A lot of the Alcatel systems did, I've seen quite a few that used a tractor feed printer to report CDR's haha.

PABX? Surely an office phone system is the analogue NAT?
Though all but dead now.. yet I can't really think of any that stored for 2 years the mapping of when what internal user made what external phone call for how long...

Clearly if you need source and destination of every packet then sFlow just doesn’t cut the mustard.


No network identifier 'cuts the mustard'. They identify a host, or an application the host is using, but not the person behind the device. And in the case of IPv6, they can change periodically, as they have been on Windows boxes every 8 to 12 hours or so.

Telephone numbers might be somewhat accurate analogues for individuals, as there is one phone number per device, and they're not NATted by the carrier or the end-user. The same cannot be said about Internet protocol identifiers.

For cases of copyright violation, US courts have determined that IP addresses is not a person, so why does the crime of terrorism make that any less false?



Also as clear (to us, if not them) if you’re NOT collecting said ‘meta data’ on every single packet then why bother capturing any?

Or are you hoping to capture every N-th terrorist plot, kiddie-porn-ographer or other bogey-man of the moment?
