TRAFFIC SHAPING CONFIGURATION
Traffic shaping is an optional software feature in the IQ 710 that enables the user to manage bandwidth
allocation by setting the guaranteed bandwidth and maximum bandwidth. Traffic shaping can be applied
on a PVC or application level. When applied at either level, the user may select an application or PVC
from the discovered list and enter the guaranteed and maximum bandwidths. The discovered list is auto-
matically generated by the IQ 710 and consists of any PVCs detected and any application for which the
IQ 710 has detected traffic flow through the unit. Upon power up, the list will be blank and will populate
automatically as data is transmitted through the unit. An application or PVC will remain on the list even if
that PVC is deleted or that application traffic is removed from the circuit. The list will be cleared if the unit
is power cycled.
The range for the guaranteed and maximum bandwidths is dependent on the network configuration port
speed. The ranges for the three sites are as follows:
Huntsville IQ 710
• T1 (24 channels at 64K)
• Guaranteed bandwidth range
• Maximum bandwidth range
Atlanta IQ 710
• T1 (4 channels at 64K)
• Guaranteed bandwidth range
• Maximum bandwidth range
Birmingham IQ 710
• T1 (2 channels at 64K)
• Guaranteed bandwidth range
• Maximum bandwidth range
By programming a guaranteed bandwidth, that bandwidth will be reserved for the application or PVC for
which it was programmed. However, when the PVC or application is not using the bandwidth, it will be
dynamically reassigned to other applications. Maximum bandwidth is the maximum amount of bandwidth
the user wants reserved for a particular PVC or application.
In this example, traffic shaping is especially important in a delay-sensitive application such as packet
voice.
