A team led by Constantine Dovrolis (Computer Science) was named co-winner of the FCC's Open Internet Challenge competition for a paper describing two tools, DiffProbe and ShaperProbe, that measure network performance. Source: PCWorld

The shift away from simple, blended-rate pricing shows the Internet interconnection market maturing--and becoming more efficient, according to Nick Feamster (Computer Science) and colleagues. Source: Ars Technica

Constantine Dovrolis' (Computer Science) winning application, DiffProbe, and the other entries into the FCC Open Internet Challenge will help "ensure that consumers and the marketplace pick winners and losers online, and that websites or applications aren't improperly blocked or slowed," said FCC Chairman Julius Genachowski.

The key to a secure online world of tomorrow? That would be an Internet that spends a bit more time padding its waistline at the protocol buffet, according to Constantine Dovrolis (Computer Science) and his colleagues. Source: Engadget.com

A study by Nick Feamster (Computer Science) and colleagues may have identified a pricing "sweet spot" for Internet transit providers, finding a balance between simplicity and efficiency. Source: Technology Review

In the natural world, species that share the same ecosystem often compete for resources, resulting in the extinction of weaker competitors. Something similar happened as Internet protocols evolved, and Constantine Dovrolis (Computer Science) says designers of tomorrow's Internet would do well to understand it.

When disaster takes down communications infrastructure, text messages through LifeNet could cost 100 times less than when using satellite phones, says graduate student Hrushikesh Mehendale, who worked with Santosh Vempala (Computer Science) to design the system. Source: Huffington Post

"It's just a piece of code that you can have on your laptop or phone," says Santosh Vempala (Computer Science) of LifeNet, the mobile ad hoc networking software he helped create. "Once you have the software, the computers can communicate with each other, and you don't need infrastructure." Source: Fast Company
