Hello, I have been trying to measure the round trip latency with two machines, A->B->A. I modified l2fwd as two new apps: rx and tx, where tx sends packets and embeds time stamp, rx receives packets and calculate the round trip latency. The source code are as follows: https://github.com/kay21s/dpdk/tree/master/examples/rx https://github.com/kay21s/dpdk/tree/master/examples/tx
Both of rx and tx run correctly if only one app is running. However, when I am trying to run rx and tx simultaneously on machine A, rx cannot receive any packets. The commands I used are sudo ./build/tx -c 0x2 -n 1 --file-prefix p2 -m 64 -- -q 1 -p 1 sudo ./build/rx -c 0x1 -n 1 --file-prefix p1 -m 64 -- -q 1 -p 1 Thanks for your help, Kai
