As a Network Engineer and a service provider for the past 13 years I offer the following analisis and a recommendation.
I believe Reps. in congress need some education on the extent on the wiretapping controversy. Following the equiptment is quite revealing.
The fact that a direct link fiber optics line was installed in the AT&T facility in San Fransisco is what got me looking into this situation. That much bandwidth indicated a much greater intrution then the government was indicating in it's public statements. According to Mark Klien the AT&T whistle blower the fiber optics line was split and sent into a separate room set up for NSA. The line was attached to a Narus STA 6400. Both the fiber optics line and the Narus filtering equiptment indicate a huge amount of data is being filtered. It is my opinion, the amount of e-mails and other data are huge and far exceed the 3500 individuals admitted to under the Patriot Act disclosure provisions.
This could also lend credence to the contention by AOL and other ISP's that they have not been involved in blocking various e-mail addresses and in some cases URL's being widly reported over the previous two years. This equiptment could accomplish this blocking activity by virtue of it's position siting right at the routing source in AT&T facilities. There is a ton of things they can do situated at the switching teminals hqs.
My recommendation is for congress get the information of the equiptment discribed in the Narus sites listed below and get experts to interperate the capabilities of this equiptment and bandwidth involved. I'm sure these experts will provide the same analisis that this program far exceeds what the administration has revealed thus far and would indicate that censure is far less than what is needed. This is Impeachable activity.
