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:
