Problems solved by technology
[0003] At present, the construction of my country's power distribution communication network is backward, and the construction of various places is uneven. There is no unified construction specification. Most of them use the form of renting public networks. The power distribution facilities are located in the basement or covered by forests, etc., and there are blind spots. sexual demands
However, the traditional IP network architecture cannot well meet the needs of power distribution services

Embodiment Construction
[0027] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0028] figure 1 It is a schematic diagram of the heterogeneous power distribution communication network architecture of the present invention. The network architecture refers to the core idea of separation of control information and data in "Software Defined Network" (Software Defined Network, SDN), and adds an SDN controller to the network. Through The SDN controller monitors the network status and controls routing and forwarding. The network architecture consists of SDN controllers, core network routers, dual-mode terminals, LTE base stations, WiMax base stations, WLAN AP (Access Point) nodes, and short-distance wireless (433MHz, 470MHz, 780MHz) AP nodes. Including three-layer network architecture: application layer, power distribution business transmission layer, power distribution business collection layer. The network architecture...

The present invention relates to a heterogeneous distribution communication network architecture based on a software defined network, belonging to the technical field of power grid communication. The heterogeneous distribution communication network architecture is characterized in that the idea that control information is separated from data in the software defined network is used for reference, a controller is added to a distribution communication network, a terminal access and switching process can be effectively simplified through the controller, IP remains unchanged after a terminal accesses the network, so that switching time at an IP layer can be reduced during switching of the special-shaped distribution communication network, thereby shortening network delay. The controller achieves seamless switching between routing forwarding and a wireless network, thereby improving the whole network load balance condition, and reducing network congestion. The heterogeneous distribution communication network architecture provides a feasible solution for effectively solving the problems of a coverage blindness area of the distribution communication network, convergence between a plurality of services and a heterogeneous network, and seamless switching of the heterogeneous network.
Description
technical field [0001] The invention belongs to the technical field of power grid communication, relates to a network architecture applied in a power distribution communication system, and in particular to a software-defined network-based heterogeneous power distribution communication network architecture. Background technique [0002] With the development of smart distribution network, the data volume of power distribution business is increasing, the amount of monitoring information on the power distribution side is huge, the power distribution business is scattered, and the communication environment is complex and changeable. Wireless communication is the best choice to solve the "last mile" on the power distribution side. There are many kinds of power distribution business. According to the communication requirements of different business data, different wireless communication methods are used to flexibly network, and building an efficient, reliable and economical power d...
