Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0042] see figure 1 , the present invention proposes a software-defined network-based user autonomous routing customization system, the system includes the following functional modules:

[0043] Network topology information detection module: this module is responsible for the detection of network topology information. The network topology mainly refers to the topology structure of the relative logical positions between switches, that is, the topology structure is logical, not physical; The network topology information is detected by the SDN controller and reported to the application program; because the network topology information is dynamically changing, the SDN controller sends a detection packet to the responsible switch at regular intervals to determine the v...

Abstract

Provided is a user autonomous routing customization system based on a software-defined network. The system comprises a network topology information detection module, a network performance detection module, a network resource integration module, a network resource presenting module, a network key point extraction module, a user key point selection module, a route computation module and a user interaction interface module. Also provided is a user autonomous routing customization method based on the software-defined network. The method comprises the following operation steps that (2) a user logs in a system and views current network resource information; (2) the system recommends candidate routing schemes to the user; (3) the user selects one routing; and (4) strategy customization and resource scheduling are performed on a physical network by the system so that customized control of the network is actively performed by the user. An objective that the user autonomously selects the customized routing schemes is realized by the system and method.

Description

technical field [0001] The invention relates to a software-defined network-based user autonomous routing customization system and method, belonging to the technical field of the Internet, in particular to the technical field of software-defined networks. Background technique [0002] The Internet has become an indispensable part of people's life, and the rich resources and various applications on the Internet have greatly changed people's way of life. This makes it very difficult for researchers to study new network architectures and control services, which affects the scalability of the network and hinders the development of new network technologies. Under the strong pressure, the modern Internet has shown urgent problems such as low security, complex network control, low data forwarding efficiency, and shortage of network addresses. The root of all these problems can be attributed to the lack of effective controllable Internet sex. [0003] As the support of various appl...
