Private network access method and system based on virtual switches and SDN (Software Defined Network) technology

Abstract

The application discloses a private network access method and system based on virtual switches and SDN technology. The method comprises the steps of: dividing a physical server into a network node and a computing node; establishing a plurality of virtual switches on the network node; establishing a private network and allocating a virtual local area network in a corresponding computing node, so as to bind a port for connecting a second-layer switch and the computing node to the virtual local area network; setting the virtual local area network for a second virtual switch; setting a network mode of a tenant as a virtual extensible local area network; and allocating a network identifier, which is related to the virtual local area network, of the virtual extensible local area network of another virtual switch, so that the computing node and the network identifier communicates corresponding to a host or a virtual machine. The method conveniently separates different physical servers rented by different tenants, reduces the dependence to a physical hardware equipment for adding a bare metal physical server into the software defined network, and is unnecessary to use a programmable switch.

Description

technical field [0001] The present invention relates to the field of SDN (Software Defined Network, software defined network) network technology, in particular to a private network access method and system based on a virtual switch and SDN technology. Background technique [0002] At present, most SDN technologies only support virtual machines or host machines deployed with virtualized operating systems. However, many applications or platforms need to be directly deployed on physical servers, such as high-performance computing clusters, computing tasks that need to access hardware devices that cannot be virtualized, and database hosts (some databases run poorly in hypervisors, and hypervisors are a The intermediate software layer between the physical server and the operating system allows multiple operating systems and applications to share a set of basic physical hardware, so it can also be regarded as a "meta" operating system in a virtual environment, which can coordinate...
