如果你感觉上网速度非常缓慢,不要立刻怪罪给你提供接入服务的ISP,因为有可能你所访问的信息绕了好长一段路才来到你家。在Internet中,数据的传送是通过网中许多段的传输介质和设备(如:路由器,交换机,服务器,网关等)从一端到达另一端。每一个连接在网络上的设备,一般情况下都会有一个独立的IP地址。通过Tracert我们可以知道数据是怎样从你的计算机到达互联网另一端的主机。虽然每次数据包由某一同样的出发点(source)到达某一同样的目的地(destination)走的路径可能会不一样,但基本上来说大部分时候所走的路由是相同的。
If you feel very slow on the Internet, do not blame ISPs for providing access to you right away because it is possible that the information you are visiting may have come a long way to your home. In the Internet, data is transmitted from one end to the other through many segments of transmission media and devices (eg, routers, switches, servers, gateways, etc.) in the network. Each connected to the network equipment, under normal circumstances will have a separate IP address. With Tracert we know how data is coming from your computer to the host on the other side of the Internet. Although each packet may travel from some same source to some same destination, the paths may vary, but basically the routes are mostly the same.
