一种基于位向量的位置索引压缩方法
Novel location-index compression mechanism based on bit vector
摘要
Abstract
To reduce the stress brought by shared resource in large-scale distributed system, tlis paper put forward a kind of novel location-index compression mechanism based on bit vector. It established on hybrid overlay network that was composed with three levels of district/site/node and peer-to-peer district level. After mapping sub nodes of district and site level agent nodes to corresponding bit vector, the location-index of many same replicas could be compressed to one record by bottom-up location-index publish and aggregating. Meanwhile, replicas in system could be located by query on corresponding bit vector.Application and experimental results indicate that this method can achieve high record compression ratio and improve the replica location efficiency.关键词
