Simple traffic generator to xmit flows with some throughput distribution patterns

flowgen (Flow Generator)

Description

flowgen is simple traffic generator for multiple UDP flows with some throughput distribution patterns.

flowgen support 3 flow distribtuion patterns.

• Same : the ratio of bandwidth for each flow is uniform.
• Random : the ratio of bandwidth for each flow is random.
• Power-law : the ratio of bandwidth for each flow follows power-law.

flowgen uses Linux raw socket to transmit UDP packets. It is really slow.

Compile

 git clone https://github.com/upa/flowgen.git
 cd flowgen
 make
 ./flowgen -h

make DCE=yes is defined for ns-3-dce use.

How to use

 usage: ./flowgen
 	-s : Source IP address (default 10.1.0.10)
 	-d : Destination IP address (default 10.2.0.10)
 	-n : Number of flows (default 10)
 	-t : Type of flow distribution {same|random|power} (default same)
 	-l : Packet size (excluding ether header 14byte)
 	-i : packet send interval (micro second)
 	-m : Seed of srand
 	-f : daemon mode
 	-r : Randomize source ports of each flows
 	-c : Number of xmit packets (defualt unlimited)
 	-e : Receive mode
 	-u : using UDP socket instead of raw socket
 	-w : Run WITH receive thread

 % sudo ./flowgen
 
 or 
 
 % sudo ./flowgen -s 172.16.15.10 -d 172.16.12.12 -n 30 -t power -l 1500 -r -f
