I agree Reni; in fact, I had the same argument with the vice-president of
Avici Systems, when I read an article of his on Telecommunications magazine
(http://www.telecoms-mag.com ). The best solution (so far) for IP
QoS seems
to be the MPLS standard.I believe that right now only ATM can
give real QoS
(using CBR Class Of Service) and as I said to my earlier posting
ATM is here
to stay in the backbone, with IP moving down the scale.
As for Gigabit Ethernet, I have read some articles and most of them are
noncommital on the matter of QoS. I just bought a book on it, so as soon as
i study it, i will have a better opinion.
