16.5.1 Priority Levels
Traffic with a higher priority gets through faster while traffic with a lower priority is dropped if the
network is congested.
The following describes the priorities that you can apply to traffic that the NBG-417N forwards out
through an interface.
• High - Typically used for voice traffic or video that is especially sensitive to jitter (jitter is the
variations in delay).
• Low - This is typically used for all other traffic that are not time-sensitive.
Specific Port This displays the port/s assigned to the service.
You can also specify the port/s to services to which you want to allocate
bandwidth. Choose either Both, TCP or UDP in the drop-down menu and enter
the port or range of ports in the provided boxes.
Note: If you are entering a specific port and not a range of ports, you can either
leave the second port field blank or enter the same port number again.
Bandwidth
Allocation
Use this table to allocate specific amounts of bandwidth to specific protocols on
an IP or IP range.
# This is the number of an individual bandwidth management rule.
Enable Select this check box to have the NBG-417N apply this bandwidth management
rule.
LAN IP Range This displays the range of IP addresses for which the bandwidth management
rule applies.
Direction These read-only labels represent uplink or downlink traffic.
To LAN applies bandwidth management to traffic from WAN to LAN/WLAN (i.e.,
downlink).
To WAN applies bandwidth management to traffic from LAN/WLAN to WAN (i.e.,
uplink).
Both applies bandwidth management to traffic that the NBG-417N forwards to
both the LAN and the WAN.
Port Range This displays the range of ports for which the bandwidth management rule
applies.
Policy This displays either Max (maximum) or Min (minimum) and refers to the
maximum or minimum bandwidth allowed for the rule in kilobits per second in
the field below.
Rate This is the maximum or minimum bandwidth allowed (refer to the field above)
for the rule in bits per second.
