XFAST: Fully Automated Software Testing

Network operators must continuously improve their infrastructure: On the one hand, rapid technological development requires the implementation of ever new services and applications with an increasing complexity of the functions to be mapped. On the other hand, the systems must be regularly updated to the latest and most secure versions of the various operating software – also to protect the network.

The smooth operation of the productive network infrastructure is essential for the availability of the services provided via it and thus also for the reputation of the network operator. However, reliable testing and qualification before implementing changes in the production network requires resources with the appropriate know-how, time and a well-equipped laboratory environment.

Challenges & Risks –
Qualification of changes in the productive network



  • Time expenditure
    The preparation of a test environment alone is very time-consuming for creating a realistic scenario. In most cases, numerous steps – such as installing the correct operating system or setting up the devices’ configurations – have to be performed manually. Problems caused by faulty software or errors in your test setup lead to unforeseeable delays and repetition.

  • Resources & Know-how
    Realistic testing, software qualification and network components require an appropriately equipped laboratory environment. Also, trained employees with in-depth technical know-how in the functioning of the systems and expertise in the execution of the tests are required – highly qualified employees who are bound by the duration of the qualification.

  • Security
    If operating systems are only brought up to date in longer-term cycles, this not only inhibits innovation but also reduces security – because security updates must also be extensively tested before they are deployed. In addition, if End-of-Service (EoS) releases continue to be used, manufacturer support is no longer guaranteed in the event of a fault.

Xantaro is specialised on two essential factors for high-performance networks of carriers and service providers: innovative, customised technology solutions, first-class service and support over the entire lifecycle.

To meet the ever shorter innovation cycles and testing times, Xantaro offers with XFAST a service that significantly reduces testing efforts, increases the quality of the results and reduces risks when introducing new operating systems into the productive network environment to a minimum.

Reliable network operation and reduced effort through test automation

Based on the latest technology, XFAST qualifies new operating systems (e.g., Junos OS from Juniper Networks) fully automatically, independent of vendor and technology. The service is continually being expanded with self-developed software components and is linked to load generators. The definition of realistic test setups and routines ensures that reproducible and precise results are achieved.



Depending on complexity and scope, these tests are completed within a few minutes or hours; considerable time saving compared to the manual test execution. In this way, network operators receive a concrete statement on the planned update in the productive network in the shortest possible time.

  • Planning
    Together with the customer, the test setup is first defined, and all relevant protocols and services are modelled and integrated into XFAST. If necessary, load patterns are specified to ensure that the test setup is as close to the customer’s productive network as possible.

  • Execution
    The test scenarios are fully automated in the XT3Lab – the Xantaro Technology, Testing & Training Lab – or in the customer’s laboratory environment.

  • Results
    Immediately after completion, the test results are documented and made available in the form of detailed PDF reports. As part of our service, our experts also provide support for error analysis and communication with the vendor if required.


XFAST – advantages at a glance

  • customer-specific and realistic test scenarios
  • time saving due to automated execution
  • no long-term commitment of internal resources
  • Risk minimisation through precise and reproducible results
  • Error analysis and communication with the vendor
  • Savings opportunities through calculable costs
