Abstract: As there are shortcomings of the current routing simulation strategy，this paper proposes a routing simulation strategy of global computing and storage for core nodes.The simulation of this strategy is as follows：For the computational complexity，frequent use of the core node，a common method of global calculation and static storage is adopted；but for the simple calculation，infrequent use of edge node，the storage method of one-dimensional array is used.The strategy reduces the routing calculation time effectively and improves the simulation efficiency.Compared with the traditional global calculation static storage，the improved routing strategy reduces the simulation run-time for more than 61%.

摘要： 针对当前路由模拟策略存在的不足，提出了面向核心节点的全局计算与存储的路由模拟策略。该策略思想是：针对计算复杂、使用频繁的核心节点采用全局计算与静态存储的方法；针对计算简单、使用不频繁的边缘节点采用一维数组存储的方法。该策略有效地降低了路由计算时间，提高了模拟的运行效率。与传统的全局计算与静态存储策略相比，改进的路由策略模拟运行时间减少61%以上。
