To what extent do CDN caches deep inside the ISP or the operator network also improve QoE? Does it suffice to simply deploy the CDN appliance just past the peering point? This blog post describes a project, sponsored by Cisco’s Research and Open Innovation initiative, and undertaken by Prof. Sanjay Rao, his graduate student Ehab Ghabashneh at Purdue University, and that I had the privilege of advising, to explore this very question.

A new tool from Purdue University researchers may help stop cyberattacks. The Purdue team created a detection system to alert organizations to cyberattacks. The system is called LIDAR – which stands for lifelong, intelligent, diverse, agile and robust. “The name for this architecture for network security really defines its significant attributes,” said Aly El Gamal, an assistant professor of electrical and computer engineering in Purdue’s College of Engineering.

Can a drone determine the shape of a room using microphones alone? That’s what Purdue University researchers set out to discover in a study that will be published next week in the SIAM Journal on Applied Algebra and Geometry. In it, they propose a drone-mounted microphone array that measures sound emitted by a loudspeaker to inform a digital reconstruction of the physical surroundings.

The Trask Innovation Fund has awarded a total of nearly $81,000 to two Purdue University researchers to help them commercialize their innovations. The fund, established in 1974, helps support technology and innovations that are being commercialized through the Purdue Research Foundation.
