Living on the Edge with DCN Networking
summary
Two reference architectures show what’s been built and what actually works: a telco edge using SR-IOV production-ready fast datapath, dual-stack provider networks, VLAN-based router provider networks with segmented VLANs, TLS everywhere, DHCP relay or config-drive for provisioning, and bandwidth partitioning plus minimum-per-VF guarantees for noisy-neighbor protection; and an industrial IoT edge that deploys OVN for distributed DHCP/OVN local services and site-local routing so sites continue serving VMs during central disconnects. Known limits: no stretched L2, unique VLAN ids per site, and some live-migration and DPDK offload features still in progress.
