LF Anti-trust
We will start by mentioning the project's Antitrust Policy, which you can find linked from the LF and project websites. The policy is important where multiple companies, including potential industry competitors, are participating in meetings. Please review and if you have any questions, please contact your company legal counsel. Members of the LF may contact Andrew Updegrove at the firm Gesmer Updegrove LLP, which provides legal counsel to the LF.
Welcome all. new attendees. If you have any questions about participating in this community, please contact Louis Illuzzi (lilluzzi@linuxfoundation.org).
Invitation to Collaborate on the Agenda and Discussion Topics
In an effort to get even more community input on the agenda and the discussion topics we are using the groups.io mailing list to send an invitiation to contribute to the meeting agenda. The invitations are set to go on the Monday prior to each bi-weekly meeting.
Hardik Jain from GXC provided an overview of ORAN. Slides here.
Facts & Highlights-
Tested up to 1 gigabit per second. Speed is dependent on the UE being used and can go higher
Not yet optimized for latency. Current set achieves sub 10 millisecond latency.
Current setup can support 3 O-RU per 1 DU. This is increasing with each release.
Currently integrated with Magma 5G core
Open questions-
Processing delay at DU and CU
What Use Cases can be shown?
What components are needed and what components may be missing to build a demonstrable PoC.
What configuration interface does GXC support? ORAN interfaces or proprietry?
Proposed Use Case (Yogen)- Performance Measurement from an ORAN perspective as well as end-to-end to optimiize the RAN network. Considered from the SMO side. End to End slicing can be supported.
Proposed Use Case (Paul/American Tower)- would be interested in a combination of public and private cloud (hybrid network) with the private side used for IoT, robotics, etc. and the public side connectivty that can handle private sliced network use cases like Ultra-Reliable Low Latency Communications (URLLC), but at the same time allowing us to enable wireless service providers to also partake of the network. In a perfect world, we should be able to publish Public Land Mobile Network (PLMN) IDs for the private network, each one with its own set of capacity and latency requirements, but also set aside capacity for wireless service providers traditional use cases.
Next steps-
Building Blocks/Proof Points:
Deployment through Anuket and Kubernetes to instantiate CU/DU functions (Muddasar)
Day 1 configuration/alignment of CU/DU
What configuration interface does GXC support?
Orchestration from ONAP through CU/DU (Yogen)
Proof Point 1- Deployment of K8 workloads without any function (Muddasar)
Proof Point 2 -Deployment of workload specific to the core and specific to RAN (Muddasar)
Proof Point 3 -Can workloads be configured? (Muddasar)
Proof Point desired outcomes: (Muddasar)
5G Core is deployed and configured
RAN is deployed and configured
UE simulator can joint the network and access the services (SMS, voice, data)
with; Problem Statement and how is the problem solved, user stories, interaction with other open source projects and components.

ORAN SMO Package demo followup
Muddasar Ahmed (Mitre)- Asked about non-functional requirements; "security orchestration". Ranny suggests we will need to have the capability to demostrate security capabilities. Ranny suggests a security "champion" needs to step foreward. Potential for a security SIG under the Advisory Council
Radio- GenXcomm/UNH/Wavelabs- radio HW requirements, Wavelabs India lab setup.
ORAN -Service Management Orchestration (SMO) Framework- demo to show capabilities, and plan out next steps for 5G SBP
ORAN-SC implementation in the lab- what is available today? What is on the horizon?
Integrations:
GenXcomm with ONAP (ONAP working as a SMO)
GenXcomm with Magma
GenXcomm with Anuket
Work Stream Updates

