Nanosecond Trading Could Make Markets Go Haywire http://www.wired.com/wiredscience/2012/02/high-speed-trading/

"Below the 950-millisecond level, where computerized trading occurs so quickly that human traders can't even react, no fewer than 18,520 crashes and spikes occurred."

Anyone who has managed a network knows that when you look at your MRTG/Cacti graphs at 5min, 10min ,15min intervals - all looks well. Start looking at 1sec intervals and you will see spikes that hit 100% of capacity - even on networks running at 25% average utilization.

I guess trading and networking do have many unseen similarities.

Tieing the two together, this post shows how a lot of 'conventional' network thinking needs to be turned on its head when it comes to networks for trading floors:
