ii iii ACKNOWLEDGMENTS This dissertation would not have been possible without the tremendous support of my primary adviser Sonia Fahmy and my co–adviser Ness B. Shroff. Their constant encouragement and unwavering support resulted in our publications and ultimately this thesis. During my work, I had to rely on the staff of DETER, Emulab, and WAIL testbeds for my experiments. I am very grateful for their support and patience, in helping me resolve experimental problems. The second half of this dissertation would not have been possible without the help of Michael Blodgett, Prof. Paul Barford, Ron Ostrenga, Terry Benzel, and Prof. Ray Hansen.

I want to additionally thank Michael Blodgett and Prof. Ray Hansen for their help in configuring the routers. Last but not least, I want to thank my family for their constant support and
