Content Delivery Networks (CDNs) are frequently used for large-scale
content delivery. As a result, existing CDN providers are scaling up
their infrastructure and many Network Service Providers (NSPs) are
deploying their own CDNs. There is a requirement for interconnecting
standalone CDNs so that their collective CDN footprint can be
leveraged for the end-to-end delivery of content from Content Service
Providers (CSPs) to end users. The Content Distribution Network
Interconnection (CDNI) working group has been chartered to develop an
interoperable and scalable solution for such CDN interconnection.
The goal of the present document is to outline the requirements for
the solution and interfaces to be specified by the CDNI working
group.
Requirements Language
The key words "Must", "Should" and "May" in this document are to be
interpreted in the following way:
o "Must" indicates requirements that are to be supported by the CDNI
protocols in the stated scope (aka "within initial CDNI scope" or
"beyond initial scope"). A requirement is stated as a "Must" when
it is established by that it can be met without compromising the
targeted schedule for WG deliverables, or when it is established
that specifying a solution without meeting this requirement would
not make sense and would justify re-adjusting the WG schedule, or
both.
o "Should" indicates requirements that are to be supported by the
CDNI protocols in the stated scope (aka "within initial CDNI
scope" or "beyond initial scope") unless the WG realizes at a
later stage that attempting to meet this requirement would
compromise the overall WG schedule (for example it would involve
complexities that would result in significantly delaying the
deliverables).
o "May" indicates requirements that are to be supported by the CDNI
protocols in the stated scope (aka "within initial CDNI scope" or
"beyond initial scope") provided that dedicating WG resources to
this work does not prevent addressing "Should" and "Must"
requirements and that attempting to meet this requirement would
not compromise the overall WG schedule.
