Content Distribution Internetworking BOF (cdnp)

Tuesday, December 12 at 1545-1645
=================================

CHAIR: Mark Day <markday@cisco.com>

DESCRIPTION:

Problem to be solved:

There are a number of content distribution networks (CDNs) deployed and/or
planned. Consistent with the general history of internetworking, people are
starting to think about ways to interconnect these different CDNs, and
talking about "peering at the content level", "CDN peering," or "content
peering." Regardless of name, the goal is to allow different CDNs --
implemented using differing technology or under different administrative
domains -- to cooperate with each other, forming a larger "virtual CDN."

Outline of proposed solution:

Recent discussions have proposed treating a CDN as containing a direction
system, a distribution system, and an accounting system.  The proposed
approach to CDN interoperation is through supporting the transfer of
information between the corresponding systems of two peered networks.  We
propose the development of three protocols or protocol families, one for
each of the kinds of systems that can be peered.
