Select this option to disable Bandwidth Control.

Select this option to enable Bandwidth Control all the time.

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.

-58-

¾

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.

-60-

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.
