-Network Topology for testing VNFs
----------------------------------
-The ethernet cables should be connected between traffic generator and the VNF server (BM,
-SRIOV or OVS) setup based on the test profile.
-
-The connectivity could be
-1. Single port pair : One pair ports used for traffic 
-   ::
-     e.g. Single port pair link0 and link1 of VNF are used
-     TG:port 0 ------ VNF:Port 0
-     TG:port 1 ------ VNF:Port 1
-
-2. Multi port pair :  More than one pair of traffic
-   ::
-     e.g. Two port pair link 0, link1, link2 and link3 of VNF are used
-     TG:port 0 ------ VNF:Port 0
-     TG:port 1 ------ VNF:Port 1
-     TG:port 2 ------ VNF:Port 2 
-     TG:port 3 ------ VNF:Port 3

-Traffic generator and VNF Setup details
-----------------------------------------
-
-step 0:  Preparing hardware connection.
-         Connect Traffic generator and VNF system back to back as shown in previous section e.g. Bare-Metal Configuration
-         TRex port 0 ↔ (VNF Port 0) ↔ (VNF Port 1) ↔ TRex port 1
-
-step 1: Setting up Traffic generator (TRex) (Refer: https://trex-tgn.cisco.com/trex/doc/trex_stateless_bench.html)
-        TRex Software preparations
-        --------------------------
-        a. Install the OS (Bare metal Linux, not VM!)
-        b. Obtain the latest TRex package: wget https://trex-tgn.cisco.com/trex/release/latest
-        c. Untar the package: tar -xzf latest
-        d. Change dir to unzipped TRex
-        e. Create config file using command: sudo python dpdk_setup_ports.py -i
-           In case of Ubuntu 16 need python3
-           See paragraph config creation for detailed step-by-step
-step 2: Setting up VNF
-
-        Deployment type - Bare-Metal:
-        ----------------------------
-        a. Clone sampleVNF project repository  - git clone https://git.opnfv.org/samplevnf
-        Auto Build
-          * Interactive options: 
-                ./tools/vnf_build.sh -i
-                Follow the steps in the screen from option [1] –> [9] and select option [8] to build the vnfs. It will automatically download selected DPDK version and any required patches and will setup everything and build VNFs.
-                Following are the options for setup:
-                ----------------------------------------------------------
-                Step 1: Environment setup.
-                ----------------------------------------------------------
-                [1] Check OS and network connection
-                [2] Select DPDK RTE version
-
-                ----------------------------------------------------------
-                Step 2: Download and Install
-                ----------------------------------------------------------
-                [3] Agree to download
-                [4] Download packages
-                [5] Download DPDK zip
-                [6] Build and Install DPDK
-                [7] Setup hugepages
-
-                ----------------------------------------------------------
-                Step 3: Build VNFs
-                ----------------------------------------------------------
-                [8] Build all VNFs (vACL, vCGNAPT, vFW, UDP_Replay, DPPD-PROX)
-
-                [9] Exit Script
-          * non-Interactive options:
-                ./tools/vnf_build.sh -s -d=<dpdk version eg 17.02>
-        Manual Build
-           1. Download DPDK supported version from dpdk.org
-              http://dpdk.org/browse/dpdk/snapshot/dpdk-$DPDK_RTE_VER.zip
-              unzip dpdk-$DPDK_RTE_VER.zip and apply dpdk patches only in case of 16.04 (Not required for other DPDK versions)
-              cd dpdk
-              make config T=x86_64-native-linuxapp-gcc O=x86_64-native-linuxapp-gcc
-              cd x86_64-native-linuxapp-gcc
-              make
-           2. Setup huge pages
-              For 1G/2M hugepage sizes, for example 1G pages, the size must be
-              specified explicitly and can also be optionally set as the
-              default hugepage size for the system. For example, to reserve 8G
-              of hugepage memory in the form of eight 1G pages, the following
-              options should be passed to the kernel: * default_hugepagesz=1G
-              hugepagesz=1G hugepages=8 hugepagesz=2M hugepages=2048
-           3. Add this to Go to /etc/default/grub configuration file.
-              Append “default_hugepagesz=1G hugepagesz=1G hugepages=8 hugepagesz=2M hugepages=2048”
-              to the GRUB_CMDLINE_LINUX entry.
-           4. Setup Environment Variable
-              export RTE_SDK=<samplevnf>/dpdk
-              export RTE_TARGET=x86_64-native-linuxapp-gcc
-              export VNF_CORE=<samplevnf>
-              or using ./tools/setenv.sh
-           5. Build vFW VNFs
-              cd <samplevnf>/VNFs/vFW
-              make clean
-              make
-              The vFW executable will be created at the following location
-              <samplevnf>/VNFs/vFW/build/vFW
-
-step 3: Running VNF
-  a. Setup Port to run VNF
-        For DPDK versions 17.xx
-        1. cd <samplevnf>/dpdk
-        2. ./usertools/dpdk-devbind.py --status <--- List the network device
-        3. ./usertools/dpdk-devbind.py -b igb_uio <PCI Port 0> <PCI Port 1>
-        .. _More details: http://dpdk.org/doc/guides-17.05/linux_gsg/build_dpdk.html#binding-and-unbinding-network-ports-to-from-the-kernel-modules

+Network Topology for testing VNFs
+---------------------------------
+The ethernet cables should be connected between traffic generator and the VNF server (BM,
+SRIOV or OVS) setup based on the test profile.
