Problem Statement for Service Function Chaining
RFC 7498, “Problem Statement for Service Function Chaining”, is an Informational document published in April 2015 by P. Quinn, T. Nadeau. The canonical text is published by the RFC Editor.
Abstract
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.
What “Informational” means
