The number of hops a message takes along a route is called the hop count.

消息沿路由经过的跳数称为跳数。

Keeping track of the hop count is useful because it can help identify routing problems.

跟踪跳数非常有用，因为它可以帮助识别路由问题。

If you start seeing messages with high hop counts, you can bet something has gone awry in the routing!

如果您开始看到具有高跳数的消息，您可以打赌路由中出现了问题！

This kind of error can be detected because the hop count is stored with the message and updated along its journey.

这种错误可以被检测到，因为跳数与消息一起存储并在其旅程中更新。
