1. nFAPI continuous integration test documents
1.1 description of continuous integration
(1) The continuous integration configuration file described in this paper refers to the configuration of nFAPI's own integration test. This test can be realized without the L2 and L3 software of the base station.
(2) nFAPI can also be tested through L2. In this test mode, there is a configuration file of the base station, which configures nFAP and the base station. This method is not within the scope of this paper.
(3) The test focuses on the nFAPI protocol stack itself and the functions of PHY and RF under the nFAPI layer, including VNF and PNF, including P5 and P7 interfaces.
(4) nFAPI testing supports one VNF + multiple PNF S
(5) nFAPI testing supports a PNF+ Multiple phys
(6) nFAPI testing supports a PHY + Multiple RFIC s

(2) VNF and PNF run on different machines or virtual machines

Note: the test environment supports one vnf + two PNF S

The most important configuration of VNF is:
- Specify the IP address and port number of P7 and P5 interfaces of VNF
- Timing synchronization mechanism with PNF
- Do you need to collect NFAPI packets in wireshark format

If it is a virtual environment, the most important configuration of PNF is:
- Specify the IP address and port number of P7 and P5 interfaces of VNF
- Timing synchronization mechanism with PNF
- Do you need to collect NFAPI packets in wireshark format
- Other parameters can use the default.
remarks:
- The same PNF can manage multiple PHY entities.
- The same PHY entity can connect multiple RFIC s
- Different RFICs can be different bands or support the same Band. For example, two 2T2R RFICs can be spliced into a 4T4T RFIC

remarks:
Compared with the stand-alone version, the IP addresses of P5 and P7 interfaces of VNF need to be specified in the multi machine version.
