summary

Tencent Cloud replaces monolithic routers with a Disaggregated Software-defined Router that splits access (commodity switches), fast software forwarding, routing on server clusters, and an SDN control plane, and reports running at tens of Tbps. It targets scaling limits like 10 million forwarding tables, uses multiple virtual IPs and horizontal scaling to avoid per-server full-FIBs, implements non-stop forwarding and routing failover, and redirects volumetric DDoS at the access switch to protect servers; authors report years of production operation.
