Integration of omec-project UPF's BESS data plane inside PacketRusher

[linouxis9]

Hi,

I'm currently working on an open-source gNB/UE Simulator which can act as 5G Core stress tester to evaluate the performance of the 5G Core, called PacketRusher.
It can stress test a 5G Core both on the control plane and user plane side using a great amount of UEs.

For now, I've been using free5gc's gtp5g kernel module as the GTP-U stack of the tool. However, kernel modules have a lot of shortcomings and I've been looking to replace the GTP-U stack with something else.

Lately, I've been working on integrating eUPF's eBPF code inside HewlettPackard/PacketRusher#47.
However, as PacketRusher is to be a performance-testing tool, I'm interested in also offering something more performant.

As such, I would be interested in integrating your BESS data plane inside PacketRusher.

Do you think it would make sense for a tool like PacketRusher to embed it, eg. PacketRusher would configure PFCP Sessions inside the BESS dataplane to act as a RAN and send traffic toward the 5GC's UPF?

Sorry for the long message :-)

Thanks and cheers,
Valentin

Hi Valentin, thanks for your comment. If I correctly understand your proposal for using PacketRusher to configure sessions in BESS is similar to the UPF's Packet Testing Framework, correct?
Happy to discuss further details about your proposal. Moreover, you can also discuss your proposal in the Slack channel

Hi @gab-arrobo,

Thanks for your quick answer!
The goal is to have a high performant generic N3 tunnel inside PacketRusher, PacketRusher simulates gNodeBs and multiples UEs and then create a network interface for each UE's PDU Session in a dedicated VRF.
The goal is not to have packets generated with Soapy/TRex sent at a high speed against any UPF vendor (it might be a future goal however)
For now, we want PacketRusher to offer a network interface per PDU Session similar to UERANSIM's uesimtun interfaces but with higher performance.
Users can then use iperf3, or whatever application they wish through the tunnel.
We currently have this feature implemented with free5gc's gtp5g, a PoC using eUPF's eBPF code and we are looking at alternatives as well.

PacketRusher is a bit similar to your gnbSim tool, but supports more procedures and can do UE registration in parallel, I hope we can collaborate together :-)

I'll join your slack as well!

Thanks a lot,
Valentin

Hi @gab-arrobo,

As I'm working on this project as an individual on my free time, my email domain is not listed as one of the domains that can be used to sign up on the ONF-Community's Slack, what should I do?

Thanks a lot,

Let me check with the infra team. Are you trying to use the email from your GitHub profile?

I added you to the aether-dev channel. I tried to add you using the email from your GitHub profile to the #general and sdcore-dev channels but I got a message saying that you are already a member.

Hi @gab-arrobo

Sorry for disturbing you.
I'm following the development activity of the both Packet Rusher & SD-CORE project.
Could you help to add me into the ONF slack channel?

Yes, but it seems like @nycu.edu.tw domain hasn't permission to register a new account.

[gab-arrobo]

Ok, thanks for the info. Let me check

Done. You were added to a few channels in the ONF community

Hi @linouxis9,

Let's move this conversation to Slack (probably the aether-dev is the best place to continue our conversation). So, you can have a wider audience about your proposal. Let's us know what input you would need from us.

Thanks!
