Abstract

Power communication network is very important for the management of the power system. With the exponential growth of the power equipment and the drastic increase in the amount of power monitoring data, there is a huge challenge for the smart network access of the power communication network. Then, software defined network (SDN) which is flexible and scalable is suitable for the power communication network. In order to increase the high quality of service (QoS) of provided communication for users, the traffic QoS sensing is the key of the smart network access in the power communication network. Then, we propose a SDN-Based active measurement method to measure the evaluation parameters of the smart network access in the power communication network. Firstly, we introduce the instructions provided by the OpenFlow protocol, which can be used to collect statistics from OpenFlow switches. Secondly, we define the parameters that should be measured in the power communication network to evaluate the performance of the network and give the corresponding measurement method with them. Next, we proposed a SDN-based active measurement algorithm that updates its measurement interval based on the measurement throughput changes. Finally, we built a simulation platform using the Mininet simulator and the POX controller to verify the proposed measurement method, and the simulation results show the accuracy of our proposed method and the measurement load of our proposed method are both better than that of Polling measurement methods.

摘要

电力通信网络对于电力系统的管理非常重要。随着电力设备的指数级增长和电力监控数据量的急剧增加，电力通信网络的智能网络接入面临巨大挑战。然后，灵活且可扩展的软件定义网络（SDN）适用于电力通信网络。为了提高为用户提供的通信的高质量服务（QoS），流量QoS传感是电力通信网络中智能网络访问的关键。然后，我们提出了一种基于SDN的主动测量方法来测量电力通信网络中智能网络访问的评估参数。首先，我们介绍OpenFlow协议提供的说明，可用于从OpenFlow交换机收集统计信息。其次，我们定义了电力通信网络中应该测量的参数，以评估网络的性能，并给出相应的测量方法。接下来，我们提出了一种基于SDN的主动测量算法，该算法根据测量吞吐量的变化来更新其测量间隔。最后，我们使用Mininet模拟器和POX控制器构建了一个仿真平台，对所提出的测量方法进行了验证，仿真结果表明，所提出的方法的准确性和测量负荷均优于轮询测量方法。 。我们定义了电力通信网络中应该测量的参数，以评估网络的性能，并给出相应的测量方法。接下来，我们提出了一种基于SDN的主动测量算法，该算法根据测量吞吐量的变化来更新其测量间隔。最后，我们使用Mininet模拟器和POX控制器构建了一个仿真平台，对所提出的测量方法进行了验证，仿真结果表明，所提出的方法的准确性和测量负荷均优于轮询测量方法。 。我们定义了电力通信网络中应该测量的参数，以评估网络的性能，并给出相应的测量方法。接下来，我们提出了一种基于SDN的主动测量算法，该算法根据测量吞吐量的变化来更新其测量间隔。最后，我们使用Mininet模拟器和POX控制器构建了一个仿真平台，对所提出的测量方法进行了验证，仿真结果表明，所提出的方法的准确性和测量负荷均优于轮询测量方法。 。
