In addition Paul Ruth has developed soft p4 switch deployments that work in the VM today already. They use hardware interfaces (100Gbps and 25Gbps ports) depending on how you configure the VM.
Hello,
We are working to deploy qty 4 P4 switches (EdgeCore Wedge with 100Gbps ports and a Tofino chipset). We are also deploying 25 Xilinx dual 100Gbps port U280 FPGAs (roughly one per site) for which a P4 toolchain exists (we are in the process of proving the toolchain). So the answer to your question depends entirely on what you are trying to do.

UCSD site was cutoff through some network misconfiguration, which by now has been remedied as far as I know.
This is something we need to look at – I would have expected it to work at least for dedicated NICs, maybe not SR-IOV. Can you use tc tool to limit the bandwidth?
Sites are connected by a combination of dedicated optical 100Gbps links and ‘best-effort’ L2 links from Internet2. The intent is to have all sites eventually connected at 100Gbps. Can you describe your usecase? There are things you can do with e.g. tc tool in linux to limit the bandwidth of the interface.
Not currently. We’ve discussed this option but have not implemented it yet. This requires some additional support in the control framework. We’ll see if we can add it to Rel.1.5
Thank you @yoursunny – this is the recommended way. W.r.t. cm.fabric-testbed.net @thoang – you should see a ‘Login’ button in upper right when you visit cm.fabric-testbed.net – so in order to interact with it you need to login first.
We checked – the “:” is not liked by the network control service. For release 1.4 we are adding regex checkers for different element names – they will have different regexes depending on what’s allowed for the particular topology element class and will flag as soon as you set the name, so no need to wait for submit.
Thanks we will check. Most likely we will tighten the regex for setting the name in the first place.
Ertza,
I know for a fact we have folks using DPDK on the testbed with all three NIC types:- All three NIC models are compatible with DPDK in PCI mode (PCI mode is the most efficient one).
- The default_ubuntu_22 OS image comes with linux-image-virtual kernel package that lacks mlx5_ib kernel module. DPDK cannot initialize the NIC without this kernel model. The solution is installing linux-image-generic kernel package.
If you want SmartNIC, please have you or one of the project owners fill out a request for permissions to get SmartNICs. This is in the Portal project view.

Please look over these articles

before proceeding. Keep in mind enrollment is a human-in-the-loop process with multiple steps, including confirming your email.
We are going to make these sites (STAR and MAX) unavailable for the time being. Unfortunately we are not able to resolve the issue quickly.
