Re: [CDNi] Odp.: Re: Odp.: Re: Requesting Marcin Pilarski to share de-dup expt setup and results, ..Re: Draft IETF-85 minutes posted

Hello Marcin,

Thanks for responding.

Are you saying that if you use DRM there is no duplication of contents even
in the
same provider environment.
You mention that you see very small (may be less than 5%) duplications.. is
that when you operate using DRM?
How many CDN operators are interconnected in your setup?
Is it possible to share the details of content distribution and operations
setup
in which your observation
 "*does not match at all"* what we cite  in the slides?

  ===============================================================
http://www.ietf.org/proceedings/85/minutes/minutes-85-cdni
- see slides
- problem of de-duplication explained with 3 scenarios.
- survey up to 60% data stored is duplicated.
*Marcin Pilarski: what are the assumptions behind these numbers because
that *does not match at all what I see in my environment
* .
====================================================================

By the way, there are also a few independent reports and studies which
confirms the
existence of duplicate content even in same operators environment,
and that it  is a non-trivial problem which need attention.

Let us continue the discussing so that we can improve the draft before
IETF86.

Thanks again.

Best.

Bhumip
