This document provides an overview of the issues associated with the
deployment of service functions (such as firewalls, load balancers,
etc.) in large-scale environments. The term "service function
chaining" is used to describe the definition and instantiation of an
ordered list of instances of such service functions, and the
subsequent "steering" of traffic flows through those service
functions.
The set of enabled service function chains reflects operator service
offerings and is designed in conjunction with application delivery
and service and network policy.
This document also identifies several key areas that the Service
Function Chaining (SFC) working group will investigate to guide its
architectural and protocol work and associated documents.
This document is a product of the Service Function Chaining Working Group of the IETF.
