摘要
为了提高IPv4网络化测控平台的实时性和网络负载均衡性,将新一代IPv6网络引入了测控平台。重点研究了IPv6的新运行模式(即选播模式)在测控网络中的运用策略,探索如何运用IPv6选播运行模式来提升搭建平台的网络性能。通过融合测控选播模式的数学模型并用D-S证据理论进行决策推导,将网络仿真软件OPNET与工业现场状况结合,准确地模拟了实验环境。实验结果表明:IPv6选播运行模式与原有IPv4运行模式相比,网络时延从0.512 ms降低到0.295 ms,极大地提升了其工作性能。
In order to improve the real-time characteristic and network load balance in a IPv4 networked measuring and controlling platform, a new generation network IPv6 is introduced to measuring and controlling platform and a new strategy of IPv6 operating mode （anycast mode） in measuring and controlling network is emphatically studied. How to use the IPv6 anycast mode to improve the performance of the platform is discussed. By syncretizing the mathematic model of anycast mode and reasoning the strategy with D-S evidence theory, the experiment environment is simulated accurately by combining the network software OPNET with industry scene situation. The experimental results show that the network time delay of the IPv6 is reduced from 0. 512 ms to 0. 295 ms compared with IPv4 original mode and the performance is greatly improved, which shows the introduced method provides an approach to studying the new generation measuring and controlling network.
