Aether 

  • Started to support OAI CU/DU and USRP B210 devices with Aether-in-a-Box. It is running over band 7 (FDD). Started to make them work over CBRS band (TDD).
  • Started work on Aether@Home to also work on Linux platform.
  • Work on 5G Core has started. This involves writing helm charts and docker files for 5G core.

Ambassador Program

  • ONF Ambassador LATAM team conducted two webinars “Working with ONF to Transform Mobile & Broadband Networks”:
  • ONF is once again very happy to welcome new ambassadors. In October we had four new Ambassadors join our team:
    • Amit K Borkar – Network consultant in Bengaluru (Karnataka), India, working with service providers and system integrators helping them to transform operations and drive efficiencies during their digital transformation journeys. Amit started his SDN journey in 2016 and is involved in various projects related to SDN, NFV, and SD WAN. His major expertise lies in setting up production-grade SDN-NFV Lab, Solution Engineering, and Research & Development around SDN NFV Domain.
    • Hugo Alberto Nava – Electronics Engineer in Colombia with over 17 years in the telecommunications industry. Expertise includes fixed and mobile Tier 1 CSPs and manufacturers, network design, rollout, and operations. Active promoter of Open Networking adoption and industry collaboration within Open Networking Foundation, Telecom Infra Project, and Linux Foundation Networking and TM Forum.
    • Dr. Akram Hakiri – Associate professor of Electrical Engineering and Computer Science at the University of Carthage, and a research scientist at SYSCOM Labs’ ENIT, both in Tunisia. Dr. Hakiri has been providing talks and presentations at different international universities in the USA, India, France, Tunisia, and Romania and is serving as a peer reviewer for dozens of top-rated journals and in the technical program committee for multiple international conferences. His current research focuses on developing novel solutions to emerging challenges in network virtualization, software defined networking, QoS, resource management in wireless networks, and DRE middleware running over data networks and embedded system interconnects.
    • Slavko Pandurov – Open network consultant in Serbia with over 15 years of experience in the domain of integrations, IP solutions, and telecommunications. Slavko is helping companies modernize their networks, drive operational efficiencies, and re-build supply chains in accordance with open networking principles. His skills and experience include market analysis and strategic planning, start up projects, ICT infrastructure projects, sales strategy creation/training/execution, and channel and partnership development.

COMAC+OMEC

  • Learned the default testing tool inside free5gc, and tried to separate the RAN and UE emulator. Later on, the RAN and UE emulator will be used with container based free5gc setup.
  • PCRF is introduced in the OMEC. 
  • SPGWC now supports Gx interface (PCRF for initial authorization).
  • Work on dedicated bearers in OMEC is in the testing phase.

Developer Relations

OIMT

  • Explored modeling of IP and SD WAN by using the Core model.
  • Planned virtual face-to-face OIMT meetings on November 30 and  December 2-4.
  • Received three ITU-T SG15 liaison statements. (1) Consent of Amendment 1 to G.807 “Optical media network architecture” and Amendment 1 to G.872 “OTN architecture”; (2) Consent of new Recommendations on MTN, namely G.8310 “Architecture of the metro transport network” and G.8312 “Interface for a metro transport network”; and (3) Coordination of information and data modeling and invitation to participate in a series of multi-SDO virtual meetings.
  • Overview of G.807, G.872, G.8310, & G.8312 was provided to OIME by ITU-T experts. No implications were identified for the TR-512 Core model in supporting the new transport functionalities, but more examples would be beneficial. TAPI will need more augmentations for supporting MTN.

ONOS/µONOS

  • ONOS 2.5 Feature Freeze is coming up next Friday, November 13th; bug-scrub meeting scheduled for the week of November 9th
  • ONOS code-base scrubbed of a number of defunct applications and extensions, therefore slimming it down
  • µONOS SD-RAN project is starting to move beyond prototype phases and aims for trial-ready release by Q2 2021

OTCC

  • TAPI testing in the OIF Interop Demo has been going on through the month with heavy use of TR-547 as a testing reference.  Thanks again to Arturo Mayoral (Telefonica) as the main editor.  Testing will continue through the first week of November and then results will be gathered.
  • TAPI subteam held a virtual face-to-face meeting on October 19-21 and October 28th, led by Andrea Mazzini (Nokia) as the co-team leader, with help from Nigel Davis (Ciena).

P4

SEBA/VOLTHA

  • SEBA RD 2.0 Release – TLT approved it; ready for membership review for 60 days
  • Focus on scale with enhanced flow replication that sped up the whole system, resulting in needed improvements in the VOLTHA core, OF agent and ONOS AAA, DHCP and OLT apps. Improvements include flow and barrier reply handling, thread offloading, lock optimization, introduction of option 82 for the circuit Id to handle offloading to host and other bug fixes. Thanks to Matteo Scandolo, Girish Gowdra, Saurav Das, Andrea Campanella and the special guest Pier Luigi Ventre. 
  • Open Onu Adapter Go successful dataplane test with 1T8GEM DT workflow and several error scenarios implementation, along with flow deletion and tests to match these scenarios Thanks to the Adtran Team, in particular Michael Pagenkopf, Holger Hildebrandt and Torsten Thieme and ONF with Andrea Campanella. 
  • Change to BAL 3.4.7.5 for the openolt agent, thanks to the BAL brigade. 
  • Implementation of the DMI interface on top of BBSIM to simulate device management. Thanks to Amit Ghosh from Radisys and the DMI brigade. 

Stratum

  • Max Pudelko and Brian O’Connor (ONF) added support for a new protobuf-based P4 device config format for the Stratum Barefoot target.
  • Brian O’Connor, Max Pudelko, Yi Tseng (ONF), and Jimmy Ou (Edgecore) revised and improved the process for building the Stratum Barefoot target (i.e. BF SDE, Debian package, and Docker image).
  • David Gengenbach (USI) provided a fix for the Stratum Mininet Docker container.

Trellis

  • TOST now runs in 2×2 topology with INT integrated and data plane high availability.
    • Control plane high availability will come in Q4.
  • Pier Luigi Ventre (ONF) has made several contributions:
    • Added the support for MODIFY operation on SIMPLE nexthop when using fabric-tna, fabric-tofino and basic pipelines.
    • Extracted pipeline-dependent code from T3 and created the first implementation of the traceable behaviors.
    • Improved the onos-diagnostics-k8s integration in TOST.
    • Fixed several bugs for the TOST build pipelines.
