Configuring Local Traffic Limiting

Local Traffic Limiting allows traffic limiting rules to be configured for each site, when this is necessary. These rules take the enterprise organization, user subnets and applications implemented between these different entities into account. They are used by Application Control.

These rules are defined for outgoing (LTL Ingress) or incoming (LTL Egress) traffic on the selected site.

LTLs are used to limit the bandwidth used by the different networks of the departments, services (user subnets) or applications according to specific criteria taking the following constraints into account:

source subnet,
remote subnet,
applications,
TOS/CP values.

Traffic Limiting is given in a tree structure, each LTL is characterized by:

a name
filters to define the rules for classifying the traffic that corresponds to the LTL
a limit on the bandwidth that can be used by the class

Note: LTL rules are enabled if and only if Application Control is activated on the Appliance.


1 In the Application provisioning Toolbar, select Local Traffic Limiting.

The Local Traffic Limiting Tree window is displayed.

This window contains a Local Traffic Limiting tree structure per Appliance.

2 To create a new policy, select the Appliance and the direction (ingress or egress). Then click the New icon to display the following window:

This window contains the following parameters:

Name: Name of the LTL policy,

Local Traffic Limiting

Maximum bandwidth (kbps): to specify the limit bandwidth for a LTL. If the value 0 is specified, all the traffic is dropped.
Limited: to enable or disable the limiting rule.

Filters

You may filter the traffic related to a LTL. The available options are:

Source user subnet: to filter the traffic by Source User subnet. Select it from a drop-down list that corresponds to the "User subnets" directory,
Destination user subnet: to filter the traffic by Destination User subnet. Select it from a drop-down list that corresponds to the "User subnets" directory,
Application: to filter the traffic by application. Select it from a drop-down list that corresponds to the "Applications" dictionary,
TOS/CP: to filter the traffic by TOS value. Select this value from a drop-down list that corresponds to the "TOS/CP" dictionary.
