Foreword

It’s a great pleasure for me to write the foreword for the first complete guide to SD-WAN. Being the founder of Viptela (Cisco SD-WAN), I am delighted to read a really comprehensive work on SD-WAN. SD-WAN is one of the major disruptions wide area networks have seen since MPLS was created in the 90s.

Since SD-WAN requires people to understand both technology and implementations of the new age WAN, I feel this book will provide a great reference guide for the reader. The topics covered will benefit both the novice and expert reader. Because this book is structured to walk you through from basic principles to advanced topics, it can be used as a reference guide.

This book is written by a team of individuals who have been instrumental in deploying and testing the largest SD-WAN networks.

I would strongly recommend reading this comprehensive book on the Cisco SD-WAN networking technology.
