Ambassador Program

  • Have you considered representing ONF at various industry events? Do you like presenting to and mingling with like-minded people to advance the mission of ONF? If yes, why not join the ONF Ambassador Program. Check out the details here. We support our ambassadors participating in industry events representing ONF, check out the budget request details here. For a list of recent events by our ambassadors, click here.
  • Most recently, we welcomed three new ambassadors:
    • Ricardo Girnis Tombi works at Universidade São Judas e Instituto Mauá de Tecnologia as a professor. He is based in Brazil and speaks Portuguese, Spanish, and English. He has recently been focusing on optical networks.
    • Scott Swail works at Lumentum as the VP of business development. He is based in the US. He has recently been focusing on ODTN, ONOS, and TIP projects.
    • Huai-Wen Hsu works at Edgecore Networks as an Engineer. He is based in Taiwan and speaks Mandarin and English. He has recently been focusing on ONOS applications and various PoCs.
  • In January we completed our annual Ambassador check-in to capture and celebrate the highlights from each ambassador in 2019 and to hear about all their plans for 2020.

COMAC+OMEC

  • Nokia shipped two ocp servers to ONF. Mobile team started to set up SPGWU and CU of the enodeb to check whether OMEC can work with the ocp server or not. If yes, ONF will take those servers to the OCP conference to give a show for OMEC.
  • Added an apn feature to handle when phones do not send out any apn during the attach procedure. This feature can also handle, when the phones send out unknown apn.
  • We are preparing to attend MWC, purchase spectrum, electricity, set down the location of the terminal of the satellite, etc.
  • Automated license check tool Fossa with jenkins, team started with openmme repo and multiple branches, then will automate more repos under OMEC.
  • SGWC does not need to know the MME address while starting. This address configuration dependency is removed.
  • MME does not need to know the SGW address in the configuration. Now even if SGW/PGW hostname is provided in the configuration then MME resolves the hostname to ip address.
  • Subscriber monitoring framework is available. This framework provides a REST api which can be used to pull the subscribers from the MME.
  • Fixed the critical bug that packets from UPF dropped by driver for spoofing.
  • Finished setting up one more Aether control plane in Azure for MWC demo.
  • Finished setting up MWC Edge pod and connected it to Aether control planes running in Google Cloud and Azure via VPN. Also verified serving two networks, CBRS and Band7, in the single Edge.
  • Started writing Edge site admin guide.
  • Started deploying Intel Edge.

Developer Relations

  • In November we started our infrastructure renewal project where we are consolidating various tools like Crowd, Wiki, Jira, etc. into single ONF instances. We have now completed the Crowd consolidation project and are starting to work on Wiki consolidation.
  • SEBA Surge is in full swing and we are working with the community participants to energize the SEBA community and improve productivity. Several previously inactive SEBA Surge team members have started to contribute to the project. This is what our community is all about!
  • Save the date - ONF SEBA/VOLTHA Surge Team Meetup will take place April 27-30 in Berlin, Germany, hosted by DT. This is a technical event targeted to all SEBA/VOLTHA team members, including developers.
  • Save the date - ONF Community Meetup 2020 - Europe will take place June 2-3 in the Hague, Netherlands, hosted by KPN. This is an architecture and business focused event.
