Fortunately, we do have the advantage of hindsight and can attempt to
avoid the worst part of the telco industry's carrier agreements. It may
not be easy but it is an essential problem to solve if we want packet
switching IP networks to become the main transport mechanism for
information in the next century.

That's why we need lots of knobs in the routers, and the CPU power, etc.
to back them up. We don't need to convert the entire network in order to
implement usable realtime voice services; we just need to allow for a
portion of the bandwidth to be allocated according to QoS/CoS. There are
many ways this could be done without implementing metering, if the routers
at every point on the path, can control the use of QoS/CoS.

The bottom line is track record.  Not track tearing.  Not track derailing.
But pounding the damn dirt around the track with the rest of us worms.
