nFAPI is a network functional application platform interface that separates the MAC and PHY layers. It defines procedures for initializing, configuring, restarting, and resetting the PNF and PHY instances. The presentation demonstrates the nFAPI initialization procedure which moves the PNF from an idle state to a running state through a configured state by having the VNF collect PNF information, updating the PNF configuration, and creating PHY instances. It also discusses testing the nFAPI implementation using a server and client model between the VNF and PNF on an OAI platform.
