Abstract: The paper proposed an encoding scheme of redundancy code, SPM (Shuffled Prime Matrix) code. It was the variation of the popular RS (Reed-Solomon) code. Compared with the latter, SPM was more efficient in time and space and easier to be implemented. Therefore, SPM was more suit for real-time or embedded applications. Based on SPM, an end-to-end QoS controlling scheme was proposed and its benefits were demonstrated.
Key words: Reed-Solomon code, shuffled prime matrix code, IP networks, QoS controlling
摘要: 首先提出一种快速容错编码方法:混洗素矩阵 (ShuffledPrimeMatrix,SPM)码。SPM是对目前广泛应用于非实时环境 (例如RAID磁盘阵列 )中的Reed Solomon冗余容错码的变例。相对于后者,SPM码具有时间效率高、节省内存资源和程序实现简便等优势,因而更适合于实时环境或嵌入式应用的需求。给出了基于SPM码的IP网络端到端的QoS控制方案,并分析了其有益效果。
