The delivery of end-to-end services often requires various service functions including traditional network service functions (for example, firewalls and server load balancers), as well as application-specific features such as HTTP header manipulation. Service functions may be delivered within the context of an isolated user (e.g., a tenant) or shared amongst many users or user groups.

             Problem Statement for Service Function Chaining


   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.
