The PSTN doesn't offer guaranteed end-to-end transmission, and
certainly statmuxes based on expected load.  Looks like similar
capacity planning.

Perhaps you refer to latency.  Most people don't care as long as
HTTP and POP3 latency is "good enough" -- and server response
time is often a substantial consideration.  SMTP really isn't
picky about latency or jitter.

Maybe you mean packet loss.  Most everyone here can recall the
days of 30% packet loss across congested MAE FDDI fabric, but
that went away what seems like eons ago.
