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, 16.11.1, 17.02, 17.05 and 17.08. 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
