Overview

Fast Path Baseline is the foundation of the fast path packet processing framework.

Features

• Physical port detection

• Logical interface abstraction

• Statistics

• Internal debugging

• Plugins

• MACVLAN devices support in the fast path

• Ability to offload linux egress packets to the fast path

• NUMA awareness (e.g. for LAG)

Dependencies

6WINDGate modules

• FPN-SDK Baseline

Linux
