[c-nsp] Queueing strategy

[r.sahney]

Hi ,

What is the average utilization, and what kind of traffic is going on these 
links. eg - voice , data etc.

You will first need to identify the traffic and accordingly prioritize the 
traffic, if u send me your config and requirement offline i will guide you 
how to go about it.

Also it would be wise to read the cisco site for understanding of basic Qos 
and queuing techniques.
