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

Make sure that PKG_CONFIG_PATH is configured properly.

git clone https://github.com/carvalhof/udp_generator
cd udp_generator
make

Make sure that LD_LIBRARY_PATH is configured properly.

sudo ./build/udp-generator -a 41:00.0 -n 4 -c 0xff -- -r $DISTRIBUTION -r $RATE -f $FLOWS -s $SIZE -t $DURATION -q $QUEUES -c $ADDR_FILE -o $OUTPUT_FILE

Example

sudo ./build/udp-generator -a 41:00.0 -n 4 -c 0xff -- -r exponential -r 100000 -f 1 -s 128 -t 10 -q 1 -c addr.cfg -o output.dat

• $DISTRIBUTION : interarrival distribution (e.g., uniform or exponential)
• $RATE : packet rate in pps
• $FLOWS : number of flows
• $SIZE : packet size in bytes
• $DURATION : duration of execution in seconds (we double for warming up)
• $QUEUES : number of RX/TX queues
• $ADDR_FILE : name of address file (e.g., 'addr.cfg')
• $OUTPUT_FILE : name of output file containg the latency for each packet
