    abstract =  {SFC offers ordered list of service functions applied to packets, include traditional network service functions and application- specific functions. hSFC defines a hierarchical architecture to deploy SFC in large networks, typically spanning multiple data centers or domains. This document complements RFC 8459 to enable SR-based hSFC. This document specifies and categorizes the interactions between upper- level domains and lower-level sub-domains and appends SR-specific support in constructing hSFC.},
