中文摘要	Node importance evaluation based on the number of alternative routes in a communication network cannot accurately reflect the importance of the nodes when the network is split into several disconnected parts. An improved node importance evaluation method was developed based on performance decreasing grads. In this method, the node importance is evaluated by calculating the diameter variation end the connection ratio decrease of the network when the node is disconnected. The algorithm is compared with the alternative route-based algorithm for the ARPA net topology. The results show that this method accurately represents the node importance, both when the network is split into several unconnected parts and when the network is connected as one part.
