Generalized Piggybacking Codes for Distributed Storage Systems
题目：Generalized Piggybacking Codes for Distributed Storage Systems
报告人：黄勤 副教授 （北京航天航空大学）
摘要: This talk generalizes the piggybacking constructions for distributed storage systems by considering various protected instances and piggybacked instances. Analysis demonstrates that the proportion of protected instances determines the average repair bandwidth for a systematic node. The generalized codes cost much less repair bandwidth than the previous piggybacking codes by optimizing the proportion of protected instances. Asymptotically, the average repair bandwidth as a fraction of the original messages approaches zero instead of 50% as the number of parity check nodes tends to infinity.
