Abstract:
Recent explosive growth of content delivery/distribution networks
(CDNs) and their interconnection are causing unintended repetition of
content storage in the same dCDN. This can be avoided by using a
suitable de-duplication mechanism. This document explores the
scenarios which create the problem, and then discusses the approaches
to eliminate the duplicated transmission of the same content from
uCDN(s) to dCDN in CDNi networks. To implement the optimization,
some enhancement to the CDNi metadata model and interface is
required.
We realize that for business-specific purposes the same content may
be encrypted/packaged with different keys for different providers.
The impact of DRM (Digital Rights Management) technology on de-
duplication will be discussed in a future version of this draft.
