Embodiment Construction

[0043] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0044] An example of the present invention is figure 2 shown.

[0045] The mobile device is an android phone, and at least one application that needs to access the Internet is installed in the mobile device.

[0046] A POP is a point of presence (POP). Generally, the closer the POP is, the smaller the line signal loss is, and the higher the bandwidth guarantee can be provided for the connected users.

[0047]SD-WAN is based on the POP networking mode. The POP points are not based on the internet networking, but are interconnected using MPLS-VPN or other dedicated lines. Mobile devices usually need to be connected to the nearest POP point through the Internet, that is, the "last mile" is a network connected by the Internet.

Abstract

The present invention provides a method, POP and system for a mobile device to access an SD-WAN network. The present invention belongs to network communication technology, especially SD-WAN networking technology. The present invention is used to solve the problem of mobile devices accessing an SD-WAN network. question. The method of the present invention includes: creating a virtual network interface device on behalf of the client, and setting the traffic of the first application program to be forwarded by the virtual network interface device; the proxy client reads the virtual network interface device through the file descriptor Write the virtual network interface device, thereby acting as a proxy for the data packet sent by the first application program; the proxy server receives the data packet sent by the proxy client, and the proxy server receives the data packet corresponding to the TCP long connection account, and mark the corresponding first mark on the data packet; thus, the system tool on the first POP can count the upstream traffic of the account according to the first mark, and determine the corresponding value of the upstream traffic according to the statistical value and threshold of the upstream traffic. Packet forwarding and discarding.

Description

technical field [0001] The invention belongs to network communication technology, especially SD-WAN networking technology. Background technique [0002] SD-WAN, that is, software-defined wide area network, is a service formed by applying SDN technology to wide area network scenarios. This service is used to connect enterprise networks, data centers, Internet applications and cloud services in a wide geographical range. Through SD- WAN technology, users can get a better network experience. [0003] The world is actively exploring the application demand scenarios of SDN technology. The mainstream demand scenarios that have emerged include data center virtualization, WAN traffic optimization, mobile backhaul network IP RAN, IP access network / MAN, transport network, business Chain and service routing, IP+optical collaborative networking, network security, etc. [0004] However, due to the difficulty of early research and development of SD-WAN and the high cost of deployment, t...
