Segment Routing: Foundation for Application Engineered Routing

by Kris Michielsen, Clarence Filsfils

As your customers increasingly run massive numbers of diverse new cloud-based applications, more sophisticated application and network interaction will be crucial to your success. Whether you're in an enterprise, service provider, or Over-the-Top (OTT) environment, your network will need to understand application needs, and establish end-to-end per-flow policies that integrate data center, WAN, and end-customers in scalable, stateless, and simple ways. Segment Routing (SR) makes this possible. Now, there's an expert introduction to SR fundamentals, functionality, and deployment, straight from the technology pioneers who've helped to create and standardize it. Authors Kris Michielsen and Clarence Filsfils explain SR's goals, drivers, architecture, innovations, and implementation, illustrating key concepts with the real use cases that have shaped this technology. They interview key operators who helped drive the original definition of Segment Routing and Cisco's Application Engineered Routing (AER), while also presenting practical examples of Segment Routing at work in other environments. You'll discover how SR improves network simplicity, scalability, agility, consistency, and programmability, while overcoming long-time pain points of existing IP and Multiprotocol Label Switching (MPLS) networks."
