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.
  • Antitrust Policy

Welcome 1st Time Attendees

Welcome all. Please See the 5G SuperBlueprint FAQ. If you have any questions about participating in this effort, please send an email to Brandon Wick (bwick@linuxfoundation.org), Louis Illuzzi (lilluzzi@contractor.linuxfoundation.org) and Heather Kirksey (hkirksey@linuxfoundation.org). 

LFN 5G Cloud Native Network Demo/POC 2021:

Status on current work demo

FlexRAN + Altran RAN + OpenShift Containers Update (Hanen/Rajat/Sam/Amar)

2 Things:

1 Getting the FlexRAN code/binaries: Have components ready for testing. Goal: Run on baremetal first. Adding 2 members to the call (Nidhi, Jianzhu) working to get the openshift environment running in the lab in San Diego. Will provide the binaries after this call. Future: Hanen/Sveto to run the baremetal call in Montreal lab. CentOS 7 container on openshift. Kaloom can dedicate baremetal server. 

2. Getting the Altran, CU/DU containers.

Sriram reached out to RAN team. Haven't heard back (COVID impacts). 

5G Radio Update (Sriram V/Kaloom Team)

Kaloom has been in touch witt Sriram. First step: Testing in lab in Austin, then shipping to Kaloom. After testing complete, will ship to Montreal lab and place in Faraday cage. Possible to FlexRAN up and running next week? That way we have sometime to test the radio against. Sam to provide Jianzhu with the image of the container. 

Question: Is there a diagram (planning) what this version of the demo will entail? Brandon/Amar to start a draft. 

E2E 5G Slicing Update (Sriram R)

Samir. Looking for a resource. Can wait another couple week. Samir/Sriram in contact. 

5G Core initial phase, then E2E testing with emulator. The slices are there, needs testing (reliant upon Altran folks). Will then integrate with UPF.

Sriram has been working with Swami/Lin and weekly slicing calls. Testing on core. 

5G Super Blueprint

Jira / GitHub Update

ONAP Enterprise Working Group Update / Magma Integration (Amar)

Next Steps / AOB

Topics for future calls:

####### Notes from 05/04 and Parking Lot  ###########

LFN 5G Cloud Native Network Demo/POC 2021

From Last time:

FlexRAN + Altran RAN + OpenShift Containers Update (Hanen/Rajat/Sam)

Faraday cage built and ready. Containerization work taking a long time. Option for a work around might be to do a PNF for now (if containerization/orchestration can't be fixed). Hanen/Rajat/Sam to provide an update. FlexRAN Baremetal/PNF option?

Encountered some bumps, node running but external IO issues, compatibility issues. Red Hat is adding another resource work this. Sam inviting them to the mailing list, meeting calendar. A question was raised if we should wait for current container or look for other options (eg. treat as a PNF). CU/DU integration timeline is currently unknown. Currently the CentOS solution, being upgraded. Sam suggests getting started with Amar's suggestion to have another option. Amar and Sam to get this option moving via the Slack channel. 

5G Radio Update (Sriram V)

Radio from GenxComm will be packaged up and shipped to Montreal soon.

Heating issue in radio fixed, waiting for the new radio to be shipped (likely end of this month). Once received in US, needs to be shipped to Montreal. Customs with Canada is usually pretty quick. Brandon to follow up with Sriram V. 

E2E 5G Slicing Update (Sriram R)

From Sriram R:

We have accomplished the first task of linking ONAP slicing flow to Altran 5GC (New Slice creation and activation). We still need to test the new slice configuration (using UE/gnb simulator), and we are in the process of doing this (using Altran's simulator tool). 

Current ONAP + Altran 5GC + Kaloom UPF Demo Setup

We were also told that the UNH lab is now connected to the lab in Montreal, so we can start moving to this. 

The server reservation is extended through the end of July. 

The subsequent tasks (probably can be done in parallel if there is bandwidth): 

1. Test the new slices using UE/gnb simulator (in progress)
2. Test Altran 5GC slicing deployment in Montreal lab (make sure we can accomplish the same thing we did locally in UNH servers)
3. Integration with Kaloom UPF (later)
4. Depending on the community's decision, switch to Rebaca's ABoT simulator  

There was a question raised about when to integrate with Magma. All work with Magma is being done in the 5G Super Blueprint track. The lab set up in Montreal with Kaloom was explained. Kader/Sandeep can help connect LFN with CENGN for additional lab support/consideration. 

Emulator Discussion

2 Options proposed for Emulator:

Context: While we are doing an E2E demo, we need an emulator for showing features on the core. Starting with Altran, looking for additional capabilities from Rebaca. 

Scenario 1:

Two gNB will be created from the Orchestrator. One gNB’s UE will start registration followed by PDU session creation with a slice (NSSAI - application specific value) . The other UE’s from another gNB can register with a different NSSAI and create another PDU session. The DNN may be different for different slice types (applications).

The 5GC core may select different NFs (say different SMF,UPF) for different slices. These NFs will be selected via NSSF and NRF in 5GC.

Then from two gNB’ (UE simulator) , traffic will be sent for two different PDU session over N3 tunnel.

5GC UPF should act differently for different slice specific traffic

Scenario 2:

The same test can be gone with a single gNB. First one UE will register with a slice (NSSAI -sst) value and create a PDU session. Traffic will be sent for that slice over N3.  We can check that slice related traffic is transmitted properly via relevant NFs. Then the UE deregister.

Again the same UE is registered with a different slice (NSSAI – sst) and create PDU session . Again send data over N3 for the new PDU session and check N3 traffic.

Both scenarios ready, Abot install in the environment. After Altran core, we should be able to report, what's working and what's not. 

The Rebaca team will continue to work with Aarna on the integration and report back down the road. 

5G Super Blueprint

• 5G Super Blueprint FAQ 
• Update on Basic Governance

Heather presented an update of our philosophy and approach to the work as an open source community-based initiative. There was a question around inclusion of proprietary components. Things like a compliance program have hard and fast rules, this demo represents more of a community building effort bases on who shows up to contribute (folks signing up to create something in the course of 6-12 months that demo something). We are building something to inspire others. Feedback received that the blueprint needs to be repeatable. The whitepaper until development will match, mirror the work. Challenge will be have something longer term that we can build on. Question of the charter was discussed, option 1, keep it a POC, Option 2, make it legally binding. Maybe, a middle way... mission, vision, mandate to get us started. Decision making traditionally has been around who shows up to make this work. A question was raised about architecture and what our deliverables are. In some cases, we've needed to include commercial pieces to round out our scenarios.
