Abstract

The invention relates to virtual network equipment, a virtual overlay network and a configuration and message transmission method, and the virtual network equipment comprises a Vth end which is used for plugging a virtual machine / container and providing a virtual network card for the virtual machine / container; and the tun end is arranged in the linux system kernel, serves as a virtual tunnel configuration interface of the linux system kernel, configures the type of the virtual tunnel according to the received virtual tunnel type configuration information, and configures the identifier of the virtual tunnel according to the virtual tunnel identifier configuration information. The virtual overlay network constructed by the virtual network equipment provided by the invention does not depend on a third-party virtual switch OpenvSwitch, so that the forwarding performance of data traffic is effectively ensured. Therefore, when a plurality of tenants exist and the VPC network addresses of the plurality of tenants are overlapped, forwarding can also be performed based on the tun identifier, and the difficulty and workload of network configuration and network maintenance are reduced.

Description

technical field [0001] The application relates to a virtual network device, a virtual overlay network and its configuration, and a message transmission method, and belongs to the field of network technology. Background technique [0002] In SDN (Software Defined Network), the overlay network breaks the limitation of physical addresses by superimposing the virtualization technology mode on the traditional network architecture, and realizes the application carrying on the network without large-scale modification of the basic network. , and separate applications from other network services, which greatly facilitates the migration of virtualized services such as virtual machines and containers in the data center. [0003] OVS (OpenvSwitch), as a high-quality, multi-layer, scalable virtual switch, plays an important role in SDN. Managers can use OVS to complete various tunnel establishment and service orchestration. However, in actual production, we found that the performance o...
