DiffServ: Performance Impacts and AF-Classes

Hello,

I´m starting some DiffServ-Testing to implement

QoS in a Multivendor Environment. I would like to start with only 3 AF-classes and only one DSCP per Class for data purposes only.

To mark the pakets I had some pbs understanding the burst params of CAR, therefore I´m now using policy-maps (without policer and shaper).

At this time I´ve no idea on the impact on Router

performance and throughput using policy-maps on E1 and E3 links and on LAN-Interfaces for input-marking.

Whats also unclear for me is the relation

between the dscp-based WRED IOS values for the AF classes (in some examples on CCO AFx3 has higher drop denotiators and higher Min-Thresholds as AFx1) and the intentions in the RFC for the AF classes (AFx1 is better/more reliable service than AFx3)

Any contact welcome,

best regards,

Alfred
