docsis 1.1 qos question

Hello:

My company is deploying voice services via packetcable and I have a
question about QoS. Our telephony partner will not be using DQoS to
dynamically create the call service flows. Because of this, I am
manually creating two dedicated service flows for the voice traffic in
the docsis1.1 config file.

I am using the UGS scheduling type on the upstream. My question is
this: By using the UGS scheduling type, am I reserving that bandwidth
so that only that modem and that service flow can ever use that
bandwidth? Currently, the UGS service flow takes approximately 98k of
bandwidth. If I provision 50 UGS service flows, will I have effectively
reserved all my bandwidth and not have any left over for the BE traffic?

Thanks for any help!

Hi Matt,

I believe that by using the UGS type of scheduler that the bandwidth
is only reserved for when the service flows are actually active and
working. Otherwise, it's business as usual and the Best Effort
traffic will be able to use that bandwidth.
