| Sample and benchmark scripts for pktgen (packet generator) |
| ========================================================== |
| This directory contains some pktgen sample and benchmark scripts, that |
| can easily be copied and adjusted for your own use-case. |
| |
| General doc is located in kernel: Documentation/networking/pktgen.txt |
| |
| Helper include files |
| ==================== |
| This directory contains two helper shell files, that can be "included" |
| by shell source'ing. Namely "functions.sh" and "parameters.sh". |
| |
| Common parameters |
| ----------------- |
| The parameters.sh file support easy and consistant parameter parsing |
| across the sample scripts. Usage example is printed on errors:: |
| |
| Usage: ./pktgen_sample01_simple.sh [-vx] -i ethX |
| -i : ($DEV) output interface/device (required) |
| -s : ($PKT_SIZE) packet size |
| -d : ($DEST_IP) destination IP. CIDR (e.g. 198.18.0.0/15) is also allowed |
| -m : ($DST_MAC) destination MAC-addr |
| -p : ($DST_PORT) destination PORT range (e.g. 433-444) is also allowed |
| -t : ($THREADS) threads to start |
| -f : ($F_THREAD) index of first thread (zero indexed CPU number) |
| -c : ($SKB_CLONE) SKB clones send before alloc new SKB |
| -n : ($COUNT) num messages to send per thread, 0 means indefinitely |
| -b : ($BURST) HW level bursting of SKBs |
| -v : ($VERBOSE) verbose |
| -x : ($DEBUG) debug |
| |
| The global variable being set is also listed. E.g. the required |
| interface/device parameter "-i" sets variable $DEV. |
| |
| Common functions |
| ---------------- |
| The functions.sh file provides; Three different shell functions for |
| configuring the different components of pktgen: pg_ctrl(), pg_thread() |
| and pg_set(). |
| |
| These functions correspond to pktgens different components. |
| * pg_ctrl() control "pgctrl" (/proc/net/pktgen/pgctrl) |
| * pg_thread() control the kernel threads and binding to devices |
| * pg_set() control setup of individual devices |
| |
| See sample scripts for usage examples. |