+
+The connectivity could be
+1. Single port pair : One pair ports used for traffic
+   ::
+     e.g. Single port pair link0 and link1 of VNF are used
+     TG:port 0 ------ VNF:Port 0
+     TG:port 1 ------ VNF:Port 1
+
+2. Multi port pair :  More than one pair of traffic
+   ::
+     e.g. Two port pair link 0, link1, link2 and link3 of VNF are used
+     TG:port 0 ------ VNF:Port 0
+     TG:port 1 ------ VNF:Port 1
+     TG:port 2 ------ VNF:Port 2
+     TG:port 3 ------ VNF:Port 3
+
+ * Bare-Metal

+
+Setup Traffic generator
+-----------------------
+
+Step 0: Preparing hardware connection::
+        Connect Traffic generator and VNF system back to back as shown in previous section
+        TRex port 0 ↔ (VNF Port 0) ↔ (VNF Port 1) ↔ TRex port 1
+
+Step 1: Setting up Traffic generator (TRex) ::
+        (Refer: https://trex-tgn.cisco.com/trex/doc/trex_stateless_bench.html)
+        TRex Software preparations
+        ^^^^^^^^^^^^^^^^^^^^^^^^^^
+        a. Install the OS (Bare metal Linux, not VM!)
+        b. Obtain the latest TRex package: wget https://trex-tgn.cisco.com/trex/release/latest
+        c. Untar the package: tar -xzf latest
+        d. Change dir to unzipped TRex
+        e. Create config file using command: sudo python dpdk_setup_ports.py -i
+           In case of Ubuntu 16 need python3
+           See paragraph config creation for detailed step-by-step
+
+
+Build SampleVNFs
+-----------------
+Step 2: Procedure to build SampleVNFs::
+   a) Clone sampleVNF project repository  - git clone https://git.opnfv.org/samplevnf
+   b) Build VNFs
+      Auto Build
+      ^^^^^^^^^^
+          * Interactive options:
+                ./tools/vnf_build.sh -i
+                Follow the steps in the screen from option [1] –> [9] and select option [8] to build the vnfs.
+                It will automatically download selected DPDK version and any required patches and will setup everything and build VNFs.
+                Following are the options for setup:
+                ----------------------------------------------------------
+                Step 1: Environment setup.
+                ----------------------------------------------------------
+                [1] Check OS and network connection
+                [2] Select DPDK RTE version
+
+                ----------------------------------------------------------
+                Step 2: Download and Install
+                ----------------------------------------------------------
+                [3] Agree to download
+                [4] Download packages
+                [5] Download DPDK zip
+                [6] Build and Install DPDK
+                [7] Setup hugepages
+
+                ----------------------------------------------------------
+                Step 3: Build VNFs
+                ----------------------------------------------------------
+                [8] Build all VNFs (vACL, vCGNAPT, vFW, UDP_Replay, DPPD-PROX)
+
+                [9] Exit Script
+          * non-Interactive options:
+                ./tools/vnf_build.sh -s -d=<dpdk version eg 17.02>
+      Manual Build
+      ^^^^^^^^^^^^
+           1. Download DPDK supported version from dpdk.org
+              http://dpdk.org/browse/dpdk/snapshot/dpdk-$DPDK_RTE_VER.zip
+              unzip dpdk-$DPDK_RTE_VER.zip and apply dpdk patches only in case of 16.04 (Not required for other DPDK versions)
+              cd dpdk
+              make config T=x86_64-native-linuxapp-gcc O=x86_64-native-linuxapp-gcc
+              cd x86_64-native-linuxapp-gcc
+              make
+           2. Setup huge pages
+              For 1G/2M hugepage sizes, for example 1G pages, the size must be
+              specified explicitly and can also be optionally set as the
+              default hugepage size for the system. For example, to reserve 8G
+              of hugepage memory in the form of eight 1G pages, the following
+              options should be passed to the kernel: * default_hugepagesz=1G
+              hugepagesz=1G hugepages=8 hugepagesz=2M hugepages=2048
+           3. Add this to Go to /etc/default/grub configuration file.
+              Append “default_hugepagesz=1G hugepagesz=1G hugepages=8 hugepagesz=2M hugepages=2048”
+              to the GRUB_CMDLINE_LINUX entry.
