Abstract

   This document describes a Hybrid Hierarchical Multi-Domain Service
   Function Chaining (hhSFC) architecture that extends Service Function
   Chaining (SFC) to multiple domains with different technology,
   administration or ownership.

   The goals of Hybrid Hierarchical SFC are to reduce the complexity of
   the control plane in a single domain and make the negotiation
   between different domains possible.

1. Introduction

   Service Function Chaining supports customer traffic passing through
   an ordered list of functions as required.

   The [I-D.ietf-sfc-nsh] creates a service plane via Network Service
   Headers (NSH), which provide data-plane information to construct
   service paths and transfer metadata.

Internet-Draft  Hybrid Hierarchical Multi-domain SFC      October 2016

   The document [I-D.ietf-sfc-control-plane] describes requirements for
   conveying information between SFC control plane and data plane in a
   SFC-enabled domain. The document [I-D.dolson-sfc-hierarchical]
   proposes a hierarchical SFC for multiple domains, which are
   controlled by a single organization and trusted by each other, and
   focus on data plane. [I-D. unify-sfc-control-plane-exp] provides an
