“Achieving the Dreamvia Soware-Defined Networking (SDN)”


Software-Defined Networking (SDN) is increasingly accepted as the path to achieve cloud computing since SDN allows network inventors and vendors to manage network services through abstraction of lower level functionality by decoupling the system that makes decisions about where traffic is sent (the control plane) from the underlying systems that forward traffic to the selected destination (the data plane). In this session we will present recent work in the area of applying SDN to solve current cloud computing problems at our lab. In particular we will discuss a network-wide service controller which enables multiple networking services to be composed structurally and centrally across physical and/or virtual devices within the network (Service Oriented Architecture, SOA).In order to establish large network systems, e.g., such as Twitter and Facebook, dynamically and efficiently, we propose a structured virtual overlay network over L2which consists of tenant boundary point and cluster-controller. Security is always a main concern for any new emerging technology. We will present a new SDN controller design which will responsible to coordinate security related policies and track the locations of associated objects,e.g., virtual machines (VMs) or files, on the hosting system. Finally, a number of Application cases based on cloud computing will also be illustrated.


Shih Yu Chang (張適宇) is a director of PC Lab in Computer Science Department of National Tsing Hua University, Taiwan. Chang received his B.S., in electrical engineering from National Taiwan University, M.S., in Electrical engineering from University of Southern California and Ph.D. degree in electrical engineering and computer science from University of Michigan, Ann Arbor. He also holds a M.S. degree in Mathematics from University of Michigan, Ann Arbor. In graduate school, he worked on the U.S. Naval Research Laboratory (NRL) project about energy efficient wireless networks and received a best paper award from IEEE IWCMC 2005 for his contributions. After becoming a faculty in National Tsing Hua University, he has published 3 books, 20+ peer-reviewed journal and 30+ conference papers which are most published by IEEE, led 8 PI projects and 4 Co-PI projects, and proposed a framework to generate new ideas mathema cally, namely, invenrelation. He has several certificates for special skill and knowledge domains, e.g., patent attorney, electrical engineering
