互联网流量不对称-如何捕获反向路径问题？(Internet Traffic is Asymmetrical — How to Catch Reverse Path Issues?)

When looking at a traceroute, people often forget that traffic on the Internet is asymmetrical most of the time. It is called the Hot Potato Routing. As soon as an ISP has a packet with a destination address outside its own network, it will try to pass the packet to the next ISP ASAP.

在查看路由时，人们通常会忘记Internet上的流量大部分时间都是不对称的。 这被称为“热土豆路由” 。 一旦ISP在其自己的网络之外具有目的地地址的数据包，它将尝试将该数据包尽快传递给下一个ISP。
