| 摘 要： | P2P网络中节点利用阻塞机制作为节点选择算法,以确定节点间相互的服务对象.但是在传统的节点阻塞算法中存在着节点连接时间过高,首块资源获得较慢,系统链路利用率不高等问题.提出一种自适应组播机制,利用动态分组的路由方法,充分考虑各节点间的可用带宽,能够很好的解决在传统阻塞算法中存在的首块资源获取过慢,带宽利用不高等问题.

| Abstract: | Blocking mechanism is used as a node selection algorithm in P2P networks to determine the mutual client nodes.However traditional blocking algorithms may induce several shortcomings such as connection between nodes lasting too long,slow accessing to first block and low link utilization.An self-adaptive multicast mechanism is presented to solve those problems.The use of Considered the available bandwidth,the use of dynamic packets in routing between nodes makes the new algorithm outperform tranditional ones ... |
