Abstract
A method implemented by a network element (NE), comprising receiving a classification message comprising a classification rule for identifying a service function chain (SFC) in a network, wherein the SFC comprises an ordered set of service functions (SFs) that provides services to an application, and a dynamic application-specific contextual data associated with an operation of the application, receiving a first of a plurality of application data packets, determining that the first of the application data packets matches the classification rule, generating a first SFC packet by adding the dynamic application-specific contextual data to the first of the application data packets according to the classification rule to enable communication of the dynamic application-specific contextual data to at least one of the SFs in the SFC, and sending the first SFC packet towards a next NE according to an SF path in the network associated with the SFC.
