BitTorrent下基于活跃度的传输节点选择算法
Node Selection Algorithm of BitTorrent Based on Node Activity Level
摘要
Abstract
In recent years, the peer to peer (P2P) has become the key support technology of the efficient distribution of big data. As the node selection algorithm in the BitTorrent Tracker server of the P2P file distribution system does not consider the problem of node liveness, this paper introduces a liveness-based Tracker server node selection algo-rithm. This algorithm can search for the high liveness nodes to build a more efficient distribution network that fits the demand of requesting nodes and boosts their download procedure. The experimental result verifies that the improved node selection algorithm can reduce file download time and improve the efficiency of the distribution network.关键词
