Abstract
Embodiments of the present disclosure describe a self-contained service function network layer between a chain (e.g., a logical chain or service function chain) and a substrate network. Embodiments of the present disclosure further provide techniques for constructing logical chains for service function networks using chain tables, organizing chain tables using application program interfaces (APIs), deploying service function networks to substrate networks, routing packets through a service function network and a substrate network, and inserting, deleting, re-routing, moving and substituting service functions in logical chains.
