The comprehensive guide to design integration in a multi-domain environment providing consistent design across large-scale environments.

Prajapati, Bowman, and Suvarnas more than 50 years of combined customer network-building experience will help you translate your organizations business and technical intent into a fully functioning, secure, and efficient network.

Catalyst SDA, Catalyst SD-WAN, ACI MPLS, CNFs, Cloud, and Security technology domains account for a large market share in consumer networks as a replacement for traditional monolothic networks. Designing Real-World Multi-Domain Networks is designed for architects and engineers who want to integrate these new and emerging multi-domain technologies so you can be at the front of this inevitable network change.

Written with great care, this technical book is divided into three clear sections, guiding readers into the world of blending architecture with technology. Each chapter focuses on a different aspect, explaining how modern technology integrates and interoperates with other architectures.

You have the freedom to choose how you read. You can go through the book from start to finish like a story, or you can jump straight to the parts that interest you the most. The layout is made to be flexible, suiting both those who like to read in order, and those who want quick solutions.

The book ends with five real-life examples, connecting theoretical ideas to practical results. These stories make the lessons clear, giving you the understanding and skills needed for real-world projects.

Understand how Cisco Catalyst SD-Access, Catalyst SD-WAN, ACI, MPLS, CNFs, Cloud, and Security interoperate with each other to form end-to-end segmented and secure networks
Understand details on how a packet behaves as it transits one technology domain to another
Get answers to big what, whys, and hows surrounding multi-domain networks
Learn from actual real-world deployment of Cisco customers
Gain valuable insight from the authors previous large-scale deployments
Utilize reference architecture for using these technologies in tandem
