This is to align with monolithic/FAPI, where we get slot indications in each slot. In the nFAPI, this is replaced by timing information, such that the VNF ticks automatically, and gets indications from the PNF on early/late messages. The timing information handling is not implemented in the present nFAPI implementation. Instead, we adopt the FAPI behavior and send timing information in every slot, abusing it to be a slot indication.
This directory contains the NFAPI code.
It comes in two parts:
1 - open-nFAPI
This is a clone of the github repository
(https://github.com/cisco/open-nFAPI,
commit b3bc579b1697eab829d5d8a2de59c93a61b88fa4).
The patch open-nfapi.oai.patch has then been applied.
2 - oai_integration
This is code written by David Price from Cisco to integrate
open-nFAPI into OpenAirInterface.
