Abstract

The present application discloses a method for upgrading a virtual switch, including: loading an intermediate switching unit in the virtual switch; reading the configuration information of the first switching unit of the virtual switch, and writing it into the intermediate switching unit; The switching channel of the first switching unit is switched from the first switching unit to the intermediate switching unit; a second switching unit for upgrading the first switching unit is loaded in the virtual switch, and the configuration information is written into the A second switching unit; switching the switching channel of the data message from the intermediate switching unit to the second switching unit. Based on this method, during the upgrade process of switching from the first switching unit to the second switching unit, the disconnection time is relatively short, thereby reducing the number of data packet loss caused by network disconnection, and reducing the number of data packets lost due to network disconnection. caused losses.

Description

technical field [0001] The present application relates to the technical field of virtualization, in particular to a method for upgrading a virtual switch. The present application also relates to an upgrade device for a virtual switch. Background technique [0002] A virtual switch (vSwitch, Virtual Switch) refers to the use of a virtual platform to form a switch component through software. The virtual switch works in a layer-2 data network, and realizes the layer-2 (and part of layer-3) network functions of a physical switch through software. Compared with traditional physical switches, virtual switches have many advantages. One is flexible configuration and strong scalability. An ordinary server can be configured with dozens or even hundreds of virtual switches, and the virtual port (vPort) of the virtual switch The number of virtual switches can be flexibly set; second, the cost is lower and the performance is higher, and the virtual switch can often achieve the performan...
