Embodiment 1
[0044] like figure 1 As shown, the SDN-based power distribution Internet of Things network architecture of this embodiment separates the data plane from the control plane, so as to simplify the realization of network management and configuration functions, and provide a flexible routing selection method. On the data plane, the sensor terminals of the power distribution Internet of Things are distributed in various application scenarios of the power distribution Internet of Things, continuously collect the operating data and environmental information of the power distribution Internet of Things equipment, and transmit such business data through the access network in a wired or wireless manner. transmitted to the data forwarding layer. In the data forwarding layer, there are routing relay nodes connected with each other in various topological forms. The collected data is transmitted to the data aggregation node through these routes through one or more hops, and is further proces...
Embodiment 2
[0054] like image 3 As shown, this implementation example discloses an SDN-based routing selection method for power distribution Internet of Things based on the above model. SDN technology is used to separate the data plane and control plane of power distribution Internet of Things to simplify the realization of network management and configuration functions, and provide flexible Routing selection, and based on a reinforcement learning algorithm called SARSA algorithm, it solves the routing selection problem during data forwarding of power distribution Internet of Things business.
[0055] first, look again figure 1 As shown, based on SDN technology, the architecture of power distribution Internet of Things is established, the reward model of data forwarding delay and packet loss of different priority services is established, and the optimization problem with the goal of maximizing reward is constructed. Then, through the SARSA algorithm, the SDN controller, as an agent in r...
Embodiment 3
[0091] The purpose of this embodiment is to provide an SDN-based power distribution Internet of Things routing system, including:
[0092] The model building module is configured to: establish a power distribution Internet of Things architecture based on SDN, and establish a power distribution Internet of Things network model based on the architecture;
