Packet loss rate between dpdk_udp_stability and linux-udp #104

Hi. ANS Team.

I have some question about packet loss of the UDP When i try to send streaming data from server app base on dpdk_udp_stability to client app base on linux-udp. (1:1) Of course, I modified these Test App for the test. However, It seems like there are many packet loss in linux-udp receiver side. (There is no packet loss in kernel to kernel API in my PC) Anyone who know why? And Is there some way to increase translate rate?

Anyone who know how to reduce packet loss for UDP over DPDK?

No more inforamtion, no comments. You may tcpdump packets on linux side. You can check statis in ans by anscli.
