The DCCA Server Node Test Case
If you purchased the DCCA Server Emulation feature, you can use the DCCA Server Node test case as a virtual DCCA server in a test session. The virtual server provides Credit Control services for an SUT.
Using a Virtual DCCA Server
Add the DCCA Server Node test case to a test session and configure the SUT to direct DCCA traffic to the virtual server's IP address. The diagram below shows a virtual server used in conjunction with a GGSN Nodal test. One virtual server can service more than one SUT as long as the virtual server's message attribute configuration will produce response messages that are valid for the SUTs.
The test case can also emulate two servers, one primary and one secondary, for failover testing as shown in the diagram, and can generate messages as though they were routed by a Diameter proxy, eliminating the need for physical proxy servers.

IMPORTANT: As with all co-resident test cases, when a DCCA Server Node test case shares the same test server as another test case the maximum activation rate and capacity of the nodal test case is reduced.
You can avoid these restrictions by running the DCCA Server Node test case on another test server as shown in the diagram. |
With each test case, you define:
-
The virtual server's IP address
-
The number of mobile subscriber accounts that can be supported
-
The mandatory and optional Diameter Base and Credit Control Application AVPs, and the maximum rate at which sessions can be deactivated.
-
The credit authorization mode: session-based or direct-debiting
-
A starting account balance and the amount and type of credit units that will be granted for each request in session-based mode.
-
Optional re-authentication frequency, failover support, and failure simulation.
