How to ensure my udp sockets receive all packets in order? Assuming the packets are guarantee arrive in order at the receiver machine, and no packet drop.
I am asking this because I ran my program many times in window, and redhat. It always receive in-order packets under windows, on the other hand, out-of-order packet always happen under redhat as well as ubuntu.
I am using boost asio library to create 50 udp sockets, receive rate set to 100 packet/sec. I also have tried without boost asio, and use a boost thread to listen to an epoll, and call recv to fd immediately, but yielded the same result. In addition, If I only open 8 sockets in linux, i receive no out-of-order packets.
