Abstract

This invention discloses a method incorporating both multiple-point transmission mechanism and break-point retransmission mechanism to download data from network terminals. This method includes the following steps: first establishing a communication protocol and connecting the same to a server with a data file to be downloaded; then, acquiring the updated time of the data file to be downloaded from the server; next, determining whether the data file was downloaded before, and if not, conducting the procedure to download the data from the very beginning, otherwise, comparing the updated time of the data file in the server with that in the management datasheet to see if they are the same; finally, conducting the break-point retransmission procedure. If the updated time of the data file in the server is the same as that in the management datasheet, this data file and the related information in the management datasheet are eliminated and the aforementioned procedure is conducted to download the data from the very beginning.

Method for downloading data from a network terminal with a transmission mechanism [2] BACKGROUND OF THE INVENTION: In today's era of the development of Beixun's network, the use of computers and communications does not swell, which increases the frequency of contact between people through the network. It is an undeniable fact that the Internet is in power. With the rapid development of society, it has become a trend whether individuals, groups, or businesses operate through the Internet. Various applications relying on computers and communications have emerged endlessly, and information network processing equipment ’has sprung up in every corner of life. In just a few years, the Internet has swept the world. In addition to being cheap, the most important thing is that "Internet has no borders." The Internet is a global wide-area network. This network connects schools, government organizations, and various research units around the world using electric or private lines. Users can communicate with others on any connected network. Messaging, sending emails or files, there are currently more than 20 million computers connected to this system worldwide. The most commonly used services on the Internet are email (E-mail) and file transfer (FTP). The other Internet is called Cyberspace. This is because the Internet formed

At present, many Internet terminal products have appeared on the market, with functions such as sending and receiving emails and downloading data from the Internet. The download uses the traditional method 'that is, a simple transmission control / Internet protocol (generation? / 1?) Data transmission process: first the client ((: 11 € 111;) and the server (Server) A TCP handshake connection is established between them; then the client sends a download command to the server, and the server sends data to the client until completion: Finally, the TCP security disconnection between the client and the server is completed. This traditional practice is in the Internet It is feasible when the network transmission is normal. However, when the transmission is not normal to the Internet congestion, or when downloading large data, it will cause many problems. First, the download speed is very slow, and second, it will greatly increase the TCP disconnection. Possibility 'thus prevents the download from being completed. If Tcp is disconnected, the previously downloaded data will be lost. This will not only waste time, but also waste resources. In addition, the existing application software that improves download speed is used more on personal computers, Like a network ant, it can greatly improve the speed and efficiency of downloading large-capacity data. However, it also has certain disadvantages: if the downloaded content is more New, the content after the resumption cannot be matched with the previously downloaded content, the effect is equivalent to a failed download, and the reliability is not enough. In short, there is no high-efficiency, high-reliability on the current Internet terminal. The method of loading data. Therefore, in order to solve the shortcomings and disadvantages of the method described above, a new implementation method is urgently needed, that is, a method that can provide

Application for Patent Scope 10. For the method of application for Scope 7 of the Patent Application, the above management form is stored in a readable / writable recording medium known by the user, which at least records : ° An identification code 'It is used to mark the data file; It is used to record the new time of the data file in the server; 忒 Data length, which records the total length of the data file Degrees; the starting position of each segment; and the download length of each segment. U. A method for downloading a data file on a network terminal with a point transmission mechanism and a breakpoint continuous transmission mechanism, the method includes at least the following steps: ^ π f 5fl protocol is connected to a server storing the data file Get the update time of the data file in the server; determine whether the update time of the data building in the server is the same as the update time of the data file in the management form; π of the master download data For example, if the data in mm 5 is cut, the update time of the data broadcast in the management table ^ read the segment length of the data file and the start position of each segment in the management table;畀 The split knife activates N-1 communication protocols to connect to the server; instead, the protocol connection downloads the data of the data file to the server and modifies the management form according to the download status; 4 53 0 8 3 VI. Scope of patent application — delete the relevant information of the data file in the management form, such as note that all N communication protocol connections have been downloaded, otherwise continue downloading; ^ close the N communication protocol connections. 1 2 _If the method of claim 11 of the scope of patent application, wherein the above-mentioned data program from the beginning includes at least the following steps: divide the data length of the data file into N segments; find the beginning of each segment according to the length of each segment Position; write the update time, data length, segment length, and segment start position of the data file in the server into the management table; start N-1 communication protocols to connect to the server; via the N communication protocols are connected to download the data of the data coffin to the server and modify the management form according to the download status; Just remove the relevant information of the data file in the management form, such as the N communication links All downloads are complete, otherwise continue downloading; and close the N protocol connections. 13. | The method according to item 12 of the patent application, wherein the above-mentioned communication protocol includes at least the Transmission Control / Internet Protocol (TCP / IP). 14.
