中文摘要：

本文从一个全新的视角去研究汇聚节点的拓扑特性，首次利用拓扑势在城域传送网络下评估汇聚节点。结果显示具有较高的精确性，为设计人员在选择新的汇聚节点上提供了新的思路，且对现网已有汇聚节点合理性的后评估存在参考价值。

英文摘要：

This paper is the first time that topology potential is used to evaluate convergent nodes from MAN transmission network. The experiment results show that the method for evaluating convergent nodes has high accuracy, it also provides a new train of thought for designers to choose a new convergent node.In addition, there is a great reference value based on the post-evaluation for the rationality of existing convergent nodes in present network.
