RE: IP QoS issues

Masataka,

I agree with Karl that IP QoS is still quite a long way off. It's not as
easy as reusing ATM techniques. Instability of routes is bound to maintain
QoS difficult and it's not a solved problem.

Thanks

Not so much. Techniques developped for ATM can be reused.

Those are the misunderstandings which is acting as the major
obstacles on the short way.

A solved problem.
