BT authors refer to Microsoft's technology as avalanche's inherent deficiency

Sina technology news Beijing Time on June 23 news, BitTorrent founder blam-Cohen (Bram Cohen) recently said, the P2P file sharing technology "Avalanche", which is being developed by Microsoft's Cambridge lab in the UK, is completely a type of FOG (Vaporware, usually a product that has announced a development plan but has been jumping for a long time) and is of no use. Cohen said that Microsoft claims avalanche has solved the BitTorrent transmission rate and disconnection problem, which is completely nonsense. He said in his network logs that most of Microsoft's experiments were completed in a simulated environment, without considering different transmission rates and user computer restrictions, therefore, there are congenital defects in the test results. "The biggest problem with avalanche is disk access. If the size of the file to be transferred exceeds the memory size, continuous hard disk addressing and reading will lead to a dramatic reduction in computer system performance," he said. Although avalanche is different from BitTorrent, the two work in roughly the same principle. They all split a large file into multiple parts, end users can download various file fragments from other users' hard disks and restore them to the original file after the download is complete. Currently, BitTorrent and other systems have a disturbing problem, that is, sometimes users need to wait a long time to download the last few file fragments, if the client is disconnected or the client is in short supply, the user will wait longer. Microsoft said avalanche had solved the above problem. Before a file is published, you can use specialAlgorithmEncoding. Each encoded file segment contains information about other parts of the original file. Therefore, you do not need to wait until the last file segment is downloaded. Microsoft researchers said avalanche could increase the download speed by 20% to 30%. Of course, Cohen does not agree with this statement. David Card, analyst at Jupiter Research, said it is hard to tell why Microsoft launched its own P2P service, in particular, the company is developing digital rights management technology to win the trust of entertainment companies. Joe laslow, another analyst at Jupiter, said that from another perspective, Microsoft developed avalanche to show that it is not against P2P sharing, it only opposes illegal P2P sharing. Microsoft has previously announced that the avalanche system can prevent users from distributing copyrighted patent protection content, because avalanche only forwards files with the publisher's digital signature. A Microsoft spokesman said: "avalanche has added a powerful protection mechanism to effectively protect content providers from piracy and prevent unauthorized third-party content downloads ." Raso said that the reason why Microsoft did not buy BitTorrent or other similar software is simple, but it is to ensure the legitimacy of the software. Ashin Navin, chief operating officer of BitTorrent, said Microsoft's development of P2P technology would not concern the company because BitTorrent is backed by the support of developers and users. He said: "In the network market, the premise for a new product to win is that it has obvious advantages. Apart from strong financial support, we cannot see this in Microsoft products ." (Moore)
