[c-nsp] Per packet load balancing with low latency applications

[William]

Hello list,

I've been looking at using per packet load balancing with a couple of
serial links to use with a low latency market data application, in all
the cisco docs they seem to mention how VoIP/Video applications may
chuck their dummy out with packets arriving out of sequence. My
question is what would cause the packets to arrive out of sequence?
And has anyone been in my position before? what was the outcome?

Per packet is going to be used because there will only be one machine
on each end of the link talking to each other.

Any more information/real life experiences on the matter are welcome.

Thanks for your time.

W
