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