how wonderful to read an article about networking and not see "Cisco" mentioned once.
Not that I have anything against Cisco, but it is most certainly not a Cisco-only world, despite what your network manager would tell you...
In a real-time system ...
150 ms is an infinity of latency. It all adds up, y'know!
No. Stupid fatal error.
For god's sake, it's only been a few years since the last meltdown caused by automated trading systems running away in a positive feedback spiral. Anyone who knows anything about economics and about cybernetic control mechanisms would see in an instant that a bit of packet delay is a *good* thing; it amounts to putting some damping on the feedback loop.
Re:No. Stupid fatal error.
Err, no. When you're running big arbitrage positions it's the delay that causes the problems.
As for "a meltdown caused by automated trading systems running away in a positive feedback spiral" I think you'll find that shit coding and stupidity cause problems wherever they surface but it doesn't mean that things shouldn't advance, just that people should take more care over what they do.
@Stupid Fatal Error
Sure, you go ahead and have some dampening latency, and I'll arbitrage you out of business.
They're talking microseconds not milliseconds so it's actually only a thousandth of an infinity.
A 150 ms may be a lot in a real time system. But we're talking about 150uS only a factor of a thousand faster.
That's good then. Apologies for the misread.
