We want to take a moment to highlight some of those contributions (and the people) that are making a substantial difference across our amazing communities.

ONF Developer Relations (DevRel)

  • ONF is working on a community recognition plan for ONF Connect. We will soon be asking the communities for recognition recommendations.
  • The Devrel team is focused on re-doing the on-ramp documentation on both the web site and the project wiki sites. This will bring a much more consistent and informative experience to people new to the ONF communities.
  • ONF and DT co-organized the Open Networking Community Meeting in Berlin (agenda, slides). Thanks to Manuel Paul from DT for organizing and hosting.

Certification Brigade

  • CORD TST approved Fabric Switch Test Verification Document.
  • OLT Certification Program - The Brigade kick-started the OLT certification program by coming up with an “Introduction, Scope and more” document with an intention to capture the general guidelines, scope, the if and buts related to the program to keep all interested members in sync. This is a live document and all interested members are welcome to add new items and make comments.


  • Developed initial version of Comac-in-a-Box which can be run on any kind of machines including VM without SR-IOV support for easy dev and testing. Also started to work on End-to-End emulation by integrating OpenAirInterface eNB and UE into OMEC for the minimum functional test.
  • Implemented a COMAC release Jenkins file to automatically deploy/configure COMAC PODs. The Jenkins file includes several steps from ETCD installation steps to XOS deployment steps. It can be used for COMAC CI/CD.
  • Created Grafana dashboards for COMAC Monitoring service for single k8s cluster scenarios.
  • Integrated the latest XOS Helm charts for the first COMAC release. XOS has definitions of each COMAC service (e.g., EPC-CP, EPC-UP, CDN-Local, CDN-Remote). Also, XOS visualizes COMAC service chains according to the service definitions.
  • Started to define the COMAC user plane network by using SR-IOV CNI and work on refactoring ‘mcord-services’ Helm charts for the first release. Also, fixed a minor bug in ‘mcord-setup’ Helm-charts to configure SR-IOV device type.


  • Model registry has been added to allow a complete set of models supported by a device to be registered. This facilitates thorough data validation using the YANG models.
  • Implicit rollback capability was added for the NB gNMI to make sure that configurations made to multiple devices on the network are all committed or that none-of them are.
  • Administrative and diagnostic commands have been enhanced to use the same style interface as Kubernetes, Helm, etc. This supports shell auto-completion and automated usage generation.
  • Integration testing framework (onit) was created to facilitate writing integration tests natively in Go and allowing them to be executed within the context of a Kubernetes installation. On developer machines, this can be done via kind or minikube.
  • CI job has been added to start running the integration tests after each merge commit.
  • Build scheme has been enhanced to be more efficient with time and computing resources when generating docker images for the onos-config system.
  • Stratum/mininet docker image has been incorporated into the integration testing scheme.

CORD Platform

  • Released cordctl v1.1.0 with improvements to formatting and error reporting

OIMT (Open Information Modeling & Tooling)

  • Followed up on the action items from the May face-to-face joint OIMT & OTCC Beijing meeting.
  • Held an OTCC and OIMT joint “virtual face-to-face” for one day to continue detailed technical discussion on TAPI 3.0 issues.
  • Started planning for the September CA meeting. Confirmed on the date (September 9-13) and host/venue (Cisco campus).
  • Worked on the Profile & Template model addressing the general problem and the specific narrow case to be supported for the OCTT Wireless Transport (WT) project. (6/13 OIMT
  • Worked on aligning the TAPI equipment and the WT equipment models. Discussing the use of class vs datatype.
  • Worked on the update to the state model (TR-512.3) addressing entity state in the complex supporting/dependent relationship, and considering multi-level abstraction in TAPI, including alternate abstraction. 
  • On the UML to YANG mapping, discussed and agreed on the rule of mapping UML navigable association-ends to YANG. Discussed the use of the “when” statement, which is needed for TAPI 2.2 and WT.


  • Fixed the wrong MSISDN number show up in S11 interface.
  • Added PTI (procedure transaction identity) feature for S1AP messages.
  • Ashok from Intel shared the OpenMME performance design documents. The open mme improvement design will be based on this.
  • OpenMME design model was reviewed.
  • OpenMME code will need to be re-structured for better software engineering - Code constants, extensibility.


  • ONOS now supports Java 11, i.e. building and running with JDK 11
  • The internal ONOS OSGI implementation was upgraded to Apache Karaf 4.2.6
  • ONOS builds were upgraded to use bazel 0.27
  • Nikolai Merinov (Inango-Systems) fixed data packet deserialization when Ethernet frames have the payload less than 46 bytes
  • The image size of the ONOS Docker was reduced to simplify building and reduce download times
  • Anton Lin (ONF intern) created an application registry that allows users to register their own applications. The portal has a table GUI and REST API and is backed by a GitHub repository.
  • Arnav Jain (ONF intern) enhanced the application subsystem to allow listing applications that have been registered and are compatible with the running version of ONOS. Additional enhancements are being made to the ONOS CLI and REST API to allow easy installation of applications from the registry.

OTCC (Open Transport Config & Control)
