Networking and Multimedia Systems Lab (NMSL)

Baek-Young Choi, Ph.D., coordinates the Networking and Multimedia Systems Lab (NMSL) in the School of Computing and Engineering. Choi and her team conduct research in the areas of communication networks and distributed systems. The lab focuses on algorithmic solutions for measurement and analysis of network traffic, performance and reliability, to network design, routing and resource optimization of various network types. The team investigates innovative ideas in support of bandwidth-intensive multimedia applications, and for building efficient and flexible future networks. Below are some of the current funded projects.

On Optimization Issues in Supporting High Bandwidth Multimedia Applications

Principal Investigator(s): Baek-Young Choi, Ph.D.
Funded by: National Science Foundation, $191,000
Goal: Despite the success of the Internet, its bandwidth over-provisioning, redundancy in its connectivity, and increased understanding of operation, continuously emerging bandwidth-intensive applications however, presents the need of efficient network support. Particularly, it is increasingly pressing for network design to facilitate imminent proliferation of high bandwidth one-to-many applications in an efficient and scalable manner, such as web cache updating, transfer of software upgrade, IPTV, and live lecture to a group of distributed participants. The project aims to design, implement and evaluate network architecture for one-to-many high bandwidth applications through multiple layer perspectives toward achieving optimal resource usage, performance and reliability.

Efficient and Adaptive Access Network Resource Management and Monitoring

Principal Investigator(s): Baek-Young Choi, Ph.D.
Funded by: University of Missouri Research Board, $27,000
Goal: The main performance bottleneck today’s Internet is often at the first or the last mile access networks. This project addresses challenging access network issues, such as wireless resource management, cross-layer cooperative methodologies to adapt to the diverse and varying characteristics of the access network and access network monitoring.
