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.
