High-performance Network Packet Processors
Ever-increasing application of the Internation has raised the needs for security and flexibility in computer networking.
Software-based routers and packet processors are the low-cost solution to make adaptive and flexible network equipment, but the disadvantage is their low performance.
We develope high-performance packet processing platforms by exploiting the full computation power of recent commodity hardware technology—massively parallel processors like GPUs and multi-queue NICs.

Social networking services
How "influence" is "manipulated"?
Social networking services have opened a new dimension in enabling people to stay connected. It is through this grapevine network that today's "influence" is "manipulated". Personal news spread through Cyworld ilchon friends, technical updates through famous blog sites, recommendations through others' actions, malware through various connectivities.
We study the growth and evolution of online social networks in order to answer the following fundamental questions:
- Is the online social network fundamentally different from off-line human network? If so, why and how?
- What mechanisms could stimulate a social network formulation and growth?
- How general is such a mechanism?

Future Internet Design
What is wrong with today's Internet and
How do we want to build it again?
Internet, as it grew out of a simple packet-switched networking idea, has lived up way beyond anyone's expectations.
Now that it is the network onto which all networking services (phone, fax, radio, TV broadcasting, movies) plus new applications are converging, numerous kludges have been added for a quick fix. What would a computer scientist do given a chance to design a new network? This is the time.
Future Internet is a new clean slate approach to draw up a new design for a network that satisfies what today's Internet cannot. We have begun our investigation into fundamental problems that today's Internet cannot address and designs that could turn into real systems

Measurement and Infrastructure Building for
Emerging Media (VoIP/IPTV/VoD and 3G/3.5G/WiBro/DTN)
Today's Internet carries a myriad of applications and network operators are always playing catch-up with the increase and changes in the traffic.
We have conducted an extensive set of measurement experiments to capture the latest trend in the Internet traffic (e.g., UGC video popularity, IPTV over IP-layer multicast, VoIP over WiBro, 3G and 3.5G traffic), and transalted the garnered insight into infrastructure building in order to support the emerging media.
