Usage

Traffic redirection: latency

Node A:

$ gcc -pthread common.c generator.c -o generator -lrt
$ ./generator -s 10 udp:10.0.0.2:50000 

Node C:

$ python controller.py -n 1000

Displaying results:

$ python plot_latency.py output.txt

Traffic redirection: packet loss

Node B:

$ gcc analyzer.c common.c -o analyzer
$ ./analyzer -s 10 udp:10.0.0.2:50000

Node C:

$ gcc -DHOST_C analyzer.c common.c -o analyzer
$ ./analyzer -s 10 udp:10.0.0.2:50000

Node A:

$ gcc -pthread common.c generator.c -o generator -lrt
$ ./generator -s 10 udp:10.0.0.2:50000 

Node C4:

$ java -jar target/floodlight.jar

Node C1:

$ python controller.py -n 1001

Substitute analyzer.c with analyzer_multistream.c or analyzer_close_up.c or analyzer_second_lowest.c to obtain different results (see paper). Displaying results:

$ python plot.py B.txt C.txt (multi stream case)
$ python plot.py B_output_port.txt C_output_port.txt  (single stream case)

Traffic duplication

Use either of passthrough or duplicate methods within the start method of controller.py to conduct experiments with the respective flow: either simply connect A to B, or duplicate to C and D as well. (Comment the one out that's not needed) Node A:

$ gcc -pthread common.c generator.c -o generator -lrt
$ gcc -shared -lrt -fPIC -I/usr/include/python2.7 -lpython2.7 -o cutils.so cutils.c
$ python server.py

Node B:

$ gcc analyzer.c common.c -o analyzer
./analyzer -s 10 udp:10.0.0.2:50000

Node C4:

$ java -jar target/floodlight.jar

Node C1:

$ python controller.py -n 1001

For multistream tests, make sure to use sockets 50000-50006 when launching the analyzer instances on B, since this is what the controller expects. Displaying results:
