CSCui20002 – SSI knpusim
Feature Changes
Fastpath NPU Simulator
To improve overall performance, the user space npusim (NPU simulator) process for packet processing is now
supplemented by a new kernel space knpusim process.
supplemented by a new kernel space knpusim process.
Previous Behavior: Packet processing was performed exclusively by npusim which required a buffer copy and transmit
to the loopback interface. This required additional buffer copies and loopback transmits to transfer packets between user
space processes (slowpath processing).

space processes (slowpath processing).
New Behavior: The knpusim process is a kernel loadable Linux module. It processes internally transferred socket
buffers that do not require copying (fastpath processing). Packets that cannot be fully dispositioned by knpusim are sent
to the user space npusim process.
