Hi,

last week I had a NetMeeting session, image quality was poor and sound was bad. 
With MSN Messenger,
the sound was ok.

>From the same station to another one in the lab, all was OK.

We have a 100 Mbps optical link to the Internet, and the other guy was on cable
modem.  We have GbE
backbone here, with a 100 Mbps feed to the station.

So I started to learn about tc, I defined a class to reserve some bandwidth
(500Kbps) for this
station, and plan to test again in a few hours.

Is it enough to reserve bandwidth?  I read that latency could be an issue. Can I
use tc to reduce
latency?

Thanks.

Reserving bandwidth would normally be a smaller part of the problem
with Netmeeting, but in your case, you've got plenty of bandwidth.

Latency is a larger issue, and while you can use 'tc' to define QoS
and try to control latency outbound from your link, you have no
control over what happens once the Netmeeting packets hit the
Internet, especially when they hit the cable network, which might more
than likely be where most of the latency gets picked up.
