Developer Relations & Communities

Aether 

  • Prateek, Amit, and Pushp from GS Lab have been working on adding metrics to the Aether portal, including enforcing security policies for metrics.
  • Application filtering has been added to the Aether ROC.
  • Slice and Application QoS have been added to the Aether ROC.
  • The Aether ROC can now use Keycloak as an authentication mechanism.
  • Stability has been improved within onos-config, a key component of the Aether ROC.
  • Aether 1.5.2 RC is now deployed on ONF production infrastructure.
  • Many additional system tests have been added to Aether.
  • ONF’s Menlo Lab now includes a deployment of three small cells as well as three slices.
  • Traffic analysis now includes an alarm feature.
  • ONF has begun research into chatbots to be used for natural language processing on the Aether portal.
  • ONF is developing an AI/ML video processing application using OpenVINO, deployed at ONF’s Menlo Lab.
  • ONF is working on automating eNodeB configuration.

SD-RAN

  • Deutsche Telekom has deployed the first fully disaggregated 5G field trial, interconnecting components from over 8 vendors with ONF’s SD-RAN open source RAN Intelligent Controller (nRT-RIC). 
    • As the first full implementation of the O-RAN architecture with RU, DU, CU, RIC, and xApps from a suite of different suppliers, this represents a milestone in the open RAN movement.
    • This event was the first opportunity for the public to hear about the challenges and triumphs of the deployment, gain insight into what is possible with today’s open technologies, and discuss details with the principles in charge of the deployment.
    • Event videos, including keynotes, panels, and talks from the ecosystem can be found here.
  • We released SD-RAN 1.3 with updated versions of our micro-ONOS based nRT-RIC, xApp-SDKs, new xApps, whitebox LTE CU/DU/RU solution, and sdRan-in-a-Box (RiaB).
    • The highlights of this release include two new use case implementations - xApp based Mobile Handovers and RAN Slice Management - as well as the ability to run multiple instances of the E2T microservice for HA and horizontal scalability.
    • As before, we also continue to upgrade the RIC platform to the latest O-RAN specifications  -  this release includes E2 AP 2.0 support while maintaining support for the previous version 1.01.
    • Read more about it in the release notes on the SD-RAN documentation site (ONF member-only access).

SD-Core

  • Sai from the Intel team and Anjana from the Infosys team are working on supporting multiple control plane connections in UPF.
  • Badhrinath from ONF has worked on REST APIs to configure BESS UPF. This work is complete and code is available.   
  • Shubham Joshi from GS Lab is  working on 5G network function profiling work. 
  • ONF and GS Lab team developing gNodeB simulator for 5G development. Vini Gajjar from GS Lab and Ajay Thakur from ONF working on this tool. First version of this simulator is available in SD-Core release helm charts now. The tool now supports Registration, UE Initiated Deregistration, and PDU Session Establishment simulation profiles along with the data plane (uplink and downlink ICMP ping packets).
  • Ruchit from GS Lab team has worked extensively to improve test coverage in SD-Core. Recently we added test cases around QoS.
  • The ONF team has completed Application filtering work and support is available as SD-Core 1.0 development is complete.  As a part of this work, now SD-Core supports multiple FARs, QERs, PDRs per UE. This will give critical features of binding applications to specific slices. Users outside the slice should not be able to access the applications. This code is available and now going through release cycle tests. 
  • ONF team members fixed issues observed in Network Slice Configuration (addition, deletion, and modification). We also fixed issues seen in Device Group Configuration (addition, deletion, and modification).
  • The SD-Core team continues to support various trial efforts.  A number of ONF member companies are using SD-Core in their trials. There were some issues observed during the trial in AMF and SMF. Ankur and Vijaya from the ONF team have fixed the production issues. This makes AMF and SMF more stable.
  • The ONF team upgraded the Aether network with the latest Aether 1.5 Release code. Complete 4G/5G  Network Functions are configured through ROC network slicing APIs. This is a unique feature of SD-Core and available to ONF member.
