[from somelist] -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 That's what it appears we are up against, folks. Real-time semantic data monitoring on a huge scale. A scale beyond what most of us can even comprehend.

I've sent away for their white papers (and have yet to get a reply --- I suspect they've been dailykossed), but I suspect that they're using the word "semantic" at a far lower level than people are accustomed to thinking. You have to understand that all you users just exist to provide a test load for our network. If you spend your life at layer 2 of the network (down where packets change direction based on the value of a few bits in the IP header) then looking beyond the IP header (to such exotic places as the port numbers in the TCP header) to recognize that one packet as likely to be HTTP and another as likely to be VOIP is considered "semantic". And it's harder than you'd think it would be at 10Gbps (that's one packet roughly every 200 nanoseconds). One of the reasons I am dubious about this article is that the peering point that tries to do intrusion detection between what we used to refer to as "the Milnet" and the rest of the world is unable to monitor packets on 1Gbps links (so they keep adding 1Gbps links every couple of months instead of adding 10Gbps links less frequently). That site has hardware money coming out its ears (they talk about keeping several hundred gigabytes of transaction logs in RAM). And, that site is run in cooperation with NSA. If this equipment did what is being claimed, I think that peering point would know about it and be using it for lesser things like intrusion detection. ---p*zz*] ----- End forwarded message ----- -- Eugen* Leitl <a href="http://leitl.org">leitl</a> http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://www.ativel.com 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE [demime 1.01d removed an attachment of type application/pgp-signature which had a name of signature.asc]
