26.1.2 DiffServ Network Example

The following figure depicts a DiffServ network consisting of a group of directly connected
DiffServ-compliant network devices. The boundary node (A in
network classifies (marks with a DSCP value) the incoming packets into different traffic flows
(Platinum, Gold, Silver, Bronze) based on the configured marking rules. A network
administrator can then apply various traffic policies to the traffic flows. An example traffic
policy, is to give higher drop precedence to one traffic flow over others. In our example,
packets in the Bronze traffic flow are more likely to be dropped when congestion occurs than
the packets in the Platinum traffic flow as they move across the DiffServ network.
