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
