摘要
为了提高电力通信接入系统网络切片虚拟资源分配和调度能力,提出基于SDN技术的电力通信接入系统网络切片虚拟资源分配算法。设计电力通信接入系统网络切片虚拟资源存储结构,结合特征空间重组技术重组资源结构。利用语义相关性融合的方法提取资源特征,进行模糊聚类处理。通过SDN技术实现网络切片虚拟资源的自适应分配和优化调度,根据虚拟资源的网格分区聚类和属性分类结果实现资源优化分配。仿真实验表明,该方法的网络切片虚拟资源分配的自适应性较好,特征分辨能力较强,提高了电力通信接入系统网络切片虚拟资源分配和调度能力。
In order to improve the power communication access system network slice virtual resource allocation and scheduling capabilities,a power communication access system network slice virtual resource allocation algorithm based on SDN technology is proposed.The virtual resource storage structure of power communication access system is designed,and the resource structure is reorganized by combining the feature space recombination technology.Semantic correlation fusion is used to extract resource features and carry out fuzzy clustering.SDN technology is used to realize adaptive allocation and optimal scheduling of virtual resources in network slices,and resource optimal allocation is realized according to grid partition clustering and attribute classification results of virtual resources.The simulation results show that the proposed method has better adaptability to virtual resource allocation in network slices and better feature resolution ability,which improves the ability of virtual resource allocation and scheduling in power communication access system network slices.
