由于许多节目和内容，如电影文件，都是通过互联网传送的，并且副本通常存储在分布式服务器中，以减轻原始服务器的负载，缓解网络拥塞，并缩短响应时间。要检索对象文件，现有方法只需选择一个或多个服务器。这种方法将文件分成大小由先验确定的等分块。此方法不适用于提供可变带宽的网络。为了更好地利用可变带宽，我们提出了一种自适应下载方法，并通过在Internet上进行的实验对其进行了评估。结果表明，该方法是有效的，将成为一种重要的网络控制技术保证。
As a lot of programs and contents such as movie files are being delivered via the Internet, and copies are often stored in distributed servers in order to reduce the load on the original servers, to ease network congestion, and to decrease response time. To retrieve an object file, existing methods simply select one or more servers. Such methods divide a file into equal pieces whose size is determined a priori. This approach is not practical for networks that offer variable bandwidth. In order to more utilize variable bandwidth, we propose an adaptive downloading method We evaluate it by experiments conducted on the Internet. The results show that the new method is effective and that it will become an important network control technology for assurance.