+           4. Setup Environment Variable
+              export RTE_SDK=<samplevnf>/dpdk
+              export RTE_TARGET=x86_64-native-linuxapp-gcc
+              export VNF_CORE=<samplevnf>
+              or using ./tools/setenv.sh
+           5. Build VNFs
+              cd <samplevnf>
+              make
+              or to build individual VNFs
+                cd <samplevnf>/VNFs/
+                make clean
+                make
+                The vFW executable will be created at the following location
+                <samplevnf>/VNFs/vFW/build/vFW

+PROX - How to run
+---------------------
+
+Description
+-----------
+This is PROX, the Packet pROcessing eXecution engine, part of Intel(R)
+Data Plane Performance Demonstrators, and formerly known as DPPD-BNG.
+PROX is a DPDK-based application implementing Telco use-cases such as
+a simplified BRAS/BNG, light-weight AFTR... It also allows configuring
+finer grained network functions like QoS, Routing, load-balancing...
+
+Compiling and running this application
+--------------------------------------
+This application supports DPDK 16.04, 16.11, 17.02 and 17.05.
+The following commands assume that the following variables have been set:
+
+export RTE_SDK=/path/to/dpdk
+export RTE_TARGET=x86_64-native-linuxapp-gcc
+
+Example: DPDK 17.05 installation
+--------------------------------
+git clone http://dpdk.org/git/dpdk
+cd dpdk
+git checkout v17.05
+make install T=$RTE_TARGET
+
+PROX compilation
+----------------
+The Makefile with this application expects RTE_SDK to point to the
+root directory of DPDK (e.g. export RTE_SDK=/root/dpdk). If RTE_TARGET
+has not been set, x86_64-native-linuxapp-gcc will be assumed.
+
+Running PROX
+------------
+After DPDK has been set up, run make from the directory where you have
+extracted this application. A build directory will be created
+containing the PROX executable. The usage of the application is shown
+below. Note that this application assumes that all required ports have
+been bound to the DPDK provided igb_uio driver. Refer to the "Getting
+Started Guide - DPDK" document for more details.
+
+Usage: ./build/prox [-f CONFIG_FILE] [-l LOG_FILE] [-p] [-o DISPLAY] [-v] [-a|-e] \
+		[-m|-s|-i] [-n] [-w DEF] [-q] [-k] [-d] [-z] [-r VAL] [-u] [-t]
+        -f CONFIG_FILE : configuration file to load, ./prox.cfg by default
+        -l LOG_FILE : log file name, ./prox.log by default
+        -p : include PID in log file name if default log file is used
+        -o DISPLAY: Set display to use, can be 'curses' (default), 'cli' or 'none'
+        -v verbosity : initial logging verbosity
+        -a : autostart all cores (by default)
+        -e : don't autostart
+        -n : Create NULL devices instead of using PCI devices, useful together with -i
+        -m : list supported task modes and exit
+        -s : check configuration file syntax and exit
+        -i : check initialization sequence and exit
+        -u : Listen on UDS /tmp/prox.sock
+        -t : Listen on TCP port 8474
+        -q : Pass argument to Lua interpreter, useful to define variables
+        -w : define variable using syntax varname=value
+             takes precedence over variables defined in CONFIG_FILE
+        -k : Log statistics to file "stats_dump" in current directory
+        -d : Run as daemon, the parent process will block until PROX is not initialized
+        -z : Ignore CPU topology, implies -i
+        -r : Change initial screen refresh rate. If set to a lower than 0.001 seconds,
+                  screen refreshing will be disabled
+
+While applications using DPDK typically rely on the core mask and the
+number of channels to be specified on the command line, this
+application is configured using a .cfg file. The core mask and number
+of channels is derived from this config. For example, to run the
+application from the source directory execute:
+
+  user@target:~$ ./build/prox -f ./config/nop.cfg
+
+Provided example configurations
+-------------------------------
+PROX can be configured either as the SUT (System Under Test) or as the
+Traffic Generator. Some example configuration files are provided, both
+in the config directory to run PROX as a SUT, and in the gen directory
+to run it as a Traffic Generator.
+A quick description of these example configurations is provided below.
+Additional details are provided in the example configuration files.
+
+Basic configurations, mostly used as sanity check:
+- config/nop.cfg
+- config/nop-rings.cfg
+- gen/nop-gen.cfg
+
+Simplified BNG (Border Network Gateway) configurations, using different
+number of ports, with and without QoS, running on the host or in a VM:
+- config/bng-4ports.cfg
+- config/bng-8ports.cfg
+- config/bng-qos-4ports.cfg
+- config/bng-qos-8ports.cfg
+- config/bng-1q-4ports.cfg
+- config/bng-ovs-usv-4ports.cfg
+- config/bng-no-cpu-topology-4ports.cfg
+- gen/bng-4ports-gen.cfg
+- gen/bng-8ports-gen.cfg
+- gen/bng-ovs-usv-4ports-gen.cfg
+
+Light-weight AFTR configurations:
+- config/lw_aftr.cfg
+- gen/lw_aftr-gen.cfg
