Problems solved by technology

On the other hand, existing research reports show that in areas with dense Wi-Fi networks in China, there are more than 10 Wi-Fi hotspots nearby for connection in more than 50% of cases, but about 60% of them have Wi-Fi hotspots. The transmission speed of the network bandwidth is less than 1Mbit / s

Embodiment 1

[0025] figure 1 A flowchart of the method for uploading online live broadcast based on edge network aggregation provided in Embodiment 1 of the present invention is shown. For convenience of description, only the parts related to the embodiment of the present invention are shown, and the details are as follows:

[0026] A1: The data source client transmits the video to the network aggregation terminal, and the network aggregation terminal sends a request to the scheduling server to connect to an optimal aggregation server;

[0027] As an optional implementation manner, the network aggregation terminal may be a device with multiple network interfaces and a built-in lightweight linux operating system such as OpenWrt, which can provide a Wi-Fi hotspot. During specific implementation, the network aggregation terminal needs to have multiple network cards, including an LTE wireless network card and a Wi-Fi access wireless network card. The Wi-Fi access wireless network card can be ...

Embodiment 2

[0056] figure 2 A schematic diagram of the online live uploading system based on edge network aggregation provided by Embodiment 2 of the present invention is shown. For the convenience of description, only the parts related to the embodiment of the present invention are shown, and the details are as follows:

[0057]The online live uploading system based on edge network aggregation according to the embodiment of the present invention includes a data source client, a network aggregation terminal, a scheduling server, an aggregation server, an original server, and a data receiving terminal. The data source client can be an intelligent terminal with video recording and wireless transmission functions, such as a mobile phone. The data source client transmits the data to the network aggregation terminal by wire or wirelessly such as Wi-Fi through TCP connection. The network aggregation terminal communicates with the scheduling server through TCP connection, such as sending a req...

Abstract

The invention belongs to the field of network communication, and proposes an online live upload method and system based on edge network aggregation, which can transmit the video of the data source client to the network aggregation terminal, and the network aggregation terminal sends a request to the scheduling server; the scheduling The server allocates an optimal aggregation server for the network aggregation terminal according to the feedback information of the network aggregation terminal and the original server, network bandwidth measurement, etc.; the network aggregation terminal transmits the video through at least one Wi‑Fi and / or at least one LTE network link to the optimal aggregation server; the optimal aggregation server transmits the video to the original server, and then the original server distributes the video to each data receiving end. Through the embodiment of the present invention, a large amount of data is transmitted using multiple small-bandwidth edge networks, that is, bandwidth aggregation of the edge network is realized, and scheduling is performed according to different network link states to maximize the uplink bandwidth.

Description

technical field [0001] The invention belongs to the field of network communication, and in particular relates to an online live uploading method and system based on edge network aggregation. Background technique [0002] In the existing online live broadcast platforms and frameworks, on the one hand, the optimization is mainly for the process of distributing the video from the server or CDN to the audience, but not for the process of uploading the video to the server. It is so huge that most edge networks cannot be satisfied. Compared with the usual high-speed downlink bandwidth, the uplink bandwidth is often one-tenth of the downlink bandwidth, which makes it impossible to upload a clear enough picture, which greatly affects the user experience. On the other hand, existing research reports show that in China's Wi-Fi network dense areas, there are more than 10 nearby Wi-Fi hotspots available for connection in more than 50% of cases, but about 60% of them are Wi-Fi hotspots....
