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 : ($DEST_IP) destination IP
|
||
|
|
-m : ($DST_MAC) destination MAC-addr
|
||
|
|
-t : ($THREADS) threads to start
|
||
|
|
-c : ($SKB_CLONE) SKB clones send before alloc new SKB
|
||
|
|
-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.
