between two (or more) points in a network and give those points the
appearence of dedicated bandwidth.  In other words, the holy grail of
real QoS would would have the appearence of two computers with a
physical wire between them.

The challange is to provide this level of QoS in a shared, or at least
stistical basis.    Quality of Service can mean many things - poor service,

good service, best service.  It can mean that one type of traffic gets
through the network before another type on a priority basis.
While priority helps, the QoS issue for the internet is one of
delay/latency and jitter, something interactive voice and video
does not well tolerate.

If QoS does not exist, buffering at the receiver is often the only
recourse.
