Embodiment Construction

[0047] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0048] Through careful study of the existing technology, the main reason for the tailing phenomenon is as follows: when the amount of downloaded data gradually approaches the specified amount of data, eventually, when a thread accumulates the amount of data it has just acquired into the total amount of data T, it will first The discovery task has been completed. But at this time, other threads don't know yet. Maybe it's still sleeping, waiting for packets to arrive, maybe it's still receiving packets. This will cause smearing.

[0049] Such as figure 1 As shown, in order to avoid the occurrence of the above-mentioned problems, the present invention provides a method fo...

Abstract

The invention discloses a method and a system for reducing tailing after the end of downloading. The method comprises the following steps: after a thread completes current transmission, sampling data volumes of all transmissions of the thread to obtain the average data volume of data transmitted by the single thread each time; accumulating data volumes of transmitted data of all the threads to obtain the total data volume of the transmitted data; taking the difference between the total data volume of data to be transmitted and the total data volume of the transmitted data to obtain the data volume of the remaining data to be transmitted; according to the data volume of the remaining data to be transmitted, the average data volume of data transmitted by the single thread each time, and the current number of the threads, determining whether to end the thread. Through the method and the system, the downloading data volume is more accurate, does not surpass an appointed data volume too much, and conforms a user expectation; for the appointed downloading data volume, the downloading time is shortened and the tailing time is reduced.

Description

technical field [0001] The invention relates to a method and system for reducing tailing at the end of downloading, and belongs to the technical field of communication. Background technique [0002] When optimizing a wireless network, it is usually necessary to test the wireless network by downloading files through multi-threaded FTP on a mobile terminal. Measure the peak speed and average speed of downloading. If the average speed is too low, then optimize the network. When some mobile terminals now download by multi-thread FTP, the data volume size (such as 1024K bytes) and the number of threads to be downloaded are generally specified. During the download process, each thread opens an FTP connection to download, and the amount of data downloaded by each thread is accumulated. Once the specified amount (such as 1024K) is reached, each thread closes the connection and then exits. However, when multithreading is used for FTP downloading, the speeds at which each thread clo...
