Nanosecond Trading Could Make Markets Go Haywire

"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:
