容错分布式热数据存储中Mojette纠删码的性能评估
Performance evaluation of the Mojette erasure code for fault-tolerant distributed hot data storage
摘要：
数据包擦除码是当今容错分布式存储系统中复制的真正替代方案。在本文中，我们提出了基于Mojette变换（以前的层析工具）的Mojette擦除码。编码和解码的性能进行了比较，里德-所罗门代码实现的两个开源的参考库，即ISA-L和Jerasure 2.0。结果清楚地表明，我们的离散几何代码相比，经典的代数方法有更好的性能。与ISA-L Intel相比，测量的增益系数高达$2$。这些非常好的性能允许部署Mojette擦除码用于热数据分布式存储和I/O密集型应用。
英文摘要：
Packet erasure codes are today a real alternative to replication in fault tolerant distributed storage systems. In this paper, we propose the Mojette erasure code based on the Mojette transform, a formerly tomographic tool. The performance of coding and decoding are compared to the Reed-Solomon code implementations of the two open-source reference libraries namely ISA-L and Jerasure 2.0. Results clearly show better performances for our discrete geometric code compared to the classical algebraic approaches. A gain factor up to $2$ is measured in comparison with the ISA-L Intel . Those very good performances allow to deploy Mojette erasure code for hot data distributed storage and I/O intensive applications.
