Content Delivery Network Interconnection (CDNI) Request Routing:
Footprint and Capabilities Semantics
Abstract
This document captures the semantics of the "Footprint and
Capabilities Advertisement" part of the Content Delivery Network
Interconnection (CDNI) Request Routing interface, i.e., the desired
meaning of "Footprint" and "Capabilities" in the CDNI context and
what the "Footprint & Capabilities Advertisement interface (FCI)"
offers within CDNI. The document also provides guidelines for the
CDNI FCI protocol. It further defines a Base Advertisement Object,
the necessary registries for capabilities and footprints, and
guidelines on how these registries can be extended in the future.
