Bandwidth
Control When:
With this option selected, the Bandwidth Control will take effect when the
bandwidth usage reaches the specified value.
¾
Default Limit
Limited Bandwidth:
Default Limit applies only for users that are not constrained by Bandwidth
Control Rules. These users share certain bandwidth with upper limit
configured here. Value 0 means all the remained bandwidth is available to
use.

Interface Bandwidth
Interface:
Displays the current enabled WAN port(s). The Total bandwidth is equal to
the sum of bandwidth of the enabled WAN ports.
Upstream
Bandwidth:
Displays the bandwidth of each WAN port for transmitting data. The
Upstream Bandwidth of WAN port can be configured on
WAN
page.
Downstream
Bandwidth:
Displays the bandwidth of each WAN port for receiving data. The
Downstream Bandwidth of WAN port can be configured on
WAN
page.
Note:
The Upstream/Downstream Bandwidth of WAN port you set must not be more than the bandwidth
provided by ISP. Otherwise the Traffic Control will be invalid.
If there are data flowing into the Router from interface A and out from interface B while the
downstream bandwidth of A is different from the upstream bandwidth of B, then the smaller one
should be considered as the effective bandwidth, and vise versa.

Bandwidth Control Rule
Direction:
Select the data stream direction for the entry. The direction of arrowhead
indicates the data stream direction WAN-ALL means all WAN ports
through which the data flow might pass. Individual WAN port cannot be
selected after WAN-ALL rules are added.
Group:
Select the group to define the controlled users.
Mode:
Individual: The bandwidth of each user equals to the current bandwidth
of this entry.
Shared: The total bandwidth of all controlled IP addresses equals to the
current bandwidth of this entry.
Guaranteed
Bandwidth (Up):
Specify the Guaranteed Upstream Bandwidth for this entry.
Limited Bandwidth
(Up):
Specify the Limited Upstream Bandwidth for this entry.
Guaranteed
Bandwidth (Down):
Specify the Guaranteed Downstream Bandwidth for this entry.
Limited Bandwidth
(Down):
Specify the Limited Downstream Bandwidth for this entry.
Effective Time:
Specify the time for the entry to take effect.
Description:
Give a description for the entry.
Status:
Activate or inactivate the entry.

List of Rules
You can view the information of the entries and edit them by the Action buttons.
The first entry in Figure 4-28 indicates: The users within group “sales” share the bandwidth and the
Downstream/Upstream Guaranteed Bandwidth is 5000kbps, while the Downstream/Upstream Limited
bandwidth is 10000kbps. This entry takes effect at 8 a.m. to 10 p.m. from Monday to Friday.

Note:
The premise for single rule taking effect is that the bandwidth of the interface for this rule is
sufficient and not used up.
It is impossible to satisfy all the guaranteed bandwidth if the total guaranteed bandwidth specified
by all Bandwidth Control rules for certain interface exceeds the physical bandwidth of this
interface.
4.5.3 Session Limit
The amount of TCP and UDP sessions supported by the Router is finite. If there are some local hosts
transmitting too many TCP and UDP sessions to the public network, the communication quality of the
other local hosts will be affected, thus it is necessary to limit the sessions of those hosts.
