Embodiment Construction

[0030] The virtual machine network is an operating environment used to carry complex networked applications. It is characterized by providing flexible allocation, controllable resources, and isolated operating environments for applications. Virtual machine networking needs to be pre-deployed. In the application scenario of the virtual machine network, the creation and destruction of the virtual machine network occurs dynamically, while the underlying host usually does not change. The deployment of the virtual machine network is to install and configure the dynamically generated virtual machine network on the bottom layer. on the host machine. Specifically, the deployment of the virtual machine network may include virtual machine deployment, virtual switch deployment, and virtual router deployment. figure 2 It is a schematic diagram of deployment of the virtual machine network of the present invention, such as figure 2 As shown, virtual machines A, C, E, and H are deployed ...

Abstract

The invention discloses a method, a device, a system and a host for three-layer switching. The method comprises the following steps of: receiving a network message sent by a source virtual machine; according to three-layer switching information acquired in advance, carrying out the three-layer switching treatment of the network message, and generating the network message undergoing the three-layer switching treatment, a virtual link of a destination virtual machine and a three-layer destination address of the destination virtual machine; and according to the three-layer destination address of the destination virtual machine, sending the network message undergoing the three-layer switching treatment to the destination virtual machine by the virtual link of the destination virtual machine. In the technical proposal, the host completes the three-layer switching treatment of the network message according to the three-layer switching information acquired in advance, and sends the network message undergoing the three-layer switching treatment to the destination virtual machine according to the three-layer destination address of the destination virtual machine, so that the three-layer switching efficiency of a virtual machine network is effectively improved.

Description

technical field [0001] The invention relates to the technical field of virtual machines, in particular to a three-layer switching method, device, system and host machine. Background technique [0002] Virtual machine technology is to install software to run in a virtual machine, which can realize rapid software deployment, fine-grained computing resource allocation and load balancing scheduling, and provide a highly available software fault-tolerant mechanism. At present, virtual machine technology has been gradually applied by enterprises. The use of virtual machine technology can effectively reduce the complexity of IT management, save management costs, and improve the utilization of computing resources. With the deepening of computer applications, the scale of software is getting bigger and bigger, and the functions are becoming more and more complex. The operating environment of the software is no longer limited to the stand-alone environment, but has gradually evolved i...
