Thanks alot for putting this together, I think it is a great start. There is currently no mention of what type of topology is being used though, I do not want to complicate things, but I do think we need to at least gauge what is used behind the numbers being presented, as it would have consequences for how we lay out the tests, and consequently what we scale for. I think these should cover the most normal cases: Gateway topologies: * Distributed gateways with distributed FIPs * Distributed gateways with centralized NAT * Centralized gateways IP topologies: * Project networks mainly use IPv4 RFC1918 and SNAT/DNAT * Project networks mainly use routed IPv4 (no NAT) * Project networks mainly use routed IPv6 (no NAT) Any suggestions for how to tie these into the questionnaire without causing a matrix explosion? -- Frode Nordahl > Best regards, > Dumitru > > [0] https://mail.openvswitch.org/pipermail/ovs-dev/2023-May/405089.html > _______________________________________________ dev mailing list [email protected] https://mail.openvswitch.org/mailman/listinfo/ovs-dev
