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%.

Abstract

The present invention provides a method for realizing a software-defined network based on multi-path. The network includes a core controller, more than two local controllers, switches and devices; the local controller is used to manage switches, and the core controller is used to manage local The controller, the device is the terminal device; the device communicates through the switch; the network can quickly obtain network data through the implementation method provided by the present invention, shorten the routing delay, reduce the data packet loss rate, and improve the service quality. The present invention can be applied to Road condition monitoring, environmental monitoring and other fields have broad application prospects.

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...
