Add in the fact that optical sniffing, while not impossible by any means today, will increasingly become non-trivial as bandwidth increases. Which is exactly one of the 'problems' they expect optical network to solve.You mean just expensive, right? i.e. a couple transponders and an OC48 or OC192 switch.
Cost is a factor, certainly, but the storage of the captured data becomes the larger problem. In the TB or PB range of optical data transmission, where and how do you store the captured information? Unless you have TB's of solid state drives to stream electrons into after an optoelectronic photon -> electron conversion your only other option is to store the photons in loops of fiber with an optical repeater. Until we have quantum computers which might be able to parse the data in real-time, we still need a buffer to store the data in before we can look for the needle in the haystack. Even with some nifty filtering on the sniffer, you're potentially looking at obscenely large amounts of information to store. I would expect that the distance of fiber you will need to store the data in will be the gating factor, which means it tilts more towards a physical issue than a cost issue. If I need a few thousand kilometers of fiber as a storage loop, it's kind of hard to move around efficiently. :-) Regards, Chris Kilbourn Founder _________________________________________________________________ digital.forest Int'l: +1-425-483-0483 where Internet solutions grow http://www.forest.net
