Yes, there is a separate buffer pool for each bandwidth channel.
This is so flow control can be handled completely separately for
each channel. Clients from one channel cannot affect clients in
another.

Do clients belonging to different bandwidth channels receive
the same packets? Or in order to make the slow clients catch up
quickly, does DCMS send fewer packets to the slow clients? If
DCMS send fewer packets to the slow clients, what is the ratio
for high, medium, and slow channels?

DCMS send fewer packets to the slow clients, what is the ratio
for high, medium, and slow channels?
DCMS sends fewer packets to clients in the lower bandwidth
pool. For example, if you were to share a clock, a high bandwidth
client may see a change in the second hand every one to two
seconds, whereas a low bandwidth client may only see the second
hand change every five seconds. Another example would be if
you share a PowerPoint slide presentation that includes
animation. Participants in the web conference will only see the
final slide, but not the animation.

The maximum rate at which DCMS will send data on each
bandwidth channel is (in bytes per second):
bandwidth channel is (in bytes per second):
•
Low channel bandwidth = 2000 (i.e., 16kbps)
•
Medium channel bandwidth = 5000 (i.e., 40kbps)
•
High channel bandwidth = 200000 (i.e., 3200kbps —
effectively unlimited for a LAN connection)
This does not, however constitute a constant ratio, as usually the
send-rate will not max out these bandwidths.

What are the TCP ports that need to be opened in order to host
a web conference?
a web conference?
If a socket connection needs to be established, TCP port 1627
should be opened for WebShare and TCP port 1503 should be
opened for a T.120 application such as NetMeeting.
