　各个线程任务分配是这样实现的。在开始下载时，文件平均分成若干块进行下载。如第一个线程一开始的任务是从文件的0位置开始下载一直到72908位置处。线程1每次下载一块数据后就要调整任务，如第一次下载了20800字节的数据，那么线程1的任务将改为：20800-72908。如此下去，直到任务为72908-72908时表示线程1完成了当前的下载任务。此时，线程1就分析各个线程的任务，找出任务最为繁忙的一个线程：如线程3：14816-218724。那么线程1就自动去调整任务，拿50%的任务来再次下载。周而复始直到各个线程都完成任务。不过这里有一点需要注意：为了避免重复下载部分数据，在调整任务的时候，起始的文件便移量必须加上接受缓冲器的字节数，因为如前面所举的列子来看。线程1和线程3在平衡负载的时候，线程正在下载数据，如果所剩的数据比接受缓冲器的大小还小，线程1和线程3的部分下载数据将会重复。 　　在调整任务和分析任务的时候，会发现一个问题。就是读取文件数据太过频繁。于是我用了一个数据结构。在下载文件的过程中始终打开配置文件，这样速度提高了很多。在文件下载完毕后关闭文件。-various threads assignment is achieved. At the beginning of the download, the paper divided into a number of pieces of the download. As a thread of a task is to start from the position paper of 0 to start the download has 72,908 locations Department. Thread a download each one will have to adjust the data tasks, such as the first downloaded 20,800 gigabytes of data, then threaded a task will be re :20800- 72908. This situation continues until the mandate of 72908-72908 said threaded a completion of the cu

直接用socket实现HTTP协议(下载专用) 作者:北方工业大学2000级计算机4班 querw 从HTTP服务器上下载一个文件有很多方法,"热心"的微软提供了WinInet类,用起来也很方便.当然,我们也可以自己实现这些功能,通过格式化请求头很容易就能实现断点续传和检查更新等等功能.- Straight takes over the use of socket to realize the HTTP agreement (special-purpose downloading) the author: North industrial university 2,000 levels of computers 4 class of querw downloaded a document from the HTTP server to have very many methods, the "warm-hearted" Microsoft has provided the WinInet kind, used very to be also convenient Certainly, we also may own realize these functions, is very easy through formatted request to be able to realize the break point to continue passes on and inspects renewal and so on function
