Internet and various computer networks are at the heart of the explosive growth of communication services and applications that are seen all around us. This fact has always fascinated me and has inspired me to undertake research in the area of Computer Networking. The unprecedented growth in the number of users and devices is placing an increased demand on servers. This motivated me to undertake research to evaluate the performance of servers in Internet. Performance evaluation of servers is a broad area of research. As part of my research, I developed specific methodology and made several key contributions. The research ranged from evaluating specific application layer protocol, to tuning underlying OS software, to configuring the hardware to a specific setting. The finding and methodology developed in my research can serve as a basis for further advancement of research for this topic and can help Cloud operators in capacity planning and maximizing the performance of their networks.
