    • A method of generating network identifiers for use by mobile routers of a moving network is provided which enables fast and efficient routing loop avoidance and detection. The method comprises receiving at a mobile router of a sub-network chain, a beacon from a preceding mobile router in the chain, the beacon containing a network identifier of the preceding mobile router, generating a new network identifier by applying a pre-defined function to the received network identifier, and including the new network identifier in beacons broadcast by the receiving mobile router. When preparing for a handover, a mobile router compares the network identifier contained in a received beacon with values generated by applying said function against its own network identifier. This allows the mobile router to identify beacons originating from mobile routers that are downstream in the same chain.
    • 提供了一种生成移动网络的移动路由器使用的网络标识符的方法,其实现快速且有效的路由环路回避和检测。 该方法包括在子网链路的移动路由器处接收来自链路中的先前移动路由器的信标,所述信标包含前一移动路由器的网络标识符,通过应用预定义功能来生成新的网络标识符 到接收到的网络标识符,并且在接收移动路由器广播的信标中包括新的网络标识符。 当准备切换时,移动路由器将包含在接收的信标中的网络标识符与通过根据其自己的网络标识符应用所述功能而生成的值进行比较。 这允许移动路由器识别源自同一链路下游的移动路由器的信标。
