I am interested in SDN (Software Defined Networking). I believe SDN has a vast potential, especially in making network management much easier. I have been doing research in (and using) OpenFlow since I started my graduate studies. Currently, I am working on Resonance which is a novel dynamic network management framework for campus and enterprise networks, which is implemented with OpenFlow v1.0. More information can be found here.
uCap is a data cap usage management tool for home network users, which uses OpenFlow and OpenWRT. uCap is implemented on top of the BISMark framework, and built with Resonance. uCap passively collects and sends data usage information of each device to the back-end database. Home users can monitor their data usage through a web browser, and also set data usage caps (capacity) for each device. When a device's data usage reaches its cap, the connection will be blocked by the uCap framework.
