Creating A Qos Set - Avaya P550R User Manual

Creating a QoS Set

Avaya P550R/P580/P880/P882 Multiservice Switch ATM Uplink Module User Guide, Version 2.0
There are four different Service Categories that apply to QoS Sets.
They are:
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.
CBR (Constant Bit Rate) - Is used for connections that
depend on precise clocking to ensure undistorted delivery. It
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 the traffic still needs a guaranteed QoS.
This service category is intended for non-real-time
applications with variable traffic, guaranteed delivery, but not
dependent on time.
* Note: When attempting to establish non-UBR traffic class
connections on the ATM Uplink module, the ATM
switch to which the ATM Uplink module is connected
may reject the initial connection request due to lack of
resources. The ATM Uplink module retries the
connection as UBR. Although this provides maximum
connectivity, it may not provide the expected QoS.
To create a QoS Set:
1. Select Modules & Ports > Configuration from the Web
Agent. The Module Information dialog box opens
(Figure 18).
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 19).
3. Click Additional Configuration. The ATM Configuration
dialog box opens (Figure 20).
4. Click QoS Settings. The QoS Domains dialog box opens
(Figure 26).
