Traffic monitoring (Was: Reordering, not Latency)

If I were doing global Internet monitoring, I wouldn't be doing it in-band. Too much cooperation by the vendors required; too much discovery. Rather, I'd gain access to the trunks directly and do my own demodulation and decoding.
How would you get access to the trunks? Aren't they mostly optic fibers now? Also, since Internet traffic is growing at a geometric rate, the probability of anyone or any organization having the capacity to monitor and process ALL of Internet traffic should be very small and decreasing. It would be much easier to install sniffers on selected local networks (e.g., those containing remailers or other entities you're interested in).

I can't speak to the current system per se, but slowly things are moving to SONET. A key feature of SONET is that indivual channel like DS-0, OR DS-1 CAN BE BROKEN out without "de muxing" the entire data stream. Basically they have in the "system" a pointer to the memory location of each channel and they can just full that frame out. This is important for a reason I have spoken here before about.. Law Enforcement loves to talk about how digtial tech will make things harder to "tap." When in fact technology like SONET will make it easier. (today to tap into a DS-3 trunk, looking for a DS-0 channel, you need to de-mux and pull out all the DS-1 channels, find the DS-1 that contains the DS-0 you want, and then de-mux that to get into and Tap the DS-0.)
