Abstract

   This memo specifies the Logging interface between a downstream CDN
   (dCDN) and an upstream CDN (uCDN) that are interconnected as per the
   CDN Interconnection (CDNI) framework.  First, it describes a
   reference model for CDNI logging.  Then, it specifies the CDNI
   Logging File format and the actual protocol for exchange of CDNI
   Logging Files.
