A mechanism is presented based on a new type of Segment Identifier that 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.
