Embodiment Construction

[0043] In view of the above-mentioned problems existing in the prior art, the embodiment of the present invention provides a method for establishing a link between a vSwitch and a pSwitch and its system, and addresses the different situations of whether the virtual server system has an interface description on the side of the link with the physical switch , solutions are provided respectively.

[0044] Embodiments of the present invention are described below in conjunction with the accompanying drawings, wherein image 3 Describes the flow of link calculation between vSwitch and pSwitch when there is an interface description on the link side of the physical switch in the virtual server system, Figure 4 Describes the flow of link calculation between vSwitch and pSwitch when there is no interface description on the link side of the physical switch in the virtual server system.

[0045] see image 3 , this embodiment describes the process of establishing a link between vSwitch...

Abstract

The invention discloses a link establishment method for a virtual switch and a physical switch and a device thereof. The method comprises the following steps of: when interface description information from a virtual server system to an external link is configured, searching virtual network card information according to the interface description information and searching corresponding virtual switch information according to the searched virtual network card information by a virtual server management system; establishing a link between the corresponding virtual switch and the physical switch according to the searched virtual switch information; when the interface description information from the virtual server system to the external link is not configured, acquiring a virtual network card IP address of the virtual server system and judging whether the acquired virtual network card IP address is a management IP address by the virtual server management system, if so, acquiring the virtualswitch information corresponding to the virtual network card; and establishing the link between the corresponding virtual switch and the physical switch according to the searched virtual switch information.

Description

technical field [0001] The invention relates to the communication field, in particular to a link establishment method and device for a virtual switch and a physical switch. Background technique [0002] Virtualization technology is a technology that virtualizes physical resources. At present, the main virtual physical resource is the host computer. Because it can fully improve resource utilization, be environmentally friendly, and reduce space occupation, virtualization applications are becoming more and more extensive. [0003] Virtual Server (Virtual Server) uses special software and hardware technology to divide a real physical host into multiple logical units (ie, virtual servers). Each unit has no physical entity, but each unit can resemble a real server. It works on the network like a physical host, with a separate domain name, IP address (or shared IP address), and complete Internet server functions. The virtual servers are completely independent from each other, and...
