8 Scenario 2: Business user with TOS marking.
Introduction
In this chapter we will explain on how IP QoS for a business user can be configured.
In our example we will use the following configuration:
On the LAN three groups of devices "Gold", "Silver" and "Bronze".
Some Expedited Forwarding applications.
The CPE is remotely managed.
The CPE is the trusted edge device and performs the TOS/DiffServ marking for
the Gold, Silver, Bronze and Remote Management traffic.
Expected result
In this case the desired behavior is that the EF traffic has strict priority over all the
other traffic, but with an overflow to a lower priority queue in case the EF traffic
exceeds 50 percentage of the available upstream bandwidth.
Weigthed fair queuing is used between the Remote Management, the Gold and the
Silver traffic; this traffic is AF marked by the CPE.
The Bronze traffic is BE marked by the CPE and gets lower priority than all other
traffic.
