System to Manage Usage Caps in the Home at SIGCOMM, GENI, Open Network Summit

Joon Kim, Srikanth Sundaresan, Marshini Chetty presented an OpenFlow-based system called uCap to help users manage their home network usage.  With UCap, users and devices in the home network can be allotted “caps” – a fixed volume of data per month, and this cap is enforced by the home router. With limited usage the norm in many parts of the world and recently in the US, such a system allows the user control over their Internet.

The system is a collaboration between the GTNoise group and human-computer interaction researchers at Georgia Tech.  The back-end system uses a custom OpenFlow controller that is especially designed for processing network events.  The front-end is an HTML5 Web interface that allows users to easily view and manage their home usage.




uCap has also been demonstrated at the following conferences:


  • The 12th GENI Engineering Conference, November 2011
  • The Open Networking Summit at Stanford University, October 2011
  • Broadband2020, Georgia Tech, October 2011
  • GVU Research Day, Georgia Tech, October 2011
