Sina technology news, Beijing time on April 11 News, according to foreign media reports, a research team composed of Carnegie Mellon University, Pudu University and Intel developers recently announced that, A new technology they developed can accelerate P2P download by 30% to 70%.
P2P file sharing can greatly increase the download speed, because it can effectively avoid the problem of excessive load on a single server. However, if the file seed has just appeared, or there are too few active users, the advantages of P2P download will be hard to reflect. A research team consisting of Carnegie Mellon University, Pudu University, and Intel developers recently announced that a new technology they developed, "similarity-enhanced transfer" (SET), can break this bottleneck, this increases the P2P download speed by 30% to 70%.
Many shared files contain the same data, which is the basis of the set technology. For example, some shared music files may only have different tags, some movie files may only have different languages, some software may only have different versions, but they all contain a large amount of the same data. Similar to other P2P systems, set also splits large files into multiple small files. After this process is completed, set will use a method named "handprinting" to search for similar files. After a similar file is found, set scans it to determine which parts are the same as the files you want to download.
In this mode, set greatly extends the available sources of files. The Set Technology performs well in lab tests. It can download 30 mb of movie files within 1/3 of the time, and the time for downloading MP3 files can even be shortened by more than 70%. However, this technology cannot be added to the existing P2P network in the short term, because everything is still in the experimental stage. (Otto)
