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.
Coordinated network QoS routing is a hot topic in the current research.For the heuristic algorithm in the routing process, due to convergence of algorithms and slow resource updates, it is easy to cause a single node load imbalance, can not effectively provide QoS routing, a suitable collaborative network QoS routing algorithm (DBA2COR). The routing algorithm sets up intelligent service routing nodes between the application layer and the transport layer and deploys heuristic algorithms on the nodes to build a routing model. From the view point of load balancing, the heuristic algorithm converges slowly Which leads to the problem of unbalanced load.Experiments show that the proposed routing algorithm has better adaptability and scalability, and DBA2COR makes the system resource distribution more balanced in terms of load balancing. Meanwhile, compared with traditional routing algorithms, DBA2COR Provide better QoS routing.
