Abstract

一种存储系统及数据交叉方法，涉及光传输网络技术领域，用于解决现有技术的数据交叉过程中存在物理线路拥塞的问题。该存储系统包括控制逻辑(101)，以及与存储器(102)耦合的写入控制接口(103)和读出控制接口(104)，该存储器(102)的存储区域包括第一页面和第二页面，该控制逻辑(101)用于：基于对第一页面和第二页面的乒乓使用，以通过写入控制接口(103)将以时分形式输入的数据写入该存储区域中、以及通过读出控制接口(104)将该存储区域中包括的数据以时分形式输出，从而完成预设时隙数内的数据的交叉。其中第一页面和第二页面的深度均与预设时隙数相等，从而能够以最小的存储区域实现数据的交叉，从而具有物理实现性好和资源最省的优势。
