NAME

       trafgen - a high-performance zero-copy network packet generator

SYNOPSIS

       trafgen	 [-d|--dev <netdev>][-c|--conf <file>][-J|--jumbo-support]	[-x|--interactive][-n|--num <uint>][-r|--rand][-t|--gap <usec>]
	    [-S|--ring-size <size>][-k|--kernel-pull <usec>][-b|--bind-cpu <cpu>]      [-B|--unbind-cpu
       <cpu>][-H|--prio-high][-Q|--notouch-irq][-v|--version]	   [-h|--help]

DESCRIPTION

       A high-performance network traffic generator that uses the zero-copy TX_RING for network I/O. For instance, on comodity Gigabit hardware up
       to 1,488,095 pps 64 Byte pps have been achieved with trafgen.

OPTIONS

       trafgen --dev eth0 --conf trafgen.txf --bind-cpu 0
	   Use packet configuration trafgen.txf, eth0 as transmission device and CPU0 for binding the process.

OPTIONS

       -h|--help
	   Print help text and lists all options.

       -v|--version
	   Print version.

       -d|--dev <netdev>
	   Device for transmission i.e., eth0.

       -c|--conf <conf>
	   Path to packet configuration file.

       -x|--interactive
	   Start trafgen in interactive mode.

       -J|--jumbo-support
	   Support for 64KB Super Jumbo Frames

       -n|--num <uint>
	   Number of packets to generate before exiting.  0 means forever until SIGINT.

       -r|--rand
	   Randomize packet selection process instead of round-robin.

       -t|--gap <uint>
	   Interpacket gap in microseconds.

       -S|--ring-size <size>
	   Manually set ring size to <size>: mmap space in KB/MB/GB.

       -k|--kernel-pull <uint>
	   Kernel pull from user interval in microseconds.  Default value is 10 microseconds.

       -b|--bind-cpu <cpu>
	   Bind to specific CPU (or CPU-range).

       -B|--unbind-cpu <cpu>
	   Forbid to use specific CPU (or CPU-range).

       -H|--prio-high
	   Make this high priority process.

       -Q|--notouch-irq
	   Do not touch IRQ CPU affinity of NIC.

EXAMPLES

       Generate traffic defined in trafgen.txf on eth0 using CPU 0
	   trafgen --dev eth0 --conf trafgen.txf --bind-cpu 0

       Generate traffic on eth0 using CPU 0, wait 100 us between packets
	   trafgen --dev eth0 --conf trafgen.txf --bind-cpu 0 --gap 100

       Generate 100,000 packet on eth0 using CPU 0
	   trafgen --dev eth0 --conf trafgen.txf --bind-cpu 0 --num 100000
