Research on Service Controlling Algorithm of Electric Power Communication Network based on QoS Traffic Recognition and Routing Optimization

摘要

With rapid progress in power communication networking, the present power communication network has become an integrated transmission network that supports various services (e.g., control data, service data, voices, and images). Compared with traditional network services, real-time services in the present power communication network have stricter requirements on delays, delay jitters, and packet losses. QoS techniques can guarantee the network service qualities overall, provide different QoS for different power communication network services, and improve network resource utilization, as well as satisfying the requirements of key services (e.g., relay protection and power dispatching). After analyzing the problems and challenges facing the QoS routing of the present power communication network, a QoS routing module is proposed under the service classification system. The most prominent feature of the proposed model is its ability to match different network services with suitable QoS. Our model consists of the service recognition and classification module, the routing module, and the client service analysis module. In the system tests, the proposed method for classifying power communication network services is used to implement the routing model under the service classification system. At the client end, the service types of the data are statistically analyzed, and service type maps are plotted. The statistical analysis shows that the proposed model has excellent QoS performance.
