How to Value P2P Delivered Content.
Researchers unfortunately are usually researching outside of
known frontiers. That’s why they call it “Research”. Just like the explorers of
old, researchers go forth to prove their premise and as a result are awarded a
Doctorate or a consulting contract.
Unfortunately, because Researchers work in uncharted
territory, so much of their work has to be developed as they go.
A year ago, Chris asked me – “How can we measure the P2P on
the Internet?” He wasn’t talking about the bits per second traffic across the
backbone, he was referring to an as yet un-described ephemeral value proposition.
For example, if you decide to buy a second hand car there is
the “Car-guide”, the “Red-book” valuation, the local mechanic, the blokes at
the pub (who all have an opinion). So getting a feel for what a second hand car
should be worth, what its fuel consumption is and it’s reliability or lack of,
is rather an easy proposition for any serious purchaser.
On the other hand, on P2P networks, it is a rather different
kettle of fish.
1. Is the listed file real or fake?
2. Is it the version that I wanted?
3. What is the quality of the listed file?
4. Will my “device” handle the codec or format once I have
downloaded it?
5. Is there any malware or a virus in it?
6. How much of my monthly bandwidth allowance will I use up
to download this file?
We researched published papers on the topic and came up
short of what we perceived to be the required “Ratings” scheme for an expanded P2P
interactive trading methodology.
Our research has attempted to give each of these items a
value – thusly:
For individual File calculations:
1. F – for Fake = Number +/-
2. V – for perceived customer satisfaction
3. Q – for quality (bps
and pixels) including L+/- for Lossy/Lossless
4. E – for encoding methodology
5. M – for malware/virus inclusion
6. B – Size of file
and we have added three additional factors;
7. N – Network storage cost
8. T — Network Transmission/Transit cost
9. O – Opportunity cost.
For individual Peer review, we add Credibility and History.

By monitoring downloads on the ED2K networks, we have been
able to utilize the above as a P2P file scoring system.
There are two different applications for the scoring system
as we currently apply it.
To calculate a value for the file
To calculate the popularity for the file
We recently reported on Michael Jackson’s Thriller video as
being the most popular Video in Australia
this last week.
That is not quite correct. If we compare it to the recently
aired (Foxtel) program IOUSA, Thriller scores extremely low. However, amongst
its peer group – i.e.: Popular Music Artists, Thriller scored extremely highly.
We consider that our research in this area has led to a
unique scoring methodology that we have called PTVC (Peer Trust Value Cost).
We shall be talking about Peer Trust Value in the future and
how it can impact all facets of internet utilisation, inclusive of content creators,
content owners and of course the most important category, content consumers.
