                         CDNI Logging Interface


   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.

1.  Introduction

   This memo specifies the CDNI Logging interface between a downstream
   CDN (dCDN) and an upstream CDN (uCDN).  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.

   The reader should be familiar with the following documents:

   o  CDNI problem statement [RFC6707] and framework [RFC7336] identify
      a Logging interface,

   o  Section 8 of [RFC7337] specifies a set of requirements for
