  • Huge efforts were made in VOLTHA to achieve persistent storage of data on ETCD with improvements across the stack, core, adapters and agent, thanks especially to Ciena and ONF. 
  • Multi-uni support was introduced in VOLTHA and the ONOS applications, providing the capability to provision subscribers on all the UNIs of an ONU, thanks to NETSIA and ONF.
  • ONU software upgrade achieved tenfold time improvement and new download/activate/commit APIs thanks to ADTRAN, Radisys, and ONF. 
  • Testing was extended with 10 TT tests, Performance Measurements, and new ONU software upgrade tests thanks to NETSIA, ADTRAN, and ONF. 
  • VOLTHA moved to use ONOS 2.5, thus getting up to par with TOST and other ONF projects, joining efforts towards bug fixes and enhancements in the same ONOS release, thanks to ONF.


  • The P4 Ecosystem was recently launched which features products, projects, and services that utilize P4. If you are a P4 user and would like to have your solution featured in the P4 Ecosystem, please check out the web page and submit your information. If your solution is already featured and you have updates, please fill in the submission form as well and we will update your info.


  • Max Pudelko (ONF) contributed several fixes and features for Stratum Tofino (stratum_bfrt), including initial QoS capabilities and support of the board support package (BSP) for the Edgecore Wedge100BF platform. The BSP provides better support for optical transceivers, gearboxes, and retimers.
  • Brian O’Connor and Max Pudelko (ONF) released Stratum 21.06, which includes many enhancements and fixes for Tofino: two new SDE revisions, deflect on drop, and initial experimental support for QoS. This is also the first release to include BSP support.


  • ONOS has now the capability to annotate meters and flow objectives allowing for additional information and more complex workflows, thanks to Andrea Campanella (ONF).
  • Daniele Moro (ONF) added the capability to program in one shot the action profile in PI.
  • Miguel Borges de Freitas (Altice Labs) improved the OpenFlowMeterProvider by making the reconciliation configurable.
  • Implemented the capability to parse the last-changed GNMI leaf during the periodic reconciliation and during port operational status changes (ONF).
  • Improved the GeneralDeviceProvider reconciliation (ONF) by preventing the cancellation of the periodic checkup task and by adding the discovery of the device ports.
  • Andrea Campanella (ONF) improved the FOBJ manager by invalidating the pipeliner cache when the driver for a device changes.


  • Held virtual meetings on June 1-4, covering the models of Aggregate, Control, Environmental and physical dimension sensors, Spec pattern, Security, Assignment state, Interface vs logical interface point (LTP), and OIMT model design principles. Details are available at https://wiki.opennetworking.org/display/OIMT/2021+Jun+01-04+%3A+OIMT+Virtual+Face-to-Face.
  • Continued discussion on the Control model with respect to the security and negotiation consideration.
