Nick Feamster presented the Lithium OpenFlow controller at the Open Network Summit in Santa Clara, CA, to over 900 attendees from academia and industry. The Lithium controller allows network operators to express policies that incorporate network characteristics such as time, history, and user, thus allowing operators to express and implement policies that are inherently reactive. Lithium is also the "back end" to the uCap usage cap management system that Feamster and his students have worked on in collaboration with Marshini Chetty and her research group.
Learn more about Lithium:
We're now looking for beta testers of the uCap application, which runs on top of the BISmark home router platform. The routers also perform continuous active measurements of the access ISP performance; here is an example. Please contact Nick Feamster or the BISmark team if you are interested in receiving a BISmark router and trying it out in your home!

Our SIGCOMM 2011 paper, "Broadband Internet Performance: A View From the Gateway", which studies broadband Internet performance from about 4,000 homes in the United States and eight different ISPs, has been selected for Communications of the ACM's Research Highlights, a section devoted to the most important recent computer science research. The article will appear in Communications of the ACM later this year. Congratulations to Srikanth and the BISmark team! Read more about Project BISmark (and get involved!) here.
Bobble "Filter Bubble" Tool Released

We have released Bobble, a Chrome extension to help users visualize how their search results are being personalized. The filter bubble is a concept developed by Internet activist Eli Pariser to describe a phenomenon where websites use algorithms to predict what information a user may like to see based on the user's location, search history, etc. As a result, a website may only show information which agrees with the user's viewpoints. One such example is Google's personalized search results. To "pop" the bubbles created by Google search (also called de-personalization), we have developed Bobble, a Chrome extension that uses hundreds of nodes to distribute a user's Google search queries worldwide each time the user performs a Google search.
