[c-nsp] Question about LLQ

[Ibrahim Abo Zaid]

Hello

I'm bit confused about bandwidth assigned for priority queue when using LLQ
, if the assigned amount of BW for PQ is high percentage from interface
bandwidth say 50%
and the offered priority traffic rate don't consume that much
my question is about unused amount for BW can be assigned to other
non-priority classes

i read couple of papers in Cisco and some said YES the total amount of
unused BW is proportional shared between classes according to the configured
bandwidth
and some considers the concept of "total available bandwidth" which is the
maximum amount of interface bandwidth can be used by non-priority classes
and this amount = total interface bw - [ Reserved BW ( Def is 25% of
interface bw) + priority classes BW]

I need to know if both are correct ? is it depends on interface types ?

Thanks
