IMDEA Networks announces the publication of a Patent called “Segment Routing Application Segment”. This is a joint patent between IMDEA Networks (inventor: Pierre François) and Cisco Systems, USA (inventors: Stefano Previdi & Clarence Filsfils).
This invention consists of a mechanism based on a new type of Segment Identifier, which allows operators and large enterprise networks to deploy service chaining without requiring any change in the existing applications. The application segment mechanisms are applicable to both SR-MPLS and SR-IPv6 and address the strongest requirement in terms of service chaining: preserve current applications. This mechanism allows the source (or the ingress node) to apply the service chain, without requiring any configuration or provisioning.
