SDN engineered segment routing

Internet has been an essential part of modern society for long time now. Some regulators are even trying to standardize it as utility, meaning it is as vital for our lives as power and water at home. And it is evolving constantly, improving to speeds never imagined in the past decades. Businesses that use internet are evolving as well. New business requirements for their internet traffic are pushing industry and network service providers to come up with new solutions, to address these challenges. Software Defined Networks and Segment Routing is one of these tools that help network service providers to tackle problems existing in the networking world. SDN is already well established paradigm in the industry, making it easier to manage the network. Segment Routing is the source-routing paradigm addressing existing drawbacks of Multiprotocol Label Switching (MPLS) networks in terms of simplicity, scalability and manageability. By reusing and extending existing protocols, Segment Routing enables network providers to transport traffic using specific or custom paths, which is different from normal shortest path. Having ability have such granularity with traffic flows can give network service provider great business benefits. Segment Routing lays the foundation for application engineered routing. It enables one to easily address customer’s dynamic traffic requirements from higher level application.
