Research Briefing

My interest in characterizing and modeling the wide-area network behaviors started from studying network anomalies. Later I participated a collaborating project. The goal was to develop realistic models that can be used for performance evaluation of network protocols and applications. I have also been very interested in location-aware network protocols. Locations of network hosts are very important in many scenarios. Geographical information is indispensable in systems such as E911. Due to the limitations of the GPS system, many alternatives such as virtual embeddings are proposed to work in place of geographical coordinates. Recently, I did some work on optimizing packet I/O of multi-core systems. Packet I/O is a bottleneck in high-speed packet processing on a general purpose computing platform despite the increase in CPU performance. When more and more multi-core processors become available in the market, it is appealing to investigate if we can take advantage of the multiplied hardware resources to improve packet I/O.
