Abstract

A fast data synchronization method in optical inter-connected data center is proposed. The origin data are combined to fewer coded data to reduce the synchronization slots. The coded data are broadcast to other nodes. Each node decodes the coded data to recover its missing data. A coding strategy based on coding matrices is proposed for various data distribution. The parity-check matrices in error-control coding theory can be used as coding matrices. The synchronization slots are reduced by the proposed coding method, especially when the missing ratio is low. The slots can be further reduced when the coding field is extended to high-order galois fields.

光互联数据中心的快速数据同步技术

提出了一种光互连数据中心的快速数据同步方法。将原始数据组合成更少的编码数据以减少同步时隙。编码数据被广播到其他节点。每个节点对编码数据进行解码以恢复其丢失的数据。针对各种数据分布，提出了一种基于编码矩阵的编码策略。差错控制编码理论中的奇偶校验矩阵可以用作编码矩阵。所提出的编码方法减少了同步时隙，尤其是在丢失率较低的情况下。当编码字段扩展到高阶伽罗瓦字段时，可以进一步减少时隙。
