Class-map || High Router utilization

[praveen.apr30]

Hi Team , 

Good day!!!

I have one very basic question regarding the class- map.

We have implemented QOS by defining some set of classes with the percentage of bandwidth in each class.

now a days i could see lot of routers in the organization i work for having issues with the high utilization .

we heard that the ISP has changed their configuration of QOS.

is it like both the customer and ISP should have the same  kind of configuration to have my router work properly ?

if one class is being highly utilized, will it affect the entire router performance ?

Thanks 

Praveen
