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

one point three Profile type
(1) Configuration where VNF and PNF run on the same machine or virtual machine
pnf_phy_1_A_ws.xml
vnf_A_ws.xml
(2) VNF and PNF run on different machines or virtual machines
vnf_A.xml => VNF configuration
pnf_phy_1_A.xml => Configuration a of the first PHY
pnf_phy_1_B.xml => Configuration B of the first PHY
pnf_phy_2_A.xml => Configuration a of the second PHY
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
Chapter 3 configuration of VNF and PNF running on the same machine or virtual machine (multi machine version)
three point one VNF configuration
<?xml version="1.0" encoding="UTF-8"?> <vnf> <vnf_p7_list> <vnf_p7> <port>5201</port> <address>192.168.1.28</address> # Specifies the IP address of the P5 interface, which is used to communicate with PNF S that are not on the same machine. <timing_window>10</timing_window> <periodic_timing_enabled>0</periodic_timing_enabled> <periodic_timing_window>0</periodic_timing_window> <aperiodic_timing_enabled>0</aperiodic_timing_enabled> <data> <udp> <rx_port>8891</rx_port> <tx_addr>192.168.1.28</tx_addr> #Specifies the IP address of the P7 interface for communicating with PNF S that are not on the same machine. <tx_port>8892</tx_port> </udp> </data> </vnf_p7> </vnf_p7_list> </vnf>
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.

Compared with stand-alone version, the most important changes are:
- IP address and port number of PNF P5 and P7 interfaces.
