分布式数据库系统动态数据邮递的QoS模型

摘要

在信息通讯中传统的单播网络传输，一般采用Dijkstra最短路径算法来建立点到点的最小路径计算。文章针对广域网分布式数据库系统动态、实时数据交换路由问题，对传统的单播网络传输的Dijkstra算法进行改进，提出了一种平衡网络负载的QoS的路由算法。%Information and communication in traditional unicast network transmission of general use Dijkstra shortest path algorithm to establish point-to-point shortest path calculation. In this paper, based on the dynamic and real-time data exchange routing problem of the distributed database system, the traditional unicast network transmission Dijkstra is improved, and a routing algorithm of QoS is proposed to balance the network load.
