A new Request for Comments is now available in online RFC libraries. RFC 7498 Title: Problem Statement for Service Function Chaining Author: P. Quinn, Ed., T. Nadeau, Ed. Status: Informational Stream: IETF Date: April 2015 Mailbox: paulq@cisco.com, tnadeau@lucidvision.com Pages: 13 Characters: 28970 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-sfc-problem-statement-13.txt URL: https://www.rfc-editor.org/info/rfc7498 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. INFORMATIONAL: This memo provides information for the Internet community.
