Service Priority Based Traffic Scheduling Method in Smart Grid Distribution and Consumption Communication Network

无线公网通信技术是智能配用电通信网关键技术之一。为了避免网络中由于流量并发而出现拥塞现象,本文提出了一种基于业务优先级的流量调度方法。首先通过分析智能配用电通信网中传输的不同业务信息呈现从上到下层级树的流量模型,接着将不同种类的流量根据业务重要性和通信需求划分优先级,最后,提出了基于业务优先级的流量调度和排队方法。结果显示,本文提出的流量调度和排队方法能够有效地减小网络时延。

Wireless public network communication technology is one of the key technologies of smart grid distribution and consumption communication network for smart grid. To avoid the congestion in the network due to concurrent traffic, this paper proposed a traffic scheduling method based on service priority. Firstly, the traffic model from top to bottom level tree was presented by analyzing the different service information transmitted in the smart distribution network. Then, the traffic of different types was classified according to their importance and communication demand. Finally, the method of traffic scheduling and queuing based on service priority was proposed. The result showed that the proposed method can effectively reduce the network delay.
