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 invention provides a method and a device for updating a virtual switch, a storage medium and equipment. The method comprises the following steps: respectively sending a forwarding rule of a virtual machine which exchanges data with the virtual switch to a virtual network card of the virtual machine and a physical network card corresponding to the virtual machine from the virtual switch; establishing a 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 data of the virtual machine through the data transmission link according to a forwarding rule; updating virtual switches.

Description

technical field [0001] The invention relates to the field of virtual switches, in particular to a method, device, storage medium and equipment for updating a virtual switch. Background technique [0002] In the environment of cloud computing, Virtual Switch (virtual switch) provides efficient virtual network packet forwarding for each virtual machine. A virtual switch is usually divided into a control plane and a data forwarding plane. The control plane sends forwarding rules (flow tables) to the data plane, and the real forwarding behavior takes place on the data plane. Due to the importance of the data plane, the design of the data plane is usually relatively simple, and restarts should be avoided as much as possible. [0003] The current upgrade of the data plane mainly relies on some user-mode hot patches. There are also mechanisms for fast restart of the data plane. [0004] However, existing solutions have the following disadvantages: [0005] For the user-mode hot...
