使用UDP时路由器无响应 [英] Router gets unresponsive when using UDP
问题描述
我正在开发多人游戏.原理很简单，两个播放器中的每个播放器每隔50毫秒周期性地互相发送512字节.
I'm working on a multiplayer game. The principle is simple, each of the two players sends each other periodically 512 bytes every 50 milliseconds.
问题在于，大约每20-30秒，玩家就会停止接收数据，有时会持续一秒，有时甚至会长达20秒(尽管发送并未中断).
The problem is that about every 20-30 seconds players stop receiving data for sometimes one but sometimes even up to 20 seconds (though, sending had not been interrupted).
起初，我认为这是由于我或用于调试的远程PC一侧的网络连接速度慢所致.
At first I thought that this is caused by a slow network connection on either my side or on the side of my remote PC which I use for debugging.
但是后来我注意到，在游戏停止接收数据的同时，我这一边的所有网络流量都变慢了.
But then I noticed that all network traffic on my side slows down at the same times when the game stops receiving data.
所以我开始了ping <my-local-router>，这就是给我看的:
So I started ping <my-local-router> and this is what it shows me:
When the game isn't running:

似乎游戏正在导致路由器无响应.
It seems that the game is causing the router to become unresponsive.
我的本地PC上没有运行任何P2P，但这听起来似乎没有任何意义，因为在游戏不运行时我没有遇到后备状态.
I don't have any P2P running on my local PC, but that doesn't even sound relevant since I don't experience the slowback when the game isn't running.
我是UDP编程的新手，对此我一无所知，尤其是因为每50毫秒512字节对我来说似乎是一个很小的带宽(当我运行P2P时，它很容易以1.5MB/s的速度运行).
I'm new to UDP programming and I'm getting clueless with this, especially since the 512 bytes every 50ms seems like quite a small bandwidth to me (when I do run P2P, it easily runs 1.5MB/s).
推荐答案
这可能是我的路由器快要死了，需要替换或无线驱动程序中有些杂物，因为我发现最近有更多的网络死机，甚至在应用程序未运行.
This might have been my router dying and needing a replacement or something fishy in my wireless drivers, as I've noticed more network freezes lately even at times when the application wasn't running.
