Embodiment

[0042] Such as Figure 1 ~ Figure 3 Shown is a multi-stream concurrency control method for multi-file transmission in a multi-homed network environment. First, the host network server needs to obtain the status information (such as SNR and network bandwidth W) of each host network in the multi-homed network environment where the client is located. The server performs reasonable scheduling based on this information and the file size information requested by the client to download. Distribute multiple files to multiple links for concurrent transmission. Make the time consuming for multiple file transfers the shortest. Its special feature lies in the use of heterogeneous network information for file scheduling in a multi-homed network environment to achieve concurrent transmission of multiple files and multiple streams, which improves the utilization of network resources.

[0043] The specific implementation steps are as follows:

[0044] 1. The server is connected to the IP core n...

Abstract

The invention discloses a control and dispatching method of multi-file simultaneous-transmission in a multi-host network environment. In the multi-host network environment, a client and a server are both in various heterogeneous network environments, a plurality of files are dispatched by acquiring ubiquitous network information (such as signal-to-noise ratio (SNR)), and the files are transmitted simultaneously by fully utilizing multiple links. Therefore, multithread and simultaneous transmission of the multiple files in the multi-host network environment is achieved, and the network transmission efficiency is improved.

Description

Technical field [0001] The invention belongs to the field of multi-host network concurrency control, and specifically relates to a scheduling and control method for multi-file multi-stream concurrent transmission in a multi-host network environment. Background technique [0002] Ubiquitous Network (Ubiquitous Network) refers to the ubiquitous network, that is, a communication network that can realize any time (Anytime), any place (Anywhere), anyone (Anyone), and anything (Anything). Since any digital terminal in the ubiquitous network can use the broadband network anytime and anywhere, the concept of the traditional network is extended to a wider area and penetrates into all aspects of people's lives, which has amazing application prospects. Ubiquitous networks are increasingly being valued by many countries and related international organizations. Japan proposed the "U-Japan" strategy in 2004, and South Korea followed Japan and established the U-Korea plan. The ubiquitous netwo...
