C ++ UDP套接字数据包排队 [英] C++ UDP sockets packet queuing

问题描述

我使用相同的UDP套接字发送和接收数据.我想知道DGRAM套接字的数据包排队是否已经存在，还是我们必须单独处理它.

I am using the same UDP socket for sending and receiving data. I am wondering if packet queuing for DGRAM sockets is already present, or do we have to handle it separately.

如果用户代码必须处理队列，如何完成?我们是否有单独的线程可以接收套接字的套接字，并将数据包放入reciver_queue中，并从另一个send_queue中发送出去?

If the user code has to handle queueing, how is it done? Do we have separate threads to recvfrom for the socket and put the packet in the reciver_queue and to sendto from another sending_queue?

一个示例代码绝对很棒.感谢您的帮助.

An example code will be absolutely awesome. Thanks for your help.

推荐答案

有一个数据包队列.但是，当数据包队列已满时，UDP数据包开始被丢弃.当它们被丢弃时，它们将永远丢失，因此请确保您继续读取数据！

There is a packet queue. However when the packet queue is filled then UDP packets start getting discarded. When they are discarded they are lost forever so make sure you keep reading data!
