A network construction method for multi-cloud environment based on software-defined network

Abstract

The invention discloses a multi-cloud environment network construction method based on a software-defined network. The method comprises the following steps: 1) for each selected cloud platform, building a software-defined network on the cloud platform; 2) selecting a server serving as an external open interface on each cloud platform, that is, an external interface server; 3) using the external interface server for interconnecting the virtual networks on the cloud platform, so as to realize the interconnection of the virtual networks of different cloud platforms; 4) the software-defined network management node is deployed on each external interface server, a multi-cloud environment network is constructed, and the virtual networks under the multi-cloud environment network are managed. According to the method, a multi-cloud environment network is constructed and the virtual networks under the multi-cloud environment network are managed. The cloud platform virtual machine and the container network configuration information can be quickly inquired, so that cross-cloud construction and management of virtual machines and containers are achieved, and service cross-cloud deployment is guaranteed.

Description

technical field

[0001] The invention relates to the technical field of computer software, in particular to an SDN-based cross-cloud network construction method. Background technique

[0002] Software Defined Network (Software Defined Network, SDN) is a new type of network architecture and a way to realize network virtualization. Its core technology, OpenFlow, realizes network The flexible control of traffic makes the network more intelligent as a pipeline.

[0003] A multi-cloud environment is a business environment based on a new IT infrastructure. The traditional IT infrastructure is based on a pure physical architecture, which has low scalability and high deployment and maintenance costs. The new IT infrastructure is gradually migrating to the virtual environment and cloud environment. Through the hybrid interaction of the virtual machine environment and the cloud environment, the development, testing and deployment of applications in multiple cloud environments are rea...
