摘　　要：针对海量配电终端接入的路由存储开销问题,文章提出一种基于分布式哈希表(distributed hash table,DHT)标识的配电数据网路由优化方法。首先分析工业以太网构建的配电数据网低存储开销的技术需求;然后通过引入DHT存储设备接入信息和Chord快速查找哈希表等策略,设计基于DHT标识的低存储开销的路由优化方法;最后通过实验仿真验证所提方法性能的有效性。实验仿真结果表明,所提方法具有存储开销小、额外时延小、额外信道占用比例小等优点。Aiming at the routing storage overhead of mass distribution terminal access,a distributed hash table(DHT)-based routing optimization method for distribution data network is proposed.Firstly,the technical requirements of low storage cost of distribution data network constructed by industrial Ethernet are analyzed.Then,by introducing DHT storage device access information and Chord fast lookup hash table,a low storage cost routing optimization method based on DHT identification is designed.Finally,the effectiveness of the proposed method is verified by experimental simulation.The experimental simulation results show that the proposed method has the advantages of low memory cost,low extra delay and small extra channel occupancy ratio.
