Praise(s)

“A fault-tolerant network is a must in our healthcare environment. Junos High Availability will serve as a great tool to help us maintain the high availability our clients have come to expect.”

James Hardy, Network Engineer, Carilion Clinic

“I like that Junos High Availability is reality-based. It boils buzzwords like redundancy and high availability into models that have design and cost. And the book is not marketing fodder—it does a good job of identifying the Juniper Networks hardware and Junos OS features that influence HA, together with a lot of good information on Juniper architecture in general. The configuration examples are useful, and the sections on the Junos XML API and JUNOScript API stir up all sorts of creative ideas in the mind of someone with even a little bit of scripting experience.”

Dan Schmiedt, Chief Network Engineer, Clemson University

“Junos High Availability has exactly what my customers need to know in order to build and maintain continuously available network systems. It is the book to read for those responsible for any mission-critical network.”

Robert F. Jaeger, Systems Engineer Manager, Juniper Networks

“Junos High Availability provides the reader with the knowledge to design and configure his network away from default settings toward a better design that provides rapid convergence, increased scaling, and a resilient architecture. Both network architects and operators will find value in the lessons taught within this book.”

Tom Scholl, Principal IP Network Engineer, IP/MPLS Backbone Design & Development, AT&T Labs

“Junos High Availability contains all the technical building blocks necessary to plan and maintain a medical grade network.”

Jonathan Yantis, Network Engineer, Medical University of South Carolina

“At Townsend Analytics our trading clients, using our RealTick trading suite, demand that our global network maintain an extremely high level of availability. Downtime translates directly into lost money. Junos High Availability has great tips and guides to help support this environment. It includes everything from conceptual details on software and hardware, very detailed routing protocol examples, security and auditing, and everything in between. This book is a must for anyone who is in any way involved in maintaining a high level of service on their network!”

Chris Rizzo, Senior Network Engineer, Townsend Analytics

“High availability is such a buzzword these days. It’s refreshing to see an approach that breaks down all of the various conversations and shows what is required for an overall continuous system. Getting the building blocks right is crucial to having a network that is truly highly available, and Junos High Availability will help you get it right and keep it right.”

Scott Stevens, Vice President, Technology, Juniper Networks

“With disaster recovery and business continuity the current buzzwords in our state government network as well as in most corporate networks around the world, this book has come along at the perfect time to spur conversations on high availability, not only for networks built on Juniper Networks equipment, but on other vendor equipment as well. The topics covered in Junos High Availability are broad enough for engineers looking to design an overarching high availability posture in their network, but also detailed enough to allow engineers to implement their designs through protocol tweaks and Junos tools. The transition between authors keeps topics interesting and provides amusing quips along the way.”

Aaron Robel, Systems Engineer, Washington State Department of Information Services

About this Book

Whether your network is a complex carrier or just a few machines supporting a small enterprise, Junos High Availability will help you build reliable and resilient networks that include Juniper Networks devices. With this book’s valuable advice on software upgrades, scalability, remote network monitoring and management, high-availability protocols such as VRRP, and more, you’ll have your network uptime at the five, six, or even seven nines -- or 99.99999% of the time.

Rather than focus on “greenfield” designs, the authors explain how to intelligently modify multi-vendor networks. You’ll learn to adapt new devices to existing protocols and platforms, and deploy continuous systems even when reporting scheduled downtime. Junos High Availability will help you save time and money.

  • Manage network equipment with Best Common Practices
