Embodiment 1

[0042] According to an embodiment of the present invention, an embodiment of an SDN-based network data transmission method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings may be executed in a computer system such as a set of computer-executable instructions. and, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that herein.

[0043] The method embodiment provided in Embodiment 1 of the present application may be executed in a mobile terminal, a computer terminal, or a similar computing device. figure 1 It is a hardware structural block diagram of a computer terminal (or mobile device) of an SDN-based network data transmission method according to an embodiment of the present invention. like figure 1 As shown, the computer terminal 10 (or mobile device 10 ) may include one or more (shown as 102a, 102b, . A processing device such as a pro...

Embodiment 2

[0121] The preferred implementation of the above method in this embodiment will be further introduced below, and a method for NFV access based on an elastic gateway based on a network card in an SDN network will be specifically described as an example.

[0122] Currently, NFV is deployed in ECS. Generally, NFV instances and client instances can communicate with each other through the solution of elastic network cards. However, this solution has the following problems: limited by the implementation of elastic network cards, dependent on resources on computing nodes, and the number of elastic network cards. Restricted; in some scenarios, NFV implements the capabilities of the infrastructure service layer network and directly communicates with the infrastructure service layer, and the current NFV access cannot implement this scenario.

[0123] To solve the above problems, the present application provides a multi-tenant solution, Figure 5 is a schematic diagram of interworking be...

Abstract

The invention discloses an SDN-based network data transmission method, an access method and a storage medium. The method comprises the following steps: controlling a first elastic network card for transmitting data to access a software defined network (SDN); determining a gateway associated with the first elastic network card in a software defined network (SDN), the elastic network card information of the first elastic network card being configured on the gateway; first configuration information between the gateway and a virtual private cloud VPC system is obtained, and the first configuration information is used for representing that data transmission is allowed between the gateway and the VPC system; and transmitting data associated with the first elastic network card between the gateway and the VPC system based on the first configuration information. According to the invention, the technical problem of low data transmission efficiency is solved.

Description

technical field [0001] The present invention relates to the field of computers, and in particular, to an SDN-based network data transmission method, an access method and a storage medium. Background technique [0002] At present, in the allocation and processing of resources, Network Functions Virtualization (NFV) is usually deployed in the Elastic Cloud Server (ECS), because the elastic network card usually depends on the computing node. Therefore, limited by the resources on the node, the number of elastic network cards is limited. At the same time, this method cannot realize the intercommunication between the elastic network card and the VPC network, and there is a technical problem of low data transmission efficiency. [0003] For the above problems, no effective solution has been proposed yet. SUMMARY OF THE INVENTION [0004] Embodiments of the present invention provide an SDN-based network data transmission method, access method, and storage medium, so as to at lea...
