由周期sendto()/recvfrom() delay造成的UDP套接字的周期延迟峰值，用于Linux rt -抢占系统

I have setup two Raspberry Pis to use UDP sockets, one as the client and one as the server. The kernel has been patched with RT-PREEMPT (4.9.43-rt30+). The client acts as an echo to the server to allow for the calculation of Round-Trip Latency (RTL). At the moment a send frequency of 10Hz is being used on the server side with 2 threads: one for sending the messages to the client and one for receiving the messages from the client. The threads are setup to have a schedule priority of 95 using Round-Robin scheduling.I have setup two Raspberry Pis to use UDP socke
