rate. Priority data is bounded so that low priority data is not starved. If low
priority clients are starved, they generate retries that may exacerbate
congestion during periods of peak usage.
⇒ Select Traffic Shaping
o Enable Traffic Shaping --


Check this box to enable the Traffic
Shaper.
 Note; With Traffic Shaping disabled the registered VoIP
device’s to the systems ALG will still have their layer 3 packets
marked as TOS 0xb8 or DIFFServ AF46. Data traffic by default will
be re-written to 0x00 (See Enable TOS Byte Stripping)
o WAN Downstream Bandwidth --

 Enter the total actual
downstream bandwidth that applies to your WAN connection. Value is
entered in Kbps e.g. 1024 = 1 Mbps.
o WAN Upstream Bandwidth --

 Enter the total actual upstream
bandwidth the applies to your WAN connection. Value is entered in
Kbps e.g. 1024 = 1 Mbps.
o Enable Priority IP Address --

 If the user wants a device in the
network to be high priority, its IP address can be added manually to
the list of high priority devices. Use care when entering IP addresses in
this list. Devices that consume all the bandwidth may cause media
quality problems.
☞ Enter an individual IP or range e.g: 192.168.1.10-150 to delete
the entry highlight it and delete.
 Note: Devices that use the VoIP ALG function (phones, video
stations, etc.) are already marked as high priority and do not need
to be in this list. All data from IP addresses in this list has the same
priority as voice data. Poorly behaved data may cause voice quality
problems. Use with caution!
o Enable TOS Byte Stripping --

 Enable TOS Byte Stripping option:
By default, this option is checked. For all RTP traffic (voice and video)
we mark the TOS byte as "High Priority", and strip (set to 0) the TOS
byte for all other traffic. Un-checking this option means that the TOS
byte will NOT be stripped from non-RTP traffic, but will remain
unchanged.
o Enable Call Admission Control --

 Check this box to enable the
Call Admission Control.
