基于数据标识的跨域增量数据交换模型

针对传统跨域数据交换模型中存在的待交换数据难以定位以及交换数据量过大等问题，本文提出一套基于动态授权树节点标记名的数据增量交换方式（Increasing Data Exchangingby Distin—guish Name，IDEDN）。IDEDN通过节点在目录上的DN，来控制”自上而下”的同步和”自下而上”的更新。通过对同步点、更新点的记忆，解决增量数据的问题。从而保证数据的单点修改、最少更新、节点同步。在此基础上提出跨域增量数据交换模型，实现高效的跨域数据增量交换。

Cross-domain Increasing Data Exchanging by Distinguished Name

Based on the difficulty to locate the exchanging data and Large amount of data to exchange, this paper innovates increasing data exchanging by distinguished name called IDEDN. IDEDN controls the ＂from top to bottom＂ synchronous mechanism and ＂from bottom to top＂ update mechanisms of data according to node distinguished name on the directory. IDEDN remembers the synchronous points and the update points to solve the problem of increasing data, then guarantees the single point modification, minimum update and node synchronous of the data. The paper innovate the cross-domain in- creasing data exchanging model and achieves the efficient cross-domain increasing data exchange.
