网络编码系统中基于访问频度的数据重建方法
A frequency-based data rebuilding method in network coding file system
摘要
Abstract
In order to keep data avialablity , it is necessary to introdue new disk and rebuild data after disk failure . Network coding have been playing a more and more important role in the data rebuild process for it′s advanced feature that it can achieve optimal download bandwidth during rebuild process by making linear combinations inside the surviving disk node . In the meantime , the combination operations also bring a mount of time comsumption , which greatly lower rebuild efficiency and increase data request time . We promote a new rebuild method based on 80/20 rule in Network Coding File System ( NCFS ) . Implementation and simula-tion are given . Experiment result shows that new system makes great performance improvement in rebuild time , response time and throughput .关键词