Action Items (open)
Kader Khan, Parthiban Nalliamudali , Benjamin Posthuma begin work setting up radio components in Wavelabs lab. Can radio be shipped to Wavelabs in Hyderbad? GXC-radios working with Magma. Testing of all Magma 5G capabiliites underway. Other radio vendor DMW
Tracy Van Brakle extend invitation to other operator members of ORAN (i.e. Verizon)
Heather Kirksey Reach out to outreach committee on Magma Slack #magma-outreach-committee to discuss joint marketing opportunities.
Tracy Van Brakle Any link to Multi-Operator RAN from Dec 2021? Referenced on a previous call.
Alex Stancu Can help with ORAN implementation. Martin- what is the success criteria? Agenda item for Deep Dive meeting?
Here is the list of requirements to support ONAP/Magma Integration, supported by Neil Hoff (OPS 5G Customer):
We want to move forward with our Network slicing use case therefore we would like to know if there is any feedback on the presentation (ONAP/Magma Service Assurance Integration – KPIs) made by Jorge Hernandez-Herrero last year
What would be the Magma KPIs to support Network Slicing?
During our Integration with Magma, an issue has been identified: Magma K8s resources need to be installed in different namespaces, and therefore be split into separate Helm packages. Is there a delivery date from Magma to deliver it? thanks
Workstreams
ONAP/Magma Integration #1
- Update from Aarna: The action item is to try workaround in Helm charts on ONAP Istanbul release. We have been facing challenges with ONAP (I release) deployment. On one ONAP deployment on the UNH server where we managed to deploy, the ONAP portal is extremely slow, and takes few minutes to respond. We are trying to install on another server but were unable to allocate new servers due to issues with UNH LaaS setup. These are finally resolved, and we are able to allocate a new server on which we will restart ONAP deployment, and then the workaround to deploy Magma with modified Helm charts.
- CBA and Helm repos. Louis/Yogen need to unstick check-in issue.
- Ran out of time for update
Yogendra: Working on a Helm chart issue by splitting them up. Access gateway. Small infra changes. We'll them be taking up the Magma orchestrator. Is there any specific help from Magma needed (Suresh)? Yes, that would be a great help (orchestrator charts). Suresh and Yogendra to synch offline. Helm chart fixes will require namespace changes (the ideal path). There is also a workaround to force all namespaces to be the same. The community agrees this is not the ideal long-term solution. It was requested that the Magma community, led by Suresh (Wavelabs) work with Yogen to package the Helm charts with namespace corrections as the long-term solution. Suresh to consult with Magma community if this will lead to any conflicts with Magma namespace as it exists today.
ONAP/Magma Topic: #2
Kader - have servers and simulators. Waiting on 5G radio.
- Ran out of time for update
Wavelabs + Rebaca making good progress (in Wavelabs lab) on integration. Before Magma 1.7 come out, we'd like to replicate this in the community labs (by cloning). If using Wavelabs for community use, need to address some issues (e.g. jumphost set up as a trusted host). Can a jumphost be set up at Kaloom and/or UNH? Hanen/Suresh/Amar looking into it. Option may be to connect the labs. Reference- UNH lab is used for 5G resources (Amar).
Magma namespace changes- Namespace changes needed in Magma to resolve Helm chart issue (permanent fix)- Wavelabs/Suresh
What workstreams can begin now that GenXcomm is onboard?
Need to check in with GennXcom and determine RAN side of 5G SBP (CU/DU). Catherine suggestion: Bring this to the ORAN-SC community (Tracy + Martin). LF Staff to make connection.
Lab Resources
UNH- Faraday cage in place.
Kaloom (Montreal) - Hanen, GenXcomm radio is currently at Kaloom lab. Hanen will talk with Ganesh. (Kaloom previously ran the UPF and fabric). Faraday cage in place
Missing radio parts- SW for RAN. If GenXcomm has this, then much easier to deploy
Kader KhanSuresh Krishnan Create requirements document capturing ONAP requirements for Magma (as discussed on 03/08). Requirements doc created
Hardik Jain dedicated resource from GenXcomm to work 5G SBP. Ben will help with resource. Rajesh Ramesh is named resource.

ONAP/Magma Integration - Service Assurance - KPI Network Slicing. This is being tracked by ONAP for Enterprise Task Force. Will come into play in the 5G SBP down the line.
