V. Hollot, Department Head Electrical and Computer Engineering To my beloved parents. Many thanks to Professor Tilman Wolf. ACKNOWLEDGMENTS First of all, I would like to express my sincere appreciation to my advisor Prof. Tilman Wolf for his invaluable guidance during the project and his instruction on my work. Then I would like to thank PhD student Mr Xinming Chen, who offered plenty of zealous help and his suggestions that helped me to reach the final design of the probe. I will also give my gratitude to PhD student Mr Abhishek Dwaraki. Without his help of database design and service specification, I know I cannot reach next stage of the project. In addition, the PhD students Mr Jiahui Jin, Ms Samamon Khemmarat and Mr Guoyi Zhao provide me a lot of useful advice on my project. vi ABSTRACT DESIGN AND IMPLEMENTATION OF A NETWORK SERVICE MARKETPLACE SEPTEMBER 2014 YUNSHENG QI B.Eng., TIANJIN UNIVERSITY M.S.E.C.E., UNIVERSITY OF MASSACHUSETTS AMHERST Directed by: Professor Tilman Wolf The Internet has successfully served the world for more than three decades, while limitations and drawbacks still exist. A lot of researches have been done on inno- vation of Internet to address those inadequacies. One approach to improve Internet performance is to make choice as a principle in network architecture. We believe that a service-based network architecture with choice, or we call it ChoiceNet, is the most suitable option for future Internet. In this thesis, we design and implement a network service marketplace. Due to the flexibility and functionality of web application, the marketplace is implemented by a web application to fulfill functions such as storing and searching network services, handling actual financial transaction and interacting with client and service planner. vii TABLE OF CONTENTS Page ACKNOWLEDGMENTS ............................................. vi ABSTRACT ......................................................... vii LIST OF TABLES .................................................... xi LIST OF FIGURES.................................................. xii CHAPTER 1.
