忧虑的Skype用户急于获得一个适当的后备计划给一些其他的互联网电话服务商带来严重的损伤, 因为他们的信息流量迅速增加了.
The scurry by worried Skype users to get a backup plan in place crippled a number of other internet telephony services as traffic to them suddenly rocketed.
另外，如果某些提供信息的组件没有提供任何与缓存相关的信息，则可以使用后备机制的全局设置，不过这一点没有在此表中得到体现。
Also, though not reflected in this table, there are global Settings for fallback mechanisms if some of the contributing components do not provide any caching-related information.
只有当没有后备路由存在时，才丢弃数据分组，并且向源节点发送一个路由错误信息，这时再由源节点发起一次路由寻找过程。
Package discarding is occurred when no backup routings exist in node cache, and a route error message is send to source node, then a new routing discover process will begin.
