  CDNI Logging Formats for HTTP and HTTP Adaptive Streaming Deliveries
               draft-lefaucheur-cdni-logging-delivery-00

Abstract

   The interconnection of Content Distribution Networks (CDNs) is
   motivated by several use cases.  CDN Interconnection can be achieved
   through four CDNI interfaces, one of which is the CDNI Logging
   interface.  This document discusses CDNI logging formats for content
   deliveries performed using HTTP or HTTP adaptive streaming.

1.  Introduction

   The interconnection of Content Distribution Networks (CDNs) is
   motivated by several use cases, such as those described in
   [I-D.ietf-cdni-use-cases].  The overall problem space for CDN
   Interconnection (CDNI) is described in
   [I-D.ietf-cdni-problem-statement].  The CDN Interconnection framework
   is defined in [I-D.davie-cdni-framework] and the requirements for the
