Problems solved by technology

[0005] However, in the existing technology, since the physical device is connected to the virtual gateway based on the layer-3 network protocol, it is difficult to set the physical device and the virtual machine in the virtual network in the same subnet, which makes it difficult to migrate the virtual machine to the physical device.
It is also difficult to maintain a completely consistent user experience on virtual machines and physical devices, and it is difficult to realize virtualized services seamlessly supporting physical device access

Embodiment Construction

[0030] A detailed description will be given below of embodiments of the present invention. Although the present invention will be described and illustrated in conjunction with some specific embodiments, it should be noted that the present invention is not limited to these embodiments. On the contrary, any modification or equivalent replacement made to the present invention shall be included in the scope of the claims of the present invention.

[0031] Some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe operations as sequential processing, many of the operations may be performed in parallel, concurrently, or simultaneously. In addition, the order of operations can be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not included in the figure. The processing may correspond to a method, function, procedure, subroutine, subroutine, or the like.

Abstract

The invention provides a communication method, a device and a system used for a physical device and a virtual network. The method comprises the following steps that a NVGRE gateway receives a first request data packet from the physical device through a two-layer switch, and a target IP address of the first request data packet is an IP address of a virtual machine in the virtual network; the NVGRE gateway carries out network-virtualization general route packaging on the first request data packet so as to acquire a first packaging data packet including the first request data packet; and the NVGRE gateway forwards the first packaging data packet to the virtual network. The physical device is connected to the virtual gateway based on a second layer network protocol so as to increase connection performance and a user experience degree.

Description

technical field [0001] The invention relates to network virtualization technology, in particular to a communication method, device and system for physical devices and virtual networks. Background technique [0002] Just as server virtualization (hypervisor) can provide a "virtual machine" for the operating system, network virtualization decouples the virtual network from the physical network infrastructure, thereby solving problems such as the limitation of hierarchical IP address allocation for virtual machine configuration. [0003] However, how to communicate from the physical network to the virtual network has become a new topic. [0004] In the prior art, Microsoft Corporation provides a Hyper-V Network Virtualization Gateway (Hyper-V Network Virtualization Gateway) for bridging a physical device and a network virtualization environment. Specifically, physical devices are connected to routers based on Layer 3 network protocols, and are connected to network virtualizati...
