Android的UDP数据包丢失 [英] Android UDP packet loss

问题描述

所以我写发送为5Kb通过UDP数据包出15次第二的应用程序。我明白，我会失去一些数据包，但我似乎是第几秒钟后，我失去所有的数据包。即使我慢下来到为5Kb数据包发送每10秒一次，我还是会失去他们。什么会导致此？

So i'm writing an app that sends 5Kb packets out 15 times a second through UDP. I understand I will lose some packets but I seem to be losing all my packets after the first couple seconds. Even if I slow it down to send the 5Kb packets out once every 10 seconds I will still lose them. What would cause this?

推荐答案

这并不奇怪，他们都在下降。有效载荷<一个href=\"http://stackoverflow.com/questions/1098897/what-is-the-largest-safe-udp-packet-size-on-the-internet\">bigger大于512字节是不可能做出来的网络。这取决于你的路由器MTU的多少带宽分配给UDP /互联网流量的路由器上。

It's not surprising that they are all dropped. A payload bigger than 512 bytes is unlikely to make it out of the network. It depends on the MTU of your router and how much bandwidth is allocated to UDP / internet traffic on the router.
