Internet Engineering Task Force (IETF) F. Le Faucheur, Ed. Request for Comments: 7937 Category: Standards Track G. Bertrand, Ed. ISSN: 2070-1721 I. Oprescu, Ed. R. Peterkofsky Google Inc. August 2016 Content Distribution Network Interconnection (CDNI) Logging Interface Abstract This memo specifies the Logging interface between a downstream Content Distribution Network (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. Status of This Memo This is an Internet Standards Track document. This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Internet Engineering Steering Group (IESG). Further information on Internet Standards is available in Section 2 of RFC 7841.
