Aether 

  • We investigated the free5gc 5G SA open source project. We set up the recent two releases, stage 2 and stage 3. Free5gc itself has basic test cases, like registration and deregistration, paging, handover. Moving forward, Martin from NG4T agreed to work with us to set up the ng40 5G testing environment to test free5gc, and provide us with a license.
  • Started to integrate new CBRS eNB from Baicell.
  • Finished to initial Aether deployment step on Argela site; Argela edge has CDN use-case with Aether SPGW-U.
  • Aether Edge on Laptop supports PFCP to communicate with the Aether control plane.
  • Prometheus integration done with SPGW, MME, HSS. 
  • Verified NG40 tests on Aether production.

Ambassador Program

  • We are pleased to introduce two new ONF Ambassadors who recently joined our program:
    • Masagung Nugroho – a telecommunication professional who has experiences in IP/Routing, Transport SDN, open networking and mobile technology evolution. Given more than 12 years’ experience in the telecommunication environment, he always catches-up with the new technology evolution in the industry. Masagung is currently working as an APAC Senior IP Systems Engineer in Infinera. He is responsible for the Infinera’s IP/SDN portfolio along with the customer engagement in the APAC region. Prior to this role, he experienced engineering, business development and network design for service provider environments both post-sales and pre-sales for many major vendors in the market, including Nokia and Juniper. He is an ambassador for ONF in APAC with areas of interest in ONOS, CORD and SDN/NFV. Holding a bachelor’s degree from Telkom University, Indonesia, majoring Telecommunication Engineering, Masagung Nugroho is also a petrol head, tennis player, family guy and father to a very handsome boy.
    • Virgilio Fiorese (aka Vico) – in his own words: I’ve been in the Telco industry since 1994, and my whole professional life has been about connecting people and things. Prior to joining Radisys, I spent the previous 11 years at Ericsson where I had the opportunity to develop new relationships into the Rural America ISPs and the WISP industry. Today I’m working to help the Rural ISPs adopt SEBA/VOLTHA as part of Radisys’ SD-PON commercial solution – Connect Open Broadband. Our solution is fully disaggregated, allowing customers to have horizontal and vertical freedom to mix and match different hardware and software vendors. I support Open OMCI and I promote the increase of open ONUs, the increase of white boxes OLT hardware suppliers, and the increase of SDN solutions that can manage multiple FTTH access solutions allowing both brown and greenfield deployments. As part of my participation in ONF, I will be promoting SD-RAN, and it will be a pleasure to apply my background from both 3GPP and Open RAN domains to help the ecosystem. Follow me on Twitter at @vfiorese or let’s connect on LinkedIn at www.linkedin.com/in/telecomguru/.

COMAC+OMEC

  • NSA support is complete at MME.
  • Dedicated bearer support at MME, SPGW  is in progress.

Developer Relations

ODTN

  • Patch is uploaded and undergoing review with extension and bug fix for the OpenROADM driver thanks to Roberto Morro (TIM).
  • Scale tests with high number of ROADMS (250~) got started by Robert Morro (TIM. Initial results are promising although further debugging is needed due to some ports not getting discovered, discussion is ongoing with Alessio Giorgetti, Ramon Casellas and Andrea Campanella. 
  • Patch is uploaded and undergoing review on TAPI driver for full TAPI topology exposure with gerrit patch thanks to Giuseppe Iaffaldano (Intento Project). 

OIMT

  • Collaborative discussion occurred with ITU-T Study Group 15 Question 14 on the modeling of Optical Amplifier (OA). There was some tentative agreement that the amplifier should be made from elements of a Spec that causes augment where the augment can be for either the Logical Termination Point (LTP) or Forwarding Construct (FC0. The amplifier and its monitors should be Spec building blocks (like LegoTM). The vendor is then able to construct from the building blocks what reflects their realization.
  • Received incoming liaison statement from MEF informing the publication of draft standards MEF 84 on Network Slicing and soliciting comments from ONF. Discussion occurred to prepare ONF feedback by early September.
  • Works continued to develop the security model for auditing and the Spec occurrence model

ONOS/µONOS

  • µONOS RIC is being refactored to split E2 termination into a separate micro-service.
  • µONOS onos-config subsystem is being enhanced with features required for it to serve as the Aether configuration subsystem.
  • µONOS SD-RAN team has started participating in O-RAN WG3 meetings and is starting talks with O-RAN SC on possible collaborations.
  • It has been decided that, when released, ONOS 2.5 will be designated as an LTS; it will be used as the base for the Aether/Pronto project.
  • ONOS TST decided that a number of defunct contributions involving support of legacy protocols (e.g. ISIS, OSPF, PCEP, BGP-LS) and several stalled projects (e.g. TE topology, L3VPN, YMS) will be removed from the code-base to reduce the liabilities (build times, maintenance overhead, and security risks). The first wave of such pruning is currently under review in Gerrit.

OTCC

P4

  • The P4 Language Design Working Group organized a brainstorming session in August to inform the future evolution of the language.
  • CFP is open for the 3rd P4 Workshop in Europe on December 2, 2020 in Barcelona, Spain. Don’t miss this opportunity to share your experience and knowledge and collaborate with peers. To learn more about the event and submit your CFP, please visit the P4 website.

SEBA/VOLTHA

  • Introduced dynamic log collection through EFK and call tracing through logs (log correlation). A huge thanks to Infosys, in particular to Divya Desai and Girish Kumar.  Please check TST recording.
  • Stricter Code quality checks and bug finding tools have been put in place for repos thanks to Andrey Pozolotin (Reply).
  • Initial scale tests for the openonu written in GO show a single adapter needed to achieve the 1024 ONU target. Thanks to Adtran, in particular Holger Hildebrandt, Michael Pagenkopf, Torsten Thieme, Matteo Scandolo and Andrea Campanella. 
  • Augmented Testing capabilities with manual patch testing with DT workflow and new tests: enabled OLT Disable/Enable tests, OLT and ONU soft reboot thanks to Andy Bavier, Suchitra Vemuri, Girish Gowdra, Hardik Windlass and Andrea Campanella. 
  • Included changes to ONOS Readiness/Liveliness probes to check for required ONOS apps, ensures all are active.
  • Introduced BBSIM support for TT workflow, thanks to Matteo Scandolo, Serkant Uluderya and the BBsim Brigade.
  • Various bug-fixes and scale improvements, thanks to the BBSim Brigade. 
  • Ongoing design discussions on a number of items including software upgrades, error handling, mac-learning and use of P4 based AGG switches. Thanks to Ciena, Netsia, Radisys and ONF.

Stratum

  • Max Pudelko (ONF) contributed bug fixes and built system enhancements.

Trellis

  • Continued to improve TOST integration into Aether:
    • Demonstrated TOST SDE and deployment automation.
    • Fixed pod readiness issue.
    • Integrating TOST logs with Aether EFK stack.
    • Improving TOST image building process.
