Python Code to Analyze Network Latency Using Packet Capture Between Precisely Synchronized Nodes.
To use the code some python3 and some python3 packages are required.To install required packages run:
pip3 install -r requirements.txtto analyze the pcaps e.g., sender.pcap and receiver.pcap generated from nodes having IP addresses 10.10.10.1 and 10.10.10.2 respectively run the following command:
python3 analyze.py -sp sender.pcap -rp receiver.pcap -hy log -n experiment_1 -sip 10.10.10.1 -rip 10.10.10.2The code will generate histogram of latencies (in miliseconds).
Script help is available with -h flag.
python3 analyze.py -hoptional arguments:
-h, --help show this help message and exit
--sender_pcap SENDER_PCAP, -sp SENDER_PCAP
