The Datalink Service Load Balancing (DSLB), also known as Uplinks Load Balancing, enables the creation of highly available and scalable WAN uplinks using layer 3 protocol.

The DSLB farm profile allows users to create route-based farms where the backends are uplink routers or gateways. This profile typically facilitates sharing multiple uplink WAN router accesses, utilizing the load balancer as an uplink channel multiplexer (one input and several router line outputs). Consequently, DSLB farms can serve as highly available communication links and can be used for bandwidth scaling, thereby increasing the bandwidth between the router’s backend links.

The diagram below illustrates an example of load balancing several uplinks with different weights.

DSLB Farms List #

Consider using the following action buttons for each selected farm.

Create Farm. Creates a new farm managed by the DSLB farm profile.
Restart. Reboots a farm service in the DSLB farm profile.
Stop. Stops the selected farm’s services.
Start. Starts the selected farm’s services.
Delete. Stops the services and deletes the farm’s configuration.

The actions will be executed in batches across all the selected farms (using the multichoice selector checkbox).

DSLB Farms Table #

Farm listings and properties of each farm. The fields displayed per farm are described below.

Name. A descriptive name for the farm. This value will be unique across all the virtual services you create.
Virtual IP. The IP address managing incoming local traffic. This virtual IP can be moved to another node in the cluster and can act as the LAN default gateway.
Interface. The network interface managing incoming traffic and distributing requests to the WAN networks.
Status. The current status of the farm, indicated by the available status indicators.

• Green. Indicates UP. The farm is running, and all backends are operational.
• Red. Indicates DOWN. The farm is stopped.
• Yellow. Indicates RESTART NEEDED. Recent changes require a farm restart to take effect.
• Black. Indicates CRITICAL. The farm is running, but no backend is available, or they are in maintenance mode.
• Blue. Indicates PROBLEM. The farm is running, but at least one backend is down.
• Orange. Indicates MAINTENANCE. The farm is running, but at least one backend is in maintenance mode.

Actions. These are the available actions/icons for each farm in the table:

• Edit. Modify the basic and advanced options for a virtual service or farm, create new services, and apply those changes to the backends.
• Restart. Reboots the farm.
• Stop. Available only if the farm is running. All traffic managed by this farm will be dropped once the command is executed.
• Start. Available only if the farm is stopped. The service will bind to the configured IP and interface, allowing the farm to handle the traffic.
• Delete. Stops the farm, deletes all configuration files, and releases the IP for use by another farm.

Next step, create a DLSB farm.
