nfapi/README

+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.

+# open-nFAPI
+ 
+Open-nFAPI is implementation of the Small Cell Forum's network functional API or nFAPI for short. 
+nFAPI defines a network protocol that is used to connect a Physical Network Function (PNF) 
+running LTE Layer 1 to a Virtual Network Function (VNF) running LTE layer 2 and above. The specification
+can be found at http://scf.io/documents/082.
+ 
+The aim of open-nFAPI is to provide an open interface between LTE layer 1 and layer 2 to allow for
+interoperability between the PNF and VNF & also to facilitate the sharing of PNF's between
+different VNF's
+
+Open-nFAPI implements the P4, P5 and P7 interfaces as defined by the nFAPI specification. 
+* The P5 interface allows the VNF to query and configure the 'resources' of the PNF; i.e slice it into
+ 1 or more PHY instances.
+* The P7 interface is used to send the subframe information between the PNF and VNF for a PHY instance
+* The P4 interface allows the VNF to request the PNF PHY instance to perform measurements of the surrounding network
+
+The remaining interfaces are currently outside of the scope of this project.
+
+Supports release 082.09.05 of the nFAPI specification
+
+**The Small Cell Forum cordially requests that any derivative work that looks to 
+extend the nFAPI libraries use the specified vendor extension techniques, 
+so ensuring the widest interoperability of the baseline nFAPI specification 
+in those derivative works.**
+
+## Awards
+
+The Open-nFAPI project has won the Small Cell Forum Judges Choice award 2017. (http://www.smallcellforum.org/awards-2/winners-2017/)
+
+## Licensing
+
+The open-nFAPI libraries are release by CISCO under an Apache 2 license. See `LICENSE.md` file for details
+
+## Downloading
+
+The open-nFAPI project can be pulled from git hub
+
+```
+git clone https://github.com/cisco/open-nFAPI.git nfapi
+```
+
+The following dependencies are required. These are based on a fresh ubuntu installation.
+
+```
+sudo apt-get install autoconf
+sudo apt-get install gcc
+sudo apt-get install g++
+sudo apt-get install libtool
+sudo apt-get install make
+sudo apt-get install doxygen
+sudo apt-get install libcunit1-dev
+sudo apt-get install libz-dev
+sudo apt-get install libsctp-dev
+sudo apt-get install libboost-all-dev
+```
+
+
+
+## Building
+
+To build the open-nFAPI project
+
+```
+autoreconf -i
+./configure
+make
+```
+
+To run the unit and integration tests
+
+```
+make check
+```
+
+You may notice in the console output of the final integration tests the following
+
+```
+*** Missing subframe 123 125
+```
+
+Out of the box the machine on which you are running has not be configured for real time operation as a result
+the vnf may not be scheduled at the correct times and hence it may risk 'missing' subframe opportunities. This
+warning indicates this has happened. 
+
+## Running the simulator
+
+The vnf and pnf simulator can be run using the following commands. The pnf and vnf simulator support sourcing and sinking
+data over udp. Review the xml configuration files for the details of the port and address to configure. Console logging will show
+which address:port is being used
+
+Note : Pinning the simulators to unused cores will produce more consistent behaviour.
+
+Note : You may have to run the processes with sudo to be able to set the real time scheduling and priority
+
+### vnf simulator
+
+To run the vnf simulator you need to specify the port the vnf will listen for p5 connection request upon and also the xml configuration file
+
+```
+vnfsim <port> <xml config file>
+```
+
+### pnf simulator
+
+To run the vnf simulator you need to specify the addrss & port the pnf will connect to the vnf on and also the xml configuration file

+```
+pnfsim <address> <port> <xml config file>

+## eNB Integration - Open Air Interface
+
+The open-nFAPI implementation has been integrated with the Open Air Interface solution here (https://gitlab.eurecom.fr/oai/openairinterface5g) and is (at the time of writing) here (https://gitlab.eurecom.fr/daveprice/openairinterface5g/tree/nfapi-ru-rau-split). The open-nFAPI implementation is integrated with the source eNB implementation with any changes required applied as a patch on top of the baseline open-nFAPI library. Any extensions required must be implemented through the vendor extensions as specified by the Small Cell Forum documentation. Any integration wrapping of functionality must be done within the target environment as shown in the Open Air Interface implementation nfapi directory which is defined by the $NFAPI_DIR location at the top level.
