An optional feature of the BIG-IP® system is the systems ability to load balance and persist requests that applications send to servers running Diameter services.
You implement Diameter load balancing by creating various local traffic objects in an administrative partition. The remainder of this chapter describes this process.
Important: To implement Diameter load balancing, you must have a user account with the Administrator, Resource Administrator, or Manager user role assigned to the account. You must also have access to the administrative partition in which the local traffic objects will reside when you create them. For information on creating partitions, as well as managing partitions and partition access, see Chapter 23, Configuring Administrative Partitions to Control User Access.
For more detailed, background information on configuring Diameter-related local traffic objects, see the Configuration Guide for BIG-IP® Local Traffic ManagerTM.
The first task in configuring Diameter load balancing on the BIG-IP system is to create a custom Diameter profile. A Diameter profile defines the way that you want the BIG-IP system to manage application traffic that is targeted to servers running the Diameter service.
After you create the custom Diameter profile, you create a Diameter monitor and a load balancing pool. Then, you create a virtual server and assign the custom profile and the pool to that virtual server.
1.
On the Main tab of the navigation pane, expand Local Traffic, and click Profiles.
3.
Click the Create button.
4.
In the Name box, type a unique name for the profile, such as my_diameter_profile.
6.
Click Finished.
Once you have created a Diameter profile, you can create a custom Diameter monitor. The purpose of the Diameter monitor is to monitor the health of all servers running the Diameter service.
1.
On the Main tab of the navigation pane, expand Local Traffic, and click Monitors.
This displays a list of all pre-configured monitors.
2.
Click the Create button.
3.
In the Name box, type a unique name for the monitor, such as my_diameter_monitor.
4.
From the Type list, select Diameter.
6.
Click Finished.
The next step in a basic Diameter load balancing configuration is to define a load balancing pool that contains Diameter servers as its members.
1.
2.
In the upper-right corner of the screen, click Create.
The New Pool screen opens.
3.
In the Name box, type a name for the pool, such as my_diameter_pool.
4.
For the Health Monitors setting, use the Move button to move the custom Diameter monitor you created in the previous section from the Available box to the Active box.
5.
In the Resources area of the screen, use the New Members setting to add the pool members.
6.
Click Finished.
The final task in configuring Diameter load balancing is to define a virtual server that references the custom Diameter profile and Diameter pool that you created in previous tasks.
1.
On the Main tab of the navigation pane, expand Local Traffic, and click Virtual Servers.
2.
Click the Create button.
This displays the settings for a Standard type of virtual server.
Type: Choose virtual server type Host.
Address: Type an IP address for the virtual server.
Service Port:: Type the number for the Diameter service port.
Select the custom Diameter profile that you created previously, such as my_diameter_profile.
4.
Click Finished.
After you have created the virtual server, you can test the configuration by attempting to pass Diameter traffic through the virtual server.
