Creating a QoS Class Set
There are four different QoS class sets:
■
UBR (Unspecified Bit Rate) - Allows any amount of data up
to a specified maximum to be sent across the network, but
there are no guarantees in terms of delivery, file transfer,
Ethernet connectivity, cell loss rate, or delay.
to a specified maximum to be sent across the network, but
there are no guarantees in terms of delivery, file transfer,
Ethernet connectivity, cell loss rate, or delay.
■
CBR (Constant Bit Rate) - Is used for connections that
depend on precise clocking to ensure undistorted delivery. I
is recommended that constant bandwidth is always reserved.

■
rtVBR (real time Variable Bit Rate) - Is used for connections
in which there is a fixed timing relationship between
samples. This is a service category intended for time
dependent, real-time applications (voice and video) with
variable bandwidth.

■
nrtVBR (non-real Time Variable Bit Rate) - Is used for
connections in which there is no fixed timing relationship
between samples, but that still need a guaranteed QoS. This
service category is intended for non-real-time applications
with variable traffic, guaranteed delivery, but not dependen
on time.

To create a QoS class set:
1. Select Modules & Ports > Configuration from the Web
Agent. The Module Information dialog box opens
(Figure 3-1).
(Figure 3-1).
2. Click ATM in the Type column of the ATM Uplink module
you want to create the QoS class set for. The ATM Module
Information dialog box opens (Figure 3-2).
Information dialog box opens (Figure 3-2).
3. Click Additional Configuration. The ATM Configuration
dialog box opens (Figure 3-3).
4. Click QoS Settings. The QoS Domains dialog box opens
5. Click Manage QoS Sets in the QoS Column for the QoS set
you want to manage. The QoS Sets for QoS Domain <#>
dialog box opens (Figure 3-10).
