A software-defined network-based open virtual network construction system and method

Abstract

The invention discloses a virtual open network building system based on a software definition network. The virtual open network building system comprises a network topological information detection module, a network performance detection module, a network resource integration module, a network resource display module, a user virtual node selection module, a virtual network management module, a network resource virtualization module, a host unit resource virtualization module and a user interaction interface module. A virtual open network building method based on the software definition network comprises the steps that (1) a user logs into the virtual open network building system; (2) the system collects network resource information and visually displays the information to the user; (3) the user finds resources for specific service and provides a service request; and (4) the system provides virtual network customization service for the user. According to the virtual open network building system and the virtual open network building method, the aim of the user for opening and self-building a virtual network is achieved.

Description

technical field [0001] The invention relates to a software-defined network-based open virtual network construction system and method, belonging to the technical field of the Internet, in particular to the technical field of software-defined networks. Background technique [0002] Network virtualization is an emerging network technology. It abstracts the shared underlying infrastructure (Infrastructure) through virtualization technology and provides a unified programmable interface. It virtualizes infrastructure construction through virtual resource slicing or tunneling. Build multiple isolated and heterogeneous virtual networks on top of the existing infrastructure to provide users with differentiated services. Virtual networks can be simply isolated on the edge network through existing virtual local area network (Virtual Local Area Network, VLAN), virtual private network (Virtual Private Networks, VPN) and other technologies, and data transmission on the public Internet sti...

Problems solved by technology

Virtual networks can be simply isolated on the edge network through existing virtual local area network (Virtual Local Area Network, VLAN), virtual private network (Virtual Private Networks, VPN) and other technologies, and data transmission on the public Internet still relies on best-effort At the same time, these operations are only supported by the basic network administrator, the process is cumbersome and the function of virtual network construction is limited, which is not enough to meet the diverse needs of multi-user flexible network construction
