I can set up a Gigabit desktop switch, plug in server and some workstations, and run them through VoIP phones generating 96Kb/s audio streams, and cause the audio streams to break down in quality - even though the pipes are considerably larger than the traffic I am trying to protect. I suspect shifting to 10Gb/s pipes would make no difference. So I'll stay with the contention it doesn't matter how big the pipes are, QoS can be used to provide delay, latency, jitter (and loss) guarantees to make applications work properly. But this is for private networks, not the Internet. And I do agree, the Internet is not "policable" to allow QoS to work. It's the very principle of the Internet. :-) -----Original Message----- From: Joe Abley [mailto:jabley(a)hopcount.ca] ...
I've never ran into a case where the "pipes" where so big that QoS was not required. Never.
That's presumably why you have needed to worry about QoS. Buy bigger pipes. :-) ...
