Hi,
I am just writing my first a traffic generator code.
The program sends predefined quantity of frames(Ethernet/IP/UDP) in each
seconds. It use 2 loops 1 for seconds the other for the packets in each
second.
for sending I use a while loop
sent=0;
while (sent==0){
sent = rte_eth_tx_burst(eth_id, 0, &pkts, 1);
}
for reviving
recv = rte_eth_rx_burst(eth_id, 0, pktr_burst2, 10);
in the initialization phase I put the packet in the mbuf. In the UDP data
filed is a counter which increasing in every second(with this I would like
to identify the possible packet drops er sec bases)
with lower load the program works fine but close to 100% of performance
Forward frames sent: 8000000
Forward frames received: 8000336
Reverse frames sent: 8000000
Reverse frames received: 7990793
Results in 1 sec sent 800000 recvd 799972 and difference -28
Results in 2 sec sent 800000 recvd 799888 and difference -112
Results in 3 sec sent 800000 recvd 800000 and difference 0
Results in 4 sec sent 800000 recvd 800000 and difference 0
Results in 5 sec sent 800000 recvd 800000 and difference 0
Results in 6 sec sent 800000 recvd 800000 and difference 0
Results in 7 sec sent 800000 recvd 800120 and difference 120
Results in 8 sec sent 800000 recvd 799880 and difference -120
Results in 9 sec sent 800000 recvd 800000 and difference 0
Results in 10 sec sent 800000 recvd 800476 and difference 476
It received more packets than sent.
Are there any solution to fix this issue?
Many Thanks,
Peter
