1 Sample and benchmark scripts for pktgen (packet generator)
2 ==========================================================
3 This directory contains some pktgen sample and benchmark scripts, that
4 can easily be copied and adjusted for your own use-case.
6 General doc is located in kernel: Documentation/networking/pktgen.txt
10 This directory contains two helper shell files, that can be "included"
11 by shell source'ing. Namely "functions.sh" and "parameters.sh".
15 The parameters.sh file support easy and consistant parameter parsing
16 across the sample scripts. Usage example is printed on errors::
18 Usage: ./pktgen_sample01_simple.sh [-vx] -i ethX
19 -i : ($DEV) output interface/device (required)
20 -s : ($PKT_SIZE) packet size
21 -d : ($DEST_IP) destination IP. CIDR (e.g. 198.18.0.0/15) is also allowed
22 -m : ($DST_MAC) destination MAC-addr
23 -p : ($DST_PORT) destination PORT range (e.g. 433-444) is also allowed
24 -t : ($THREADS) threads to start
25 -f : ($F_THREAD) index of first thread (zero indexed CPU number)
26 -c : ($SKB_CLONE) SKB clones send before alloc new SKB
27 -n : ($COUNT) num messages to send per thread, 0 means indefinitely
28 -b : ($BURST) HW level bursting of SKBs
29 -v : ($VERBOSE) verbose
32 The global variable being set is also listed. E.g. the required
33 interface/device parameter "-i" sets variable $DEV.
37 The functions.sh file provides; Three different shell functions for
38 configuring the different components of pktgen: pg_ctrl(), pg_thread()
41 These functions correspond to pktgens different components.
42 * pg_ctrl() control "pgctrl" (/proc/net/pktgen/pgctrl)
43 * pg_thread() control the kernel threads and binding to devices
44 * pg_set() control setup of individual devices
46 See sample scripts for usage examples.
