TCP_generator

Follow these instructions to build the tcp generator using DPDK 22.11 and CloudLab nodes

Building

Make sure that PKG_CONFIG_PATH is configured properly.

git clone https://github.com/carvalhof/tcp_generator
cd tcp_generator
PKG_CONFIG_PATH=$HOME/lib/x86_64-linux-gnu/pkgconfig make

Running

Make sure that LD_LIBRARY_PATH is configured properly.

sudo LD_LIBRARY_PATH=$HOME/lib/x86_64-linux-gnu ./build/tcp-generator -a 3b:00.0 -n 4 -c 0xff -- -d $DISTRIBUTION -r $RATE -f $FLOWS -s $SIZE -t $DURATION -e $SEED -c $ADDR_FILE -o $OUTPUT_FILE -D $SRV_DISTRIBUTION -i $SRV_ITERATIONS1 -j $SRV_ITERATIONS2 -m $SRV_MODE

Example

sudo LD_LIBRARY_PATH=$HOME/lib/x86_64-linux-gnu ./build/tcp-generator -a 3b:00.0 -n 4 -c 0xff -- -d exponential -r 100000 -f 1 -s 128 -t 10 -e 37 -c addr.cfg -o output.dat -D constant -i 0 -j 0 -m 0

Parameters

• $DISTRIBUTION : interarrival distribution (e.g., uniform, exponential, pareto, or lognormal)
• $RATE : packet rate in pps
• $FLOWS : number of flows
• $SIZE : packet size in bytes
• $DURATION : duration of execution in seconds
• $SEED : seed number
• $ADDR_FILE : name of address file (e.g., 'addr.cfg')
• $OUTPUT_FILE : name of output file containg the latency for each packet
• $SRV_DISTRIBUTION : fakework distribution in the server side (e.g., constant, exponential, or bimodal)
• $SRV_ITERATIONS1 : iterations of the fakework in the server side
• $SRV_ITERATIONS2 : iterations of the fakework in the server side (only for bimodal)
• $SRV_MODE : mode for bimodal (only for bimodal)
