Title: Request Routing Redirection Interface for
Content Delivery Network (CDN) Interconnection
Author: B. Niven-Jenkins, Ed.,
R. van Brandenburg, Ed.
Status: Standards Track
Date: October 2016
I-D Tag: draft-ietf-cdni-redirection-20.txt
The Request Routing interface comprises (1) the asynchronous
advertisement of footprint and capabilities by a downstream Content
Delivery Network (CDN) that allows an upstream CDN to decide whether
to redirect particular user requests to that downstream CDN; and (2)
the synchronous operation of an upstream CDN requesting whether a
downstream CDN is prepared to accept a user request and of a
downstream CDN responding with how to actually redirect the user
request. This document describes an interface for the latter part,
i.e., the CDNI Request Routing Redirection interface.
This document is a product of the Content Delivery Networks Interconnection
Working Group of the IETF.
This is now a Proposed Standard.
STANDARDS TRACK: This document specifies an Internet Standards Track
