摘　　要：协同网络QoS路由是当前研究的一个热点.针对启发式算法在路由选择过程中,由于算法收敛和资源更新较慢,容易造成单一节点负载不均衡,不能有效提供QoS路由,提出一种适合协同网络QoS路由算法(DBA2COR),该路由算法在应用层和传输层之间设置智能服务路由节点,并在节点上部署启发式算法,自主构建路由选择模型,从负载均衡角度解决启发式算法收敛较慢而导致负载不均衡问题.实验表明,本路由算法自适应性和扩展性较好,在负载均衡方面,DBA2COR使得系统资源分布更加均衡;同时在路由选择方面,DBA2COR相比传统的路由算法,能提供更好QoS路由.Cooperative network QoS routing becomes currently a hot topic. Heuristic algorithm brings about resource imbalance of sin-gle-node due to the algorithm slow refreshing and convergence in the routing process. So, the paper proposes an algorithm suitable for collaborative network QoS routing （DBA2COR）, which by arranging the intelligence service routing node between application layer and transport layer, to construct routing model independently, that mainly solves collaborative network QoS routing from loading bal-ance point. Experiment shows that DBA2COR made collaborative network resources distribution more balanced and more reasonable. DBA2COR which compared traditional routing algorithms shows better performance.
