summary

Norma implements a practical network load tester on programmable switch ASICs (Tofino) with a stateful protocol abstraction mapped into the pipeline, a multi-queue reply generator to produce custom payloads, and a coordinated meter/register multi-stage rate controller for precise rate and burst control. It generates up to 3 Tbps TCP, ~3.2 Tbps aggregate (32×100G), and 1 Tbps HTTP in tests, runs in Alibaba production for two years, and detects tens of performance issues in real devices.
