                   Intra-CDN Provider CDNi Experiment
         draft-chen-cdni-intra-cdn-provider-cdni-experiment-02

Abstract

   In [RFC6770], the Inter-Affiliates CDN Interconnection use case is
   described.  In this scenario, a large CDN Provider may have several
   autonomous or semi-autonomous subsidiaries that each operates on
   their own CDN.  The CDN Provider needs to make these down-stream CDNs
   interoperate to provide a consistent service to its customers on the
   whole collective footprint.

   This document illustrates in details the CDNi experiment that has
   been carried out by China Telecom, and the lessons and experiences to
   CDNi standardization work.
