[c-nsp] Cisco ASR 1002-X PPPoE Subscriber QoS policies

[eyeballi77]

Hi folks,

I have to setup a QoS policy to maximise the limited bandwidth on the cross
connects to our broadband backhaul provider.

To date I have used per session policies but I am not sure that this will
account for the scenario where all subscriber sessions request more
bandwidth that the cross-connect is provisioned for.  So I need to ensure
that in this given scenario that the business critical application/service
for each session are guaranteed a min. amount of bandwidth while dropping
all other non-essential traffic.

I have read that without BRR the allocation of remaining bandwidth may not
be equally apportioned, but before that I need to ensure that the business
critical app gets it .min bandwidth.  That said is it a case of using a
priority queue to provide the necessary guarantee in the above scenario?

I have some reading to do, but would be grateful for any advice / input...

Many thanks advance..
Neil
