Chapter 10 QoS 10.3.3 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 Figure 36) in a DiffServ 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. Figure 36 DiffServ Network 10.4 Port-based Priority You can configure the Switch to assign a IEEE 802.1p priority to packets based on the ingress (incoming) port of the packet.

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
Figure
36
) in a DiffServ 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.

Port-based Priority
You can configure the Switch to assign a IEEE 802.1p priority to packets based on
the ingress (incoming) port of the packet.
