OpenFlow conformance certification OpenFlow switch conformance certification assures product compliance with the OpenFlow specification Issued by ONF and applicable to all OpenFlow enabled networking hardware and software switches Successfully certified products can use Open Flow Conformant logo on products and collaterals. Certified products will also be listed on the ONF website Switch conformance certification program is available from the ONF for OpenFlow 1.0 specification Switch conformance certification program for OpenFlow 1.3 specification is currently in pilot phase 2014 Criterion Networks.

Open Flow 1.0 conformance program Open Flow Conformance for Full, Layer 2 or Layer 3 profile depending on which of the 12 match fields are implemented by the switch vendor All mandatory test scenarios for a given profile needs to pass for a device to be considered conformant https://www.opennetworking.org/sdn-resources/onfspecifications/openflow-conformance https://www.opennetworking.org/images/stories/downloads/sdn -resources/onf-specifications/openflow-test/conformance-testspec-openflow-1.0.1.pdf Program recently expanded to accommodate non-onf members 2014 Criterion Networks.

Open Flow 1.3 conformance program Open Flow 1.3 conformance test cases for a base profile Core Open Flow 1.3 test cases (single table only) Details on additional profiles to be announced in future Pilot phase until Q3 2015 Four ONF labs, test equipment vendors, NEMS participate in the pilot Vendors who are ONF members can participate in the pilot program and get their products certified at the end of the period Significant publicity is planned by the ONF for NEMs who take their products through the pilot program for 1.3 conformance testing Only ONF members can participate until program is Generally Available 2014 Criterion Networks.

Work Flow Vendor Develops Product Identify preferred tool(s) for in-house testing or alternately do pre-test with the lab Vendor Contacts Test Lab Submit completed conformance application form to test lab Sign agreement with test lab Schedule test Submit completed equipment and test information form to test lab Deliver Equipment Product Passes Vendor authorizes results for submission to ONF Lab submits results to ONF for review ONF awards conformance certificate to the vendor Product Fails Vendor may submit for retest Vendor may dispute results with Lab and/or advisory board 2014 Criterion Networks.

Test labs The ONF has chosen to allow 3 rd party testing labs perform official conformance testing. Authorized test labs sign a testing service agreement with the ONF The ONF will maintain a list of authorized test labs along with contact information. Device manufacturers will contract directly with authorized test labs to perform official conformance testing. The vendor and lab will be responsible for scheduling and agreeing when to submit test results to the ONF The lab will provide results to the ONF in a standard report format as defined by the test specification along with a recommendation for a Conformance Logo 2014 Criterion Networks.

CNLabs OF conformance test program A mutual NDA is signed along with a testing agreement Vendor submits the required forms and provides the product with candidate image to the lab Its quite common for test cycles to be iterative and a product might require multiple rounds of testing before actually passing the conformance test. Hence CNLabs offers three different models for the product vendors to engage with the lab (summarized in next slide) The vendor selects the program which best meets their needs On successful completion of a conformance test, CNLabs will share test results with vendor and ONF along with recommendation for certification to the ONF The ONF does an internal review and reverts back to the vendor with their decision to award conformance (typically 2 weeks) * Conformance logos are applicable for each product family 2014 Criterion Networks.

CNLabs OF conformance test program Option1 Option 2 Option 3 One test cycle Three test cycles Multiple test cycles Vendor submits DUT with candidate image for conformance testing to lab Vendor submits DUT with candidate image for conformance testing to lab Vendor submits DUT with candidate image for conformance testing to lab If test passes, lab submits result to ONF to seek certification. If test fails results are sent to vendor Vendor has to submit new application for re-test efforts CNLabs will do up to 2 cycles of pre-testing on the candidate image before initiating final test cycle If test passes, lab submits result to ONF to seek certification. If test fails results are sent to vendor Vendor has to submit new application for subsequent re-test efforts CNLabs will do up to 2 cycles of pretesting on the candidate image before initiating final test cycle Additional pre-test efforts would be invoiced weekly (up to max 12 weeks) When test passes, lab submits test results to ONF (after vendor approval) 2014 Criterion Networks. All Rights Reserved 11
Confidentiality All test results are kept confidential during the conformance test program, however to obtain a certification, the test results will need to be released to ONF along with the recommendation from the lab for product conformance. Vendor will need to provide consent for the same as part of the testing agreement To protect the confidentiality of other customers, vendors are typically not allowed in the lab during official testing. However during the test period, they can chose to monitor the test progress with prior request. The lab will take additional precautions as needed to protect customer interest. 2014 Criterion Networks. All Rights Reserved 12
