• WRR Weighted Round Robin utilizes a process scheduling function that prioritizes
traffic according to the pre-defined ‘Weight’ parameter of a traffic’s class. This level of
prioritizing provides more flexibility in distributing bandwidth between traffic types, by
defining additional classes within a parent class.
Schedule By default, the class will always be active. However, you can configure
scheduler rules in order to define time segments during which the class may be active. To
learn how to configure scheduler rules, refer to the ‘Defining Scheduler Rules’ section of
the iPECS SBG-1000 Administrator Manual.
5.3.4.3 Setting an Incoming Traffic Policy
When shaping the traffic for a device, you must also determine a policy for incoming traffic. In the
‘Edit Device Traffic Shaping’ screen (see Figure 5.60), configure the following fields in the ‘Rx
Traffic Policing’ section:
Rx Bandwidth This parameter limits the device’s bandwidth reception rate. In this example, the
purpose is to limit the bandwidth that the WAN device can receive from the ISP.
Queue Policy Similar to Tx traffic, Rx traffic queueing can be based on a traffic class or on strict
priority (unless unlimited bandwidth is selected). By default, however, the queue policy is set to
Policer, which is a relatively simple method of bandwidth control. With the policer option, you can
dedicate a portion of the bandwidth to a certain traffic type. This portion will always remain
available to its traffic type, even when not in use. This is a simpler method, as priority is not used
at all.
When selecting a class-based queue policy, you must define an Rx Traffic Policy Class, which is
identical to defining a Tx Traffic Shaping Class, described earlier. However if you select the policer
as your queue policy, defining a policing class is even simpler, as it lacks the priority setup.
To define an Rx traffic policy class, perform the following:
1. In the ‘Edit Device Traffic Shaping’ screen (see Figure 5.60), click the ‘New Entry’ link in the
‘Rx Traffic Policing’ section. The ‘Add Policing Class’ screen appears.
Figure 5.65 Add Policing Class
2. Name the new class and click ‘OK’ to save the settings, e.g. Class B.
3. Back in the ‘Edit Device Traffic Shaping’ screen, click the class name to edit the traffic class.
Alternatively, click its action icon. The ‘Edit Policing Class’ screen appears.
