[c-ubr] docsis 1.1 qos question

[James Galliford]

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.
