In praise of Software Networks: A Comprehensive Approach
“SDN is here and Görannson’s book will fill a glaring need in the technical education community. It is
a new game in town. This useful reference will help get our students up to speed and ready to play in
this world of immense new possibilities.”
—Brian Capouch, Assistant Professor of Computer Science, Saint Joseph’s College
“This book is THE collection of the state-of-the-art in SDN. Göransson and Black have compiled all
of the current literature into an easy-to-read text, preparing the reader to be both current in SDN tech-
nology and aware of the impact that SDN will have today and tomorrow. This is a must-have on every
network technologist’s shelf.”
—Scott Valcourt, Director of Strategic Technology, University of New Hampshire
“Göransson and Black have truly written a comprehensive book on SDN! This is the book we’ve all
been waiting for. Göransson and Black provide an excellent background on SDN, how OpenFlow plays
an important role in SDNs and how the close alignment with the open source movement has allowed
this technology to progress at lightning speed over the past few years. Anyone who reads this book will
walk away with a detailed understanding of SDN, OpenFlow, the SDN Ecosystem and even the busi-
ness ramifications of implementing SDN. Personally, I can’t wait to use this book with my students in
my SDN course.”
—Robert M. Cannistra, NYS Cloud Computing Center - SDN Innovation Lab School of
Computer Science and Mathematics, Marist College
