一种P2P传输方法的优化

Optimization of a Kind of P2P Transmission Method

P2P是目前网络传输中比较重要的技术,从计算机网络本身来讲,可以说是一种计算机网络的自然回归即体现网络创立者的初衷:网络资源的真正共享,我为人人,人人为我。为了更好的解决现有网络负载问题,获得较高的传输性能,尤其是随着高清影片在网络中的传输和在线观看,网络带宽有效的分配,是首要解决的问题之一。在分析现有比较流行的P2P视频点播的系统结构的基础上,提出一种比较优化的传输技术,它有效的将网络中的资源的传输控制在边缘网络中传输,这样可以降低骨干网络流量负载,保证资源在传输或观看中的流畅,防止P2P网络因抢占网络资源造成的网络堵塞,同时也较好的降低了资源定位和查询的时间复杂度。这个优化后的技术有很强扩展性,实用性,鲁棒性,有比较好的实用和推广价值。

P2P is that the network transmission is hit by the comparatively important technology at present.Speaking from the computer network itself,It can be said is a natural return to the computer network that reflect the original intention of the founders of network that anybody shares his resources while making use of network resources.With high definition video in the network transmission and online watching,Efficient allocation of network bandwidth is one of the primary problems in order to better solve the existing network load problem and obtain higher transmission performance..Based on the analysis of existing popular P2P video-on-demand system,The paper proposes a more optimized transmission technology that is an effective method which network transmission is controled in the edge of the network so that it reduces the main network load and ensure the transmission or viewing of the smooth and prevents network jamming.At the same time,it reduces the time complexity of better locating and finding the resource.The optimized technology has strong expansibility,availability,robustness,also has better practical and promotional value.
