Aether 

In this month’s Aether update, we are focusing on Aether Operational Platform and Applications

• Enhanced automation of the POD deployment process and used it to deploy Aether at all Pronto sites.
• Enhanced runtime operational control portal with additional unit and scaling tests.
• Pronto network monitoring and alerts dashboard enhanced to facilitate achieving progressively higher nines availability goals set forth for the upcoming quarters.
• Improved automated CI/CD toolchain with infrastructure-as-code principles.
• Work commenced on developing security tools for Aether control and management.
• Demonstrated two edge applications (Motion Capture and Command Control) that collectively enable closed-loop control of autonomous drone flight formations on the Pronto POD operationalized at Stanford Flight Lab. Connectivity between the edge applications and the drones have been established using Aether’s 4G/5G connectivity services that make use of 4G CBRS dongles on drones, Aether small cells, and Aether’s SD-Fabric and SD-Core components.

Ambassador Program

• The CALA Ambassador team is hosting a webinar, "Working with ONF to Transform Mobile and Broadband Networks in LATAM". The webinar will be delivered May 11th in Spanish and May 13th in Portuguese. Register to attend.

COMAC+OMEC

• 5GC NF image building is integrated with Jenkins CI. Also we cleanup the Makefiles and Dockerfile for each NF.
• We moved webconsole folder from 5gc repo to a dedicated repo as other NFs.
• Started to set up the 5GC Xn based handover test environment with NG4T.
• We wrote both override value files of the helm chart for both staging deployment and Radisys deployment of 5GC. 

Developer Relations

• Check out our latest Community Member Profile blog post:
  • David Bainbridge
• See all community contributions in the ONF Community Dashboard.

OIMT

• Continued exploring updates to the Physical inventory model.
• Identifying areas to focus on in OIMT to support security in the ONF interface, especially TAPI, and considering relevant use cases for the following:
  • Control/reporting of security in the network
  • Control/reporting of security for the management-control system
  • Securing a stream
  • Streaming security information
  • Dealing with security concerns for a view/slice (access control etc.)
    • When building the view
    • When accessing information in the view
    • When streaming a view

ONOS/µONOS

• Fixed an issue in the ONOS application store that prevented some drivers from being loaded correctly.

OTCC

• TAPI subproject held a virtual face-to-face meeting April 12, 13 and 15 with Andrea Mazzini (Nokia) and Karthik Sethuraman (NEC) leading. 
  • Work was done on path computation service, physical route and optical impairments, alarms, OTU, OMS and ODU modeling
  • Key contributions came from Ramon Casellas (TEF/CTTC), Nigel Davis (Ciena) and Andrea
  • There was a presentation on the EU PASSION Project by Prof. Pierpaolo Boffi (Politecnico di Milano)

P4

• The P4 Workshop is being held as a virtual event May 18-20th. Check out the great line-up of live keynotes and on-demand talks on the agenda. It’s free to join us so sign-up now!

SD-RAN

• SD-RAN Community continues to grow. In April we kicked off two new collaborations.
  • We are working with Radisys CU/DU integration with ONF’s micro-ONOS based nRT-RIC. Initial focus is on the KPM-v2 Service Model (SM), standardized by O-RAN
  • We also started working on a new use-case for Mobile Handovers with Intel Labs. The initial focus was on the development of a pre-standard SM for this use case
• Aside from the new collaborations, we continue to work with Facebook and AirHop towards
  • Upgrading our SON based use-case (PCI conflict resolution) to incorporate 5G nodes
  • Develop modifications to the RC-PRE Service Model to incorporate changes that allow for Mobility Load Balancing (MLB)
• We continue to collaborate with O-RAN WG-3. Based on their clarifications for the KPM v2 SM, we patched the SD-RAN release we made end-of-Q1 to incorporate Action Definition Format 1. These patches were released as SD-RAN v1.1.1

SEBA/VOLTHA

• Various bug fixes and improvements in the Opeonu-go, thanks to Adtran, ONF, Netsia
  • Alarm management
  • Soft reboot
  • Flow deletion 
  • Error reporting
  • Performance Metrics
• Added ONU and OLT reboot tests for TT, thanks to ONF
• Refreshed Image protos with voltctl implementation for ONU software updates to support download, commit, activate separate procedures, thanks to ONF, Radisys and Adtran
• Enhanced DMI interface with gRCP streams for Events and Alarms thanks to the team at Radisys
• First contributions to the Open Device agent and Open Device manager thanks to the team at Radisys
• Move to keyword based pipeline with the new voltha-infra and voltha-stack charts for better support and future compatibility

Stratum

• Max Pudelko (ONF) contributed many improvements and bug fixes, including build system clean up, dependency upgrade (Abseil March 2021, gRPC 1.33.6, Protobuf 3.14.0, BF SDE 9.5.0), and Stratum-BfRt enhancements (deflect on drop, SDE logging and error handling).
• Stratum no longer supports port 28000 for gRPC connections by default. You should use port 9339 (gNMI) or 9559 (P4Runtime) instead. Because Stratum uses a single gRPC server, either port number works for both services. To override the default port at runtime, use the -external_stratum_urls flag.

Trellis

• Minor fixes and platform improvements
• Deployment pipeline improvement - wait until previous resources are cleaned up completely before launching new instances.
• Diagnostic pipeline improvement - now support capturing Karaf log as well
