Strategy for updating the data of automatic topology discovery
-
摘要: 首先提出了在拓扑发现数据更新中的若干实际问题,然后对这些问题一一给出了解决方案,并提出一种基于状态的拓扑发现更新策略.最后,通过在一个比较大的局域网中的试验,在正确性和效率方面对该策略的性能进行了评价.Abstract: A strategy for updating the data obtained during the process of automatic topology discovery was presented. This strategy can be applied to the changes detected in time with the minimum cost, and several important problems which have to be faced in practice were discussed. In the end, the effectiveness of our approach in terms of correctness and speed of automatic topology discovery were demonstrated, based on an analysis of a large experimental network.
