NODE DEVICE, COMMUNICATION SYSTEM, AND METHOD FOR SWITCHING VIRTUAL SWITCH

摘要

When a failure occurs in a virtual machine (hereinafter called “VM”), degenerate operation not routed through the VM which is a failure target, and corresponding to a communication service on the VM is conducted to shorten a communication interrupt time. A communication path of a virtual switch in a multitenant environment where a virtual machine that operates a plurality of software provides a communication service for cloud computing such as a WAN high-speed technology is controlled. The control method, for example, comprises the steps of monitoring an operating status of the communication service of the virtual machine, and conducting a communication control by changing the communication path and a communication method of the virtual machine according to an application of the communication service if a failure occurs in the application of the communication service of one virtual machine.

主权项

1. A node device, comprising:
a virtual machine that executes a given application to provide a communication service; an interface unit that transmits and receives communication data; a virtual switch unit that transfers the communication data between the virtual machine and the interface unit; and a control unit that controls a communication path through the virtual switch unit between the interface unit and the virtual machine, wherein the control unit monitors an operating state of the communication service of the virtual machine, and controls the virtual switch unit to change a communication path and/or a communication method of the communication data according to failure dealing information corresponding to the communication service when detecting a failure related to the provision of the communication service by the virtual machine.
