Network Service Providers (NSPs) are currently considering to deploy
Content Delivery Networks (CDNs) within their networks. As a
consequence of this development, there is a need for interconnecting
these local CDNs. The necessary interfaces for inter-connecting CDNs
are currently being defined in the Content Delivery Networks
Interconnection (CDNI) WG. This document focuses on the CDNI
Footprint & Capabilities Advertisement interface (FCI).
Specifically, this document specifies a new Application Layer Traffic
Optimization (ALTO) service to facilitate Footprint & Capabilities
Advertisement in a CDNI context.
