a
system: (a) to attract many users, the system must
have low barrier of usage and must generate results in a timely
manner, (b) the results must be highly accurate to avoid false
accusations of differentiation that adversely affect ISPs' reputation
and business, (c) the system should provide mechanisms to keep it
up-to-date with the continuously changing differentiation policies of
ISPs world-wide. I will describe how Glasnost addresses each of these
challenges in detail.
We have deployed Glasnost in the wild for over a year. During this time
more than 350,000 users from over 5,800 ISPs worldwide have used
Glasnost to test their ISPs, validating many of our design choices.
Using measurement data Glasnost collected, I will present results on the
prevalence of blocking and throttling of BitTorrent traffic in the Internet.

Bio:

Marcel Dischinger is a final year doctoral student advised by
Krishna Gummadi at the Max Planck Institute for Software Systems in
Saarbruecken, Germany. Marcel's research interests span the areas of
networking and distributed systems. In particular, he is interested in
the measurement, analysis, and design of Internet-scale networked
systems. His work focused on characterizing residential
broadband networks at large scale and making ISPs' traffic management
policies more transparent to end users. Also, he recently worked in the
area of monitoring and policy enforcement in cloud computing environments.
