hi all I am working with a module which claims to send packets every 100 micro seconds . but when I examine the incoming packets in wireshark i see that the intervals between incoming packets are about 400 usec. I am not sure the problem is due to whether the module or the wireshark program estimation function how can i find it out ? is there any other approach to find the transfer rate of my module ? thanks alot This question is marked "community wiki". asked 12 Dec '10, 01:17  makarbasi edited 12 Dec '10, 01:19 |
One Answer:
Is there a way that you can determine if there are any packets missing in a layer above IP? If so, you can capture over time and do the math to determine time/packets = interval. This would get you something to check by. Also, worth mentioning is the pcap-ng format to get nanosecond level precision. I guess that doesn't fully rule out all of your concerns (I guess hw latency could still be a factor), but maybe worth a try. answered 12 Dec '10, 07:52  Paul Stewart |
