Writing the book on software-defined networks
CRC Press is pleased to announce its newly published book, Building the Network of the Future: Getting Smarter, Faster, and More Flexible with a Software Centric Approach by John Donovan and Krish Prabhu.
Great explorers do more than just venture into the unknown. They also bring back maps and guides to show others the path forward. In 2014, AT&T embarked on a journey to rethink how networks are designed and built. Network traffic soared due to smart phones and mobile device popularity. The old network model couldn’t keep up. Throwing more network gear – switches and routers and other bulky devices – at the problem was inefficient and expensive.
Software was the only way forward. Most consumers were already making the hardware-to-software switch. Think of how you’ve replaced your cameras, music players and video game systems with apps on your phone. AT&T decided to do the same thing with their network. They turned routers, switches and firewalls into software apps running on standard servers. It was a first for the telecom industry and the wide area network. It was a difficult expedition into undiscovered territory. But they pulled it off.
Now, they are well on their way towards their goal of virtualizing 75% of their network by 2020. AT&T hit 34% in 2016, and aim to hit 55% this year. Getting there isn’t easy. And many companies don’t have the resources or the time to recreate their path. So they decided to draw a map, which has become their book, Building the Network of the Future: Getting Smarter, Faster, and More Flexible with a Software Centric Approach. The detailed technical blueprint shares valuable lessons we learned on this journey and it’s receiving some high praise. All author proceeds from the book will go to charity.
Urs Hölzle, Senior Vice President of Cloud Infrastructure at Google, said, “Software is changing the world, and networks too. In this in-depth book, AT&T’s top networking experts discuss how they’re moving software-defined networking from concept to practice, and why it’s a business imperative to do this rapidly.”
AT&T Chief Executive Officer Randall Stephenson notes in his foreword to the book that managing the flood of network traffic “might be the single greatest logistical challenge of the 21st century.”
While the book is intended for a technical audience, it’s an important marker on the network journey both consumers and enterprises are on.
