Avnu Certification

Benefits of Certification

With the increasing demands on networks, it is necessary for networks to support time-sensitive applications while being secure, manageable, and reliable. Avnu Alliance is playing a critical role in meeting these demands with a focus and expertise on Time Sensitive Networking (TSN). Within this, is the need for “Best in Class” interoperable products. Avnu Alliance has built a robust Certification program to help our members successfully contribute to those demands. Members have access to development tools and resources to help our members through the Certification process to develop standard conformant and interoperable products based on TSN capabilities. Our Certification program offers many benefits, including, but not limited to:

  • Reliability in how their products will perform using Time Sensitive Networking and AVB technologies
  • Faster Time to Market
  • Interoperable with other Avnu Certified Products
  • Reduction in tech support costs

Designed and maintained by experienced certification management professionals, Avnu’s Certification program provides members with real-time visibility into the testing process and the ability to track device progress and timelines. 

Avnu members can submit products for testing, view results, respond to nonconformance issues, and manage the public listing of newly Certified products. All certification and testing documents are easily managed in a single, centralized location. Intelligent workflows feed data and visibility back to Avnu’s Certification Work Group to track the number of products in certification at each lab, enabling Avnu to scale the capabilities as needed to support testing demand.  The testing program will continue to evolve; additional certification test plans will become available through global facilities as the TSN ecosystem grows. For more information see the steps to certification below. 

“Certification of any standards-based technology is important for three reasons. First, it ensures that what is being produced adheres to the standards the certification is built on. Second, it ensures that equipment will work together. And third, certification means multiple vendors are in the market, which positively impacts the price to the end user,” says Gary Stuebing, Avnu Alliance Chairman.

Steps for Avnu Certification:

  1. Become an Avnu Alliance member, and pay the applicable annual membership fee.
  2. (Optional) Purchase Avnu’s Express Test Tool to help in the development of your product prior to going to test lab.
  3. Applicant registers product with Avnu Alliance using the Certification Management System.
  4. Upon approval of the above and confirmation of member’s status, Avnu’s Technical Programs Manager will inform the Applicant and the Recognized Test Facility (RTF) of Applicant’s choice of the product assigned TestID (TID), test versions, CRSL version, and other information.
  5. Remit payment of Avnu Product Registration fee to Avnu Admin.
  6. RTF executes required conformance test cases ensuring tests are executed correctly. After testing is complete, RTF issues preliminary test report(s) for review by the Applicant.
  7. If the device fails, the Applicant is notified of the failure and reason. The Applicant and RTF collaborate to determine whether the Product needs to be fixed or a Waiver should be submitted.  The Applicant will work with the RTF and Avnu Technical Programs Manager as outlined in the Certification Process Flow to fix the product and retest, or have the failure waived.
  8. If the device passes, the RTF generates a Certification report for review by the Applicant and Avnu Technical Programs Manager. If the Avnu Technical Programs Manager approves of the passing Certification report, certification of conformance is granted to the Product and the CertificationID (CID) is issued.

Avnu Plugfests

Avnu Alliance members benefit from participating in pre-certification plugfests that offer a unique hands-on opportunity for engineers to test connectivity and interoperability. Plugfests are useful for cross-pollinating best practices between developers from different companies and bootstrapping test plans when common implementation mistakes are seen. Plugfests can also help members spot product issues early on in the process, analyze device behavior and make changes to improve interoperability before entering certification testing.

Avnu Express Testing Suite & Tool

Avnu Alliance has introduced a test tool to streamline the certification process for vendors. Avnu’s low-cost validation test tool, the Avnu Express Test Tool, allows vendors to internally verify device conformance prior to submission for certification testing, providing valuable insights into the product that can be used to optimize product development – increasing the probability of certification success and saving manufacturers time, resources, and money. Members can use the test tool, which bundles test control and test engine software along with a set of hardware equipment, to verify the performance of end devices using Certified modules. Members can also integrate the test tool into their regression test bench for internal automated regression testing and can easily add their own test scripts for their own product development as well as for debugging and testing.

Avnu members can purchase floating licenses that allow teams across geographic locations to work using the same tool and the Avnu Express Test Tool will be automatically updated as new test plans become available. 

For those interested in getting access to the Avnu Express Test Tool, please contact our Technical Program Manager at

Avnu Recognized Test Facilities

Avnu has Certification testing at new Registered Test Facilities (RTF) around the world. These well-recognized, globally dispersed test labs offer lower shipping times, competitive pricing models, and streamline the process for members seeking to certify products and make communications between testing sites and vendors seamless. These additional test sites and locations give Avnu Alliance greater ability to scale testing capacity to meet demand, while also allowing device manufacturers to enter products into testing with less lead time prior to release. 

Avnu Alliance Certification Testing must be conducted at an Avnu-approved Recognized Test Facility.  These test facilities have been selected, evaluated, and audited by Avnu and found to meet the requirements to conduct Avnu Certification Testing in accordance with Avnu Policies defined by the Avnu Certification Work Group. The scope of testing for each Recognized Test Facility is captured in the table below.
