RUT240 Load Balancing

Table of Contents

Summary #

Load balancing lets users create policies and rules that divide traffic between different interfaces. This chapter is an Overview of the Load Balancing function in RUT routers.

The information in this page is updated in accordance with the RUT2XX_R_00.01.12 firmware version.

Policies #

The Policies section contains Load Balancing policies. One default policy named Balanced is already in place. You can edit this default policy or create a new custom policy.

To configure a Policy, click the Edit button located next to it, after which you will be redirected to the Configuration window.

As you can see from the image above, the configuration is very simple. You can assign ratio values to WAN interfaces. The ratio values represent a percentage of load that will go through an interface. For example, in the default configuration 3 parts of traffic will go through the Mobile interface and 2 parts will go through the Wired interface, which means roughly 60% (3/5) of data will be transferred through Mobile, 40% (2/5) through Wired. If the ratios would be different, say Mobile: 5, Wired: 10, then 33% (5/15) of data would be transferred through Mobile, and 66% (10/15) would go through Wired.

Rules #

The Rules section contains Load Balancing rules. One default rule named default_rule is already in place. You can edit this default rule or create a new custom rule.
