What You Need To Know
You can limit an application’s uplink or downlink bandwidth. This limit keeps the
traffic from using up too much of the out-going interface’s bandwidth. This way
you can make sure there is bandwidth for other applications. Use the following
guidelines:
•
The sum of the bandwidth allotments that apply to the WAN interface (LAN to
WAN, WLAN to WAN) must be less than or equal to the
Uplink
value that you
configure in the
Bandwidth Management
General
screen.
•
The sum of the bandwidth allotments that apply to the LAN port (WAN to LAN,
WAN to WLAN) must be less than or equal to the
Downlink
value that you
configure in the
Bandwidth Management
General
screen.
15.4
General Configuration
Use this screen to enable bandwidth management and assign uplink/downlink
limits. You can use either one of the following types:
•
Priority Queue
. Enable bandwidth management to give uplink traffic that
matches a bandwidth rule priority over traffic that does not match a bandwidth
rule. (This type does not apply to downlink traffic.)
•
Bandwidth Allocation
. Enabling bandwidth management also allows you to
control the maximum or minimum amounts of bandwidth that can be used by
traffic that matches a bandwidth rule.
Note: You cannot apply both bandwidth management types at the same time.

Use this screen to configure bandwidth managements rule for specific protocols on
an IP or IP range.
Note: This screen contains the

Though both tables are described in this section, you can only apply the rules in
one table. Fill out the table of the

Management.
Uplink
Type or select the total amount of bandwidth (from 64 Kbps to 30
Mbps) that you want to dedicate to uplink traffic.
If you type the amount of bandwidth, the selection automatically
becomes
User Defined

field automatically displays the value in Kbps.
This is traffic from LAN/WLAN to WAN.

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
NBG4604 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.
