Abstract: Dijkstra shortest path algorithm for traditional unicast network transmission is adopted to calculate the shortest path of point-to-point routing. Aiming at this problem, this paper proposes a Quality of Service Routing(QoSR) model to balance network load, resolves the problem of data dynamic and real-time changing route in distributed database system. Experimental results show this model has better stability, it can avoid network congestion.

Key words: Quality of Service Routing(QoSR), data exchange, network load balance

摘要： 传统单播网络传输一般采用Dijkstra最短路径算法建立点到点的最小路径计算。针对此，改进Dijkstra算法，提出一种平衡网络负载的服务质量路由模型，解决分布式数据库系统中数据动态、实时交换路由的问题。实验结果表明，该模型具有较好的稳定性，能避免网络拥塞。
