Siamak Azodolmolky - Software Defined Networking with OpenFlow

Siamak Azodolmolky received his Computer Engineering degree from Tehran University and his first MSc. degree in Computer Architecture from Azad University in 1994 and 1998 respectively. He was employed by Data Processing Iran Co. (IBM in Iran) as a Software Developer, Systems Engineer, and as a Senior R&D Engineer during 1992-2001. He received his second MSc. degree with distinction from Carnegie Mellon University in 2006. He joined Athens Information Technology (AIT) as a Research Scientist and Software Developer in 2007, while pursuing his PhD degree. In August 2010, he joined the High Performance Networks research group of the School of Computer Science and Electronic Engineering (CSEE) of the University of Essex as a Senior Research Officer. He received his PhD (with cum laude) from the Universitat Politcnica de Catalunya UPC in 2011. He has been the technical investigator of various national and EU funded projects. Software Defined Networking (SDN) has been one of his research interests since 2010, in which he has been investigating the extension of OpenFlow towards its application in core transport (optical) networks. He has published more than 50 scientific papers in international conferences, journals, and books. Currently, he is with Gesellschaft fr Wissenschaftliche Datenverarbeitung mbH Gttingen (GWDG) as a Senior Researcher and has lead SDN related activities since September 2012. He is a professional member of ACM and a senior member of IEEE.

Whenever I reach the end of a book production, once again I realize that nobody is perfect. I would like to thank the technical reviewers for providing me with fruitful and constructive feedback. Any remaining errors are, of course, my own. I would also like to thank the Packt Publishing team who has been really supportive in getting this book off the ground. The knowledge, support, and experience of many colleagues in the SDN community have been instrumental in filling the gaps in my understanding of SDN. This book was not simply possible without them.

Finally, sincere and especially heartfelt thanks go out to my son, Parsa Azodolmolky . His patience during writing time, while being away from me is greatly appreciated. I love you Parsa.

Christian Esteve Rothenberg , has been an Assistant Professor at the University of Campinas (UNICAMP) since August 2013, where he received his PhD in Electrical and Computer Engineering in 2010. From 2010 to 2013, he worked as a Senior Research Scientist in the areas of IP systems and networking at CPqD R&D Center in Telecommunications, Campinas, Brazil. Christian was the technical lead of OpenFlow/SDN activities that resulted in RouteFlow and the first open source OpenFlow 1.2 and 1.3 software toolkits.

He holds a Telecommunication Engineering degree from the Technical University of Madrid (ETSIT-UPM), Spain, and an M.Sc. (Dipl. Ing.) degree in Electrical Engineering and Information Technology from the Darmstadt University of Technology (TUD), Germany in 2006. Christian holds two international patents and has published in scientific journals and top-tier networking conferences, such as SIGCOMM and INFOCOM. Since April 2013, Christian has been working as a Research Associate of the Open Networking Foundation (ONF).

Seungwon Shin has recently graduated in Computer Engineering from the Texas A&M University. His research topic was Software Defined Networking (SDN) Security. He has published more than 15 papers in academia and developed open source SDN security tools, FRESCO and FortNOX (and also, SE-FloodLight). Currently, he is working at Atto-Research, Korea, a startup company developing robust and secure OpenFlow controllers.

Preface

Decoupling the network control out of the networking devices is the common denominator of Software Defined Networking (SDN). SDN is a recent paradigm shift in computer networking, where network control functionality (also known as control plane) is decoupled from data forwarding functionality (also known as data plane) and furthermore the split control is programmable. The migration of control logic, which used to be tightly integrated in networking devices (for example, Ethernet switches) into accessible and logically centralized controllers, enables the underlying networking infrastructure to be abstracted from an applications point of view. This separation paves the way for a more flexible, programmable, vendor-agnostic, cost effective, and innovative network architecture. Besides the network abstraction, SDN architecture will provide a set of Application Programing Interfaces (APIs) that simplifies the implementation of common network services (for example, routing, multicast, security, access control, bandwidth management, traffic engineering, QoS, energy efficiency, and various forms of policy management). As a result, enterprises, network operators, and carriers gain unprecedented programmability, automation, and network control, enabling them to build highly scalable, flexible networks that readily adapt to changing business needs. OpenFlow is the first standard interface designed specifically for SDN, providing high performance, granular traffic control across multiple networking devices. This book looks at the fundamentals of OpenFlow, as one of the early implementations of the SDN concept. Starting from OpenFlow switches and controllers up to the development of OpenFlow-based network applications (Net Apps), network virtualization, OpenFlow in Cloud Computing, and a summary of active OpenFlow related open source projects are topics, which are covered in this book. If you are still hungry for more, this book shows you how to do SDN with OpenFlow.
