### **Name**

Name of the instance

### **Modus**

The [method](#load-balancing-algorithm) or algorithm used to distribute network traffic among servers.

### **Origin**

Origin server IP address

### **Instance**

The specific instance for which load balancing shall be enabled.

### **Name of Load Balancing Instance**

Defines the name for the load balancing instance.

***

### **Origin IP-Address**

IP of the origin; used for traffic forwarding.

***

### **Origin Timeouts**

Timeouts for the origin server. Slower backend servers may need a higher timeout time.

### **Load Balancing Algorithm**

Load balancing distributes network traffic across different servers. Different load balancer methods distribute traffic according to different criteria.

* *Round Robin*: Origin servers are used continuously one after the other.
* *Weighted Round Robin*: You can define weight points for your origin IPs. IPs with a higher weight will be used more.
* *Least Used*: The next request is assigned to the server with the least number of active connections.
* *Sticky-IP*: Weight-based load balancing; a client IP address will always forwarded to the same origin server.

***

### **Configure Weighted Load Balancing**

Weight ratio. You can assign points from 0 – 1000. Origin servers with a higher weight will be used more.

| Load Balancing method        | Configuration                                  | Description                                                                                         |

| Random weighted distribution | rand:ip1/weight1,ip2/weight2\[,ipN/ weightedN] | You can define weight points for your origin IPs. IPs with a higher weight will be used more often. |
| Roundrobin                   | rr:ip1,ip2\[,ipN]                              | Origin servers are used continuously, one after the other.                                          |
| Least used                   | lu:ip1,ip2\[,ipN]                              | Next request is assigned to the server with the least number of active connections.                 |
| Sticky-IP                    | stickyip:ip1/weight1\[,ipN/\[weightN]]         | Weight-based load balancing; a client IP address will always forwarded to the same origin server.   |
