Automated Testing of Network Functions

Optimize Automated Testing with our Professional ServicesKeysight’s professional services organization (PSO) is the resource customers need to get the most value from Ixia products. If you are short on test personnel, time, or budget, our team is ready with a test plan, the tools, and the experts to run the tests and explain the results.

With our broad range of professional services, you have expertise at your fingertips to:

• Assess and optimize network performance, validate compliance, and harden security

• Gain visibility into network applications and services to accelerate troubleshooting and enhance monitoring performance

• Harden mission-critical networks against attack and train personnel to recognize and eradicate vulnerabilities

• Improve performance, security, and application delivery of cloud, data center, and network services


Automate Faster with Customized Framework All major network equipment manufacturers rely on Ixia to help keep them on the cutting edge. With development cycles increasingly compressed, network vendors need the right test and test automation framework in place to meet tough demands. The last thing you need is another proprietary automation solution.

In a continuous-integration/-testing/-delivery (CI/CT/CD) DevOps environment, the construction and configuration of the testbed needs to be completely orchestrated and automated. Whether you are working in a physical lab, virtual lab, or some hybrid environment that includes physical devices, private clouds, and public clouds, Ixia’s automation helps you maximize your investment and minimize test cycles.

Ixia’s team of professionals have been at the forefront in designing and implementing the industry’s widest array of test methodologies and automation frameworks. Our experienced Solution Architects, Professional Services, and Scripting Services teams will help you craft the ideal automation solution that addresses your specific goals. We create entire solutions from a variety of proven products, or simply accelerate the integration of our test tools into your custom automation framework.

The following architecture enables a faster and more comprehensive automation solution by using a REST API interface into an automation framework.

The Customer’s Automation Layer provides test and results management, as well as interface into network functions. Ixia’s Validation Layer provides the test tools and a repository for test modules.

The repository’s API enables clients a more flexible mechanism to communicate with all of our test tools; as well as a library of test modules. The test cases associated with these test modules are called by the Automation Layer with test parameters and pass/fail criteria. The test cases executed with Ixia’s test tools (IxNetwork, IxLoad, BreakingPoint, and LoadCore™ 5G Core Testing) enable functional, negative, and performance testing. These test modules will operate with either Keysight’s virtual or physical test tools.

What is a Test Module?

A Test Module is a collection of test cases to perform validation of a specific network function, or combination of network functions. Under each module, tests are grouped into different tests suites based on the underlying test tools used or the objectives of the test functions. All test cases can be operated individually or sequentially based on the API call to our repository. Test cases are based on the experience of Ixia performing testing for Service Providers, Network Equipment Manufactures (NEMs), and Enterprise customers.

This brochure summarizes the Test Modules that are being released by the Keysight’s Professional Services team to help customers achieve a faster return on investment (ROI) in their performance of testing. Each module summary contains a sample test network architecture followed by a list of the individual test cases in the module. Every test case also includes a short description of the goal of the respective test case.

This data is a snippet of information from the overall test plan that is supplied with each test module. Contact [email protected] for further details and ordering information associated with the test modules.

Session Border Controller (SBC)

Test Network ArchitectureThe following diagram illustrates the topologies these test cases simulate:

• In the first case, the originating and terminating SIP users are in one network, while the other network hosts the SIP registrar and proxy.

• In the second case, two originating and terminating SIP users are in two individual networks. No SIP registration or proxy exists in this scenario.

Figure 6: Session Border Controller Test Network Architecture

Testing Description

The SBC test module emulates the endpoint(s) in Network 1 on one side of the SBC, and the endpoint(s) in Network 2 on the other side. The test cases in the module cover a wide range of aspects related to the VoIP traffic, including basic VoLTE registration, VoLTE to VoLTE calls, maximum call setup rate and concurrent calls, as well as voice quality and performance.
