UDP throughput and Latency

asked 2021-09-10 07:57:39 +0000

Hello Team. I used Wireshark to capture traffic in Contiki Cooja Simulator. Basically, I am working with CoAP and MQTT-SN protocols which are UDP based. I need to get from Wireshark the throughput and latency of the packets. How can I get this? I wanted to use the I/O graph but I was told that's not the way to calculate the throughput. Please if you have an idea how to get throughput and latency for UDP packets, kindly respond.

Thank you.

regards, Fikayo

I/O graphs might work for you. But all you can get from a packet capture is the actual throughput during the capture. Will that be sufficient for you?

Thanks for the response, Hugo. I already presented my throughput results with the I/O graph but it was discarded by my supervisor. He says there is a better way to get throughput and Latency in Wireshark. I then found out one can get throughput and RTT for TCP streams but didn't find any for UDP. Unfortunately, I/O graphs won't be sufficient for me.

Unlike TCP, UDP doesn't require a datagram to be acknowledged. Wireshark can graph TCP round-trip by TCP steam.
