Embodiment 1
[0137] Based on the simulation parameters in Table 1, this embodiment simulates a multipath-based software-defined network implementation method in the present invention, and the performance analysis is as follows: when the network data transmission volume is small, the success rate of the device obtaining data is high, when When the amount of network data transmission is large, the success rate of equipment to obtain data is slightly reduced; the average success rate of network to obtain data is 99.5%.

The invention provides a software-defined network implementation method based on multipath. The network comprises a core controller, two or more local controllers, a switch and a device. The local controller is used for managing the switch, the core controller is used for managing the local controller, and the device is the terminal device. The devices communicate through the switch; The network can quickly acquire network data, shorten routing delay, reduce data packet loss rate and improve service quality through the realization method provided by the invention. The invention can be appliedto the fields of road condition monitoring, environment monitoring and the like, and has a wide application prospect.
Description
technical field [0001] The present invention relates to an implementation method, in particular to a multipath-based software-defined network implementation method. Background technique [0002] As a new type of communication network, software-defined network can realize multi-hop wireless communication between nodes. With the continuous development of network technology and the continuous emergence of various new applications, there is an urgent need to improve network performance. [0003] At present, researchers have proposed a mode of obtaining network services through software-defined networks and defined the corresponding protocol stack, but because the architecture of software-defined networks is different from that of traditional networks, the existing methods of network service acquisition have some limitations sex. Therefore, it is necessary to propose a low-latency software-defined network implementation method to improve service quality. Contents of the inven...
