Hi All, I am newbie to DPDK, and pkt-gen traffic generator. I am doing performance testing and I care about precise timestamps for each packet received and sent out a port.
I see that there is a solution developed here [1]. However it gives about 100ns seconds of precision . My first question is, can we achieve more precision ?? If yes I would like to modify the pktgen code so that each transmitting and received packet is timestamped. Right now I am exploring the example applications like rxtx_callbacks which timestamps packets in DPDK, Is this the right direction to go ? i would highly appreciate any guidance. Thanks all for your time and help. [1] https://github.com/hpcn-uam/iDPDK-Speedometer/tree/release/src ?
