跟踪路由与 ping 时间差异
trace route vs ping time differences
当我 ping 一个 IP 地址时,平均时间是 71.1 毫秒
当对同一个 ip 使用 tracert 时,显示的时间要长得多(每个节点大约 70 毫秒......),你能解释一下差异吗?

我认为您误解了 traceroute 的输出。每条线代表一个跃点,每个跃点有 3 次尝试(三列)。中间跃点可能有相当高的时间,因为像生成 ICMP 错误消息这样的事情对于路由器来说是一个相当低的优先级,它会在有时间的时候到达它,但它的优先级实际上是路由数据包。
你的最后一行是源到目的的完整路径,3次相当于你的ping时间
