摘要
有文献提出采用二层触发器提前触发三层切换的方法以适应移动IP中的实时应用,但是现有的方法存在指示不准确、触发方法不明确等问题。为此,给出了新的二层触发器方法,并给出具体的路由更新协议DRPR,从而消除了移动节点(MN)切换时的注册时延。
In order to satisfy real-time applications, L2-Trigger has been proposed to trigger layer 3 handoff ahead to decrease the handoff delay of mobile IP. But some problems such as misty indications and ambiguous trigger techniques have been found in former methods. A new L2-Trigger method and a routes updating protocol named Double Routes Pre-Registration were put forward. This method will eliminate the registration delay when Mobile Node （MN） moves from one network to another.
