摘要
电力OTN网络是智能电网的通信主干网,因此节点性能评价是保证电力通信主干网运行的关键技术之一。文章考虑为保障业务可靠性的电力OTN网络路径成环规划的特殊性,将业务路径成环特性作为节点评价指标,提出了一种基于最小环收缩的电力OTN网络节点评估方法。该方法综合考虑了节点的成环特性以及所成最小环的路径对节点性能评价的影响,通过网络聚合度策略实现电力OTN节点评价。最后以实际电力OTN网络为例,采用模拟攻击法实验验证了方法的有效性。
Power OTN network is the backbone of communication in smart grid, so the evaluation of node performance is one of the key technologies to ensure the operation of power communication backbone network. In consideration of special ring path planning of OTN network for the service reliability, using business loop characteristics as the node evaluation index, this paper proposed a power OTN network node evaluation method based on minimum ring contraction. This method takes into account influence of the ring characteristics of node and the minimum ring path to the evaluation of node, realizes the OTN node evaluation through the network polymerization degree strategy. Taking the actual power OTN network as an example, the simulation attack method is used to verify the effectiveness of the proposed method.
