摘要
P2P是当前互联网上的热点技术之一。P2P技术的本质是化集中处理和存储为分布处理和存储,将闲散的资源集中起来使用,因此它是一种很有创意的技术,一种很好的技术,有着十分广阔的使用前景。文章首先将P2P网络结构与传统的C/S网络结构进行了对比,总结了P2P技术在利用网络中的大量闲置资源,避免服务器带来的瓶颈问题,降低网络成本等方面的优势。然后,对P2P技术的特点以及P2P技术的发展过程作了简要分析。最后,讨论了P2P技术在文件交换、对等计算、协同工作、即时通信和搜索引擎等方面的应用以及面临的挑战。
P2P is one of the hot technologies on the Intemet. The essence of P2P technology is to change the way of Processing and storage from centralization to distribution. This architecture can centralize the idle resources for using. Therefore, it is a very innovative and good technology. It has very broad prospects for application. First, this paper have made a comparison between P2P and the traditional C/S network structure and summed up the advantage of P2P technology in the use of a large number of idle resources, to avoid bottlenecks caused by the server and reduce cost of network. Then, this paper has made a brief analysis about the characteristics and the development of P2P technology. Finally, this paper discusses the use of P2P technology, such as resource sharing, distributed computing, collaborative work, instant messaging and search engines etc., and the challenge in the future.
