I’ll reply here, since the old debate seems more or less dead.
First, I’ll confess not having read the entire UCLA website, but I came across these passages in the report for the European Parliament, and I quote:
" 55. Routes taken by Internet “packets” depend on the origin and destination of the data, the systems through which they enter and leaves the
Internet, and a myriad of other factors including time of day. Thus, routers within the western United States are at their most idle at the time when
central European traffic is reaching peak usage. It is thus possible (and reasonable) for messages travelling a short distance in a busy European
network to travel instead, for example, via Internet exchanges in California. It follows that a large proportion of international communications on the
Internet will by the nature of the system pass through the United States and thus be readily accessible to NSA. "
While basically true, it’s definitely not accurate. It does not “make sense” to move IP packets twice over the Atlantic if it can be avoided, those lines are expensive. European ISPs interconnect their networks as much as possible and so, I would suppose, do American ISPs. It makes economic sense to do so.
In other words, IP traffic can take many different ways through the network, and Echelon operators would need to plant a LOT of wiretaps to get at even a small proportion of the traffic.
Of course, different IP packets containing data from the same e-mail (or other communication) may be (and often are) transmitted on separate lines, making “scanning” even more difficult. Not only do you have to scan all of the lines, you have to merge the data somewhere - meaning of course, that you have to have a parallel transmission capacity of about the same size as the lines you are monitoring. (Am I making sense at all ?) Of course, I or one of my colleagues could on a whim decide to reconfigure the routers in order to redirect the traffic, making Echelon’s task even harder.
MAN, this post is getting long. What I’m trying to say is: The nature of the Internet makes bugging it on a larger scale a hard task, not an easy one. (On a lighter note, I might add that the nature of most Internet engineers would cause them to yell bloody murder if they suspected foul play on what they consider their private playground.)
About the phone network, I’ll admit to being ignorant - any telco engineers out there ?
Being worried is the thinking man’s form of meditation.
