Problems solved by technology

However, in a general wireless LAN, it is difficult to ensure that multiple terminals have more than one network card. Therefore, the traditional multi-path TCP protocol is not very implementable in deployment.

Abstract

The invention discloses a novel virtual multi-path TCP terminal content scheduling method, which includes: obtaining a file download request from any node in a wireless local area network, the file download request includes a file download request and a download request; The candidate node set of the file, select the optimal download node according to the download situation; if the optimal download node alone downloads the request to download the file and does not meet the download requirements, select the suboptimal download node from the candidate node set until all selected download nodes transmit together Meet the download requirements; start all selected download nodes, and use the virtual multi-path TCP protocol to transfer files to the node that sent the download request; after the file transfer is completed, update the stored file information of all nodes in the wireless LAN. The invention has the following advantages: the file downloading time of the terminal in the local area network is greatly shortened.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a novel virtual multipath TCP terminal content scheduling method. Background technique [0002] With the rapid development of social networks, users in the same WLAN area show a very relevant interest in file downloads. Therefore, the emergence of CDN technology can provide a closer upload node for file downloads of individual end users. However, point-to-point transmission based on traditional TCP can only establish one connection. In the case of insufficient upload bandwidth at the source end, it will cause a waste of bandwidth resources at the download end, resulting in longer download time. [0003] The concept of multipath TCP solves the above problems to a certain extent, but multipath TCP requires at least one of the two parties in the transmission process to have more than one network card, so as to establish multiple TCP transmission paths and jointly transmit a fil...
