Abstract

The invention discloses an SDN (Software Defined Network) implementation method. An SDN controller receives virtual network information transmitted by a cloud computing platform, and the virtual network information comprises the corresponding relation between VM information and information of a server for operating a VM. The SDN controller obtains physical network information, and the physical network information comprises the corresponding relation between the information of a TOR switcher and the information of the server. The SDN controller obtains the corresponding relation between the information of the VM and the information of the TOR switcher according to virtual network information and the physical network information. Therefore, the method can build a physical transfer path for the VM in a physical network, achieves the mapping from the virtual network to the physical network, and better supports the cloud computing platform to carry out the automatic distribution and adjustment of the businesses of the SDN controller as required.

Description

Technical field [0001] The present invention relates to the field of network technology, in particular to a method, device and system for implementing a software-defined network SDN. Background technique [0002] The cloud computing platform OpenStack is an open source Infrastructure as a Service (IaaS) cloud computing platform that allows anyone to build and provide cloud computing services by themselves. OpenStack is composed of multiple relatively independent service components, such as: Compute (Nova): virtual machine management component, used for virtual machine computing or using groups to start virtual machine instances, Compute is an OpenStack computing node, also known as Nova component; Networking (Neutron): Network management component, which provides virtual network functions in the cloud computing environment. Openstck can send virtual network management and control information to the SDN controller Controller through Neutron API to realize virtual network slicing a...
