If VNF and PNF are deployed through different processes, it's crucial to maintain synchronization and ensure smooth operation. This commit addresses the need to keep the VNF slot ahead of 2 (as required for network deployment), while ensuring that PNFs wait appropriately to avoid overtaking the slot. Specifically, this involves measuring slot duration and implementing a wait mechanism to ensure that PNFs do not exceed a slot duration of 300 microseconds. This ensures proper smooth operation, especially in the case of RFsim.
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.
