Why is Long Range Order Important?
Many aspects of Network Quality of Service depend on coping with peaks that might cause rare events
- cell/packet loss and queue overflow;
- violation of delay bounds, e.g. in video
- worst cases in statistical multiplexing
Poisson processes are well behaved because they are stateless, and peak loading is not sustained, so queues do not fill
With long range order, peaks last longer and have greater impact - the equilibrium shifts for a while.
