[c-nsp] QoS concerns

[Mihai Todor]

Hello,

I have some issues related to QoS I hope you might help to shed some light
upon:

1. Is there any maximum bandwidth allocation percentage for the LLQ deployed
in conjuction with CBWFQ/MDRR so as to enssure that other non-priority
traffic classes are not starved when PQ utilizes the maximum bandwith. The
plaforms details are:
- XR 12406, SIP 601, SPA-10X1GE-V2 running IOS XR 3.8.0
- 7609-S, SIP 600, SPA-5X1GE-V2 running IOS 122-33.SRB5 Advanced IP Services

2. Is there any possibility that a 7206VXR performace is impacted by
deploying traffic marking policies based on input interface? The plaform
configuration is:
- 7206VXR, NPE-G1, PA-2FE-TX running IOS 124-15.T9 Advanced IP Services

3. Has anyone deployed with satisfying results the classification of voice
traffic within a normal class (not priority)? The benefit would be the
possibility of borrowing bandwith from the other classes when available.

Many thanks for any of your comments!
