Problems solved by technology

But once there are too many rules on the forwarding plane, it will take a while to upgrade, during which time all existing traffic will be lost
This will affect the user experience, and usually can only be operated in the early morning when the user traffic is low

Abstract

The present invention provides a method, device, storage medium and equipment for updating a virtual switch. The method includes: sending the forwarding rules of the virtual machine for data exchange with the virtual switch from the virtual switch to the virtual network card of the virtual machine and communicating with the virtual The physical network card corresponding to the machine; establish the data transmission link between the virtual network card and the physical network card, so that the virtual network card and the physical network card directly forward the data of the virtual machine through the data transmission link according to the forwarding rules; update the virtual switch.

Description

Method, apparatus, storage medium and device for updating virtual switch technical field The present invention relates to the field of virtual switches, and in particular to a method, device, and storage medium for updating a virtual switch. quality and equipment. Background technique In the environment of cloud computing, Virtual Switch (virtual switch) provides efficient virtual Network packet forwarding. A virtual switch is usually divided into a control plane and a data forwarding plane. The control plane issues forwarding rules (flow table) to the data plane, and the real forwarding behavior occurs on the data plane. Due to the importance of the data plane, the data plane design is usually more More concise, try to avoid restarting. [0003] The current upgrade of the data plane mainly relies on some user-mode hot patches. There is also a machine for fast restart of the data plane system. But existing scheme has following deficiency: [0005] For the user...
