So, what is Touchstone?

Touchstone is an offering from VoerEir as a tool for NFVI benchmarking, certification and validation. Touchstone is a Test Suite manager, which comes with multitudes of automated test cases and tools out of the box for testing a cloud environment’s performance, functionality, robustness and stability.

Touchstone offers facilities to benchmark multiple cloud environments spanning multiple data centers. It provides support for benchmarking the environments using an advanced test engine developed by VoerEir, and many popular open source test engines like OpenStack Rally, OPNFV Yardstick and Google PerfkitBenchmarker among many others. Touchstone provides a wide array of features for environment benchmarking, report management, and Enhanced Platform Aware (EPA) test suites. Touchstone is a touchstone in cloud environment benchmarking, certification and validation.

Our thinking behind Touchstone

The following statement serves as a base for NFV strategy for identifying performance responsibilities between NFV and VNF vendors;
“Verify that your NFV-Infrastructure fulfills its performance KPIs, and it becomes VNF vendors’ responsibility to fulfill theirs."

NFVI Certification

VoerEir is a member of Linux Foundation and Linux foundation Networking. We have representatives in the latter's "Compliance and Verification Comity" (CVC). VoerEir’s prime focus is to work within OPNFV, for which our head in India Arif Kahn has an ambassador role. Within OPNFV we contribute to OVP (OPNFV Verification Platform) and Yardstick, their working group for performance measurement. This work gives us a unique position to do vendor independent NFVI Certifications as a service.

VoerEir’s test system, Touchstone, is delivered with thousands of pre-integrated Test Cases. This includes Test Suites for both OpenStack and OPNFV Certification. These are used for our OpenSource community certification service.

Touchstone also comes with pre-configured Test Suites to measure around 200 NFVI-KPIs. These test suites have been used for validating quite a few operators NFVI, coming from several different vendors. Based on this experience VoerEir has compiled an Industry Benchmark.

In Touchstone, VoerEir has also configured a Test Suites for Robustness and Stability to secure that an NFVI is ready for serving as a telecom Platform in operation.

VoerEir offers a service which Certifies, Benchmarks and Validates for operation readiness, an operator's NFVI. This is done by connecting the NFVI to a local or remote installed Touchstone system and execute all these Test Suites. Included in the Service is also an investigation around found weaknesses. E.g., Deep analysis of test reports, Test Cases can be re-run with slightly changed parameters to better understand route cause to Bottlenecks, or, e.g., stochastically occurring disturbances influencing test results. The result from the Service is a ~50 page report, showing all test results, pointing at possible root causes, and explaining potential impact for different kinds of VNFs

Education & Consulting


VoerEir has during the last years been giving courses to several Tier1 operators. These courses have typically been tailored after customers’ needs and wishes. Based on who the audients were and how much time the customer wanted to invest.
We have been giving two kinds of course; Touchstone training including hands-on exercises, and around technology issues that impact NFV strategies.

Based on this experience we have created two course-packages;

  • "NFVI technologies What you need to know."
  • “Testing with Touchstone”
Both can be done as 1 – 3 days workshops, with topics according to the document the links below points at.

Consultancy Services

VoerEir provides technical consulting based on a very long and deep understanding of the technical challenges of NFV transformation. T he cornerstone of technical consulting is in-depth knowledge of the interworking between VNF application and NFVI infrastructures. Understanding the issues around this interworking is essential to secure a successful NFV transformation, and many examples exist where lack of understanding has led to severe delays for operators’ NFV transformation programs. Our experience in Technical consulting includes; writing RFQ for NFVI procurement, evaluation of RFQ answers both for NFVIs and VNFs, Cloud testing and troubleshooting.


VoerEir has developed the V8LS methodology and we provide transformational consulting based on this methodology. The cornerstone in the method is a clear definition of the demarcation point between the VNF applications and the NFVI cloud infrastructure. A clear demarcation point is critical for successful NFV transformation and impacts the way VNF applications and NFVI cloud infrastructure are designed, procured, deployed, tested, validated and operated. VoerEir has a unique industry understanding how the technical considerations impact the overall transformation.
