Research on the Application of an Overlay Network Distributed Transmission Technology in the Municipal Regulatory System

With the growing popularity of the Internet and the rapid growth of bandwidth, multimedia video transmission has become one of the main trends of the Internet´s current and future business development. However, it is more and more difficult for the current Internet network layer and transport layer services to meet the diverse needs of end-to-end transmission performance of the multimedia video services. The paper studies the core network on which national or provincial-level municipal comprehensive monitoring system relies and network congestion in large-scale regulatory data aggregation and distribution. Based on overlay routing and multi-routing load balancing technology, the study breaks through the network routing limitations of IP core network and builds a multi-point dynamic distributed information transmission structure between data servers. Under the premise of not changing the basic routing network switching equipment and protocols of the core IP network, it realizes high-quality end-to-end interactive transmission of multimedia information by upgrading transmission software module at the data server, furthers the multicast transmission service quality of the IP core network and enhances the robustness and QoS of the core network of the regulatory system.
