incorrectly
asserted that because P2P DPI and caching is doable that it suddenly is
easy to
classify the CONTENT according moral standards.<br>
P2P DPI and caching doesn't have to do nearly the same work.<br>
<br>

style="font-size: 10pt; font-family: Arial; color: navy;">Again MMC –
you are putting words in
my mouth. I said that it would be quite capable of intercepting a
‘flow’
and assess whether that portion of flow is on the ‘list’. I
wasn’t saying you should intercept the flow, reconstruct it get some
intelligent
software to consider it’s classification based on the number of flesh
colored pixels and moaning. Are you suggesting that with the current
P2P
caching systems out there they can’t determine the file (or portion
thereof) from the flows so it can provide a locally cached copy of it?
Seriously? Then how does a P2P caching system work? It just inserts
some locally cached content randomly in the hope that it’s the same as
being sought? Of course not. Based upon flows it can identify what
is actually being transmitted and then it substitute it’s local copy.</span></font></p>

(1) The DPI identification works statistically - doesn't need to look
at content just flows and then pass it off to the caching side of
things.<br>
(2) The analysis (identifying a file) only works on a subset of flows
(ie. not on HTTP).<br>

style="font-size: 10pt; font-family: Arial; color: navy;">The
difference here MMC is that it doesn’t
CLASSIFY the CONTENT, it IDENTIFIES the FILE and checks it against a
list.</span></font></p>

Yep.<font color="navy" face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial; color: navy;"><o:p> Much
easier than having to look at each flow and classify content by morals.
</o:p></span></font>It's just a list of hashes you've cached.<br>
<br>
As you said before:<br>
<br>
"It is PRACTICALLY impossible to guarantee a clean feed. If you can't
guarantee a clean<br>
<pre wrap="">feed, then you are providing parents with a false sense of security
thinking they have."
Why? Because no one's developed a good, line rate, classify all content by morals system. Because it's HARD.
