for both unicast and multicast environments. Research assistant advised by Mary Vernon. Workload Characterization of Streaming Media Servers - With the goal of further understanding client behavior and designing more realistic workload models to drive the development of more efficient caching strategies, I am cur- rently analyzing logs from different streaming media servers, looking into char- acteristics such as file popularity and client interactivity. Research assistant advised by Mary Vernon. Peregrine - participated in the design, implementation and performance testing of Peregrine, a high performance proxy server, with emphasis on the storage subsystem, intercommunication between proxies and kernel optimization and profiling. Research assistant advised by Pei Cao. Wasp - developed a benchmark for Web servers that emulates WAN character- istics, such as network delay and packet loss, in a local area network. Summer internship at IBM T.J. Watson. Summary Cache - participated in the design and analysis of a new scalable cache sharing protocol that significantly reduces CPU overhead and bandwidth consumption while still maintaining almost the same cache hit ratio as the pre- viously proposed and widely deployed ICP protocol. Research assistant advised by Pei Cao. Wisconsin Proxy Benchmark (WPB) - developed a distributed multipro- cess benchmark that can be used to compare the performance of various proxy products and predict their behavior in real-life situations. Several proxy servers were analyzed based on the results collected by the benchmark. Research assis- tant advised by Pei Cao. Quality-of-Service Web Content Hosting - analyzed the impact of priority- based process scheduling on the performance of a Web Server. Using Linux and Apache server as the testbed, this project involved an analysis of the effectiveness of process prioritization in providing different levels of quality of service. Two schemes were implemented: one at the kernel level and the other at the user level. Course project for CS736 (Advanced Operating Systems) Multi- and Unicast Over a Reliable Link Layer - Designed and imple- mented a reliable link layer protocol and a network layer protocol that support multicasting.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
