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
