Full QoS scenario 1: tiered services for a single customer
Bronze traffic is also allowed to burst up to the full egress bandwidth of the uplink port, but when congestion occurs, will be throttled back in favour of Gold traffic, and will share the remaining bandwidth with Silver traffic in a Weighted Round Robin fashion. The ISP makes no guarantees at all with regard to delivery of Bronze traffic across their network; it will be delivered on a
Identify the types of traffic
The different categories of traffic will be identified by the DSCP values in the packets' headers. It is up to the customer to mark the packets with the appropriate DSCP values.
The DSCP values belonging to the different traffic categories are:
Gold 40
Silver 30
Bronze 0
The classifiers to match these DSCP values are:
create classifier=1 ipds=0
create classifier=2 ipds=30
create classifier=3 ipds=40
XPut the different categories of trafffic into different queues
There are 3 flow groups created, and the appropriate classifiers are added to each flow group:
create qos flowgroup=1 create qos flowgroup=2 create qos flowgroup=3
add qos flowgroup=1 classifier=1 add qos flowgroup=2 classifier=2 add qos flowgroup=3 classifier=3
Then three traffic classes are created, each containing one flow group:
create qos trafficclass=1 create qos trafficclass=2 create qos trafficclass=3
add qos trafficclass=1 flowgroup=1 add qos trafficclass=2 flowgroup=2 add qos trafficclass=3 flowgroup=3
create qos policy=1
add qos policy=1 traffic=1,2,3 set qos port=1 policy=1
This way, each category of traffic is associated with a different traffic class.
