Bio
I am a second year Ph.D. student at Georgia Tech under the supervision of
Professor Nick Feamster.
I am broadly interested in network systems
and technologies, but currently more focused on network performance &
reliability enhancement, network configuration, network management and
security.
I received my B.S in Computer Science from
University of Wisconsin - Madison and M.S from Georgia Tech. In the past, I
have worked as a research engineer in Future
Systems which is a major manufacturer of network & security solutions
in South Korea.
Research Interest
I seek various ways to enhance current network management systems. As
identifying and understanding problem areas in current methods is an
important first step, I collect and analyze configuration files from network
devices (routers, firewalls, switches, etc) deployed in the network to find
interesting characteristics about current network configuration and management methods.
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.
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. 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.
