AT&T bought the Vyatta product from Brocade and developed on the DPDK Brocade Vyatta 5600 version. The software was renamed DANOS. So if it performs like other DPDK routers, you can expect about 10 Gbps of throughput per XEON 2600v4 or newer core you allocate to it. Other closed source DPDK router products are able to do 100+ Gbps with appropriate CPU and network interface resources. This would make it the first opensource fully functioning DPDK based router. The CLI configuration is slightly different even from the last vyatta 5600 version released but easy to adapt to if familiar with vyos or ubiquiti edgeos.

AT&T is using it in production in various locations and roles. News articles reference IP Infusion as the vendor offering commercial support but it seems they may only support the cellsite gateway router. https://www.fiercetelecom.com/telecom/at-t-sets-a-date-to-drop-danos-into-linux-foundation-names-ip-infusion-as-reseller

I'm only an enthusiast and not affiliated with the project.
