Embodiment Construction

[0094] During the process of the invention, the inventors noticed:

[0095] The existing transparent transmission processing technical solutions are generally implemented by encapsulating an additional layer of VLAN on the outer layer of the service VLAN before the data frame is sent to the server on the vSwitch and SR-IOV to form a QinQ (802.1Q-in-802.1Q) data frame. VLAN transparent transmission. image 3 It is a schematic diagram of VLAN transparent transmission. The specific scheme is as follows image 3 shown.

[0096] When the data frame sent by the virtual port has “service VLAN”—Q1, the vSwitch or SR-IOV network card encapsulates it with an additional layer of isolation VLAN—Q2, which becomes a QinQ data frame. The encapsulated Q2 is fixed and all virtual network. ID, and inbound traffic is processed in reverse.

[0097] To correctly transparently transmit QinQ data frames, you need to configure the QinQ data frame transparent transmission policy on the access switc...

Abstract

The invention discloses a data frame transmission method, a virtualization platform and a storage medium. The data frame transmission method comprises the steps that a virtual machine platform receives a data frame which is sent by a virtual machine from a virtual port and carries VLAN information; converting the VLAN information in the data frame into a corresponding VLAN head according to the configuration table; and sending the data frame carrying the VLAN head to the switch. The virtual machine platform receives a data frame which is sent by the switch and carries a VLAN head; converting the VLAN head in the data frame into corresponding VLAN information according to the configuration table; a data frame carrying the VLAN information is sent to a virtual port of the virtual machine, and the configuration table comprises the corresponding relation between the VLAN information and the VLAN head. By adopting the method and the device, the transformation requirement on the upper layer service is avoided, the unvarnished transmission scheme of the data frame is simpler, the configuration process is simpler, and the automatic network opening in the service full life cycle process can be realized.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and in particular, to a data frame transmission method, a virtualization platform and a storage medium. Background technique [0002] Virtualized network elements usually use VLANs (Virtual Local Area Network) to identify their own service interfaces, such as different VLANs to distinguish network planes (such as management plane and service plane), and distinguish service exports (such as going to CMNET (China Mobile Internet, China Mobile Internet) Mobile Network), IP bearer network, etc.), distinguish interfaces between network elements (such as distinguish S-GW (Serving Gateway, Serving Gateway) / P-GW (PDN Gateway, PDN Gateway; PDN: Packet Data Network, Packet Data Network) interface Interface with S-GW / MME (Mobility Management Entity, Mobility Management Entity) and so on. In a virtualized environment, the appearance of this service feature is that the data frame sent ...
