Analysis for RS-coding and fountain-code for erasure coding

Abstract

This research provides an in-depth analysis of RS-coding and fountain-coding for erasure cod-ing, focusing on the different circumstances that data storage may face during daily usage. The essay outlines the fundamental information of RS-code and fountain-code, and com-pares their effectiveness in addressing varying degrees of erasure in the data disk. The research includes case studies and content analysis to identify appropriate circumstances for using dif-ferent coding methods. Based on these findings, the research concludes that RS-coding is more effective when fixing erasures up to a certain limit, beyond which fountain-coding is a better option. Finally, the research presents a research example to demonstrate the practical usage of different coding methods in specific circumstances, highlighting the advantages and disad-vantages between the two coding systems. Overall, this research provides valuable insights into erasure coding and can aid in optimizing data storage systems for efficient and reliable per-formance.
