基于改进蚁群算法的数据邮递QoS模型

Model of Data Mail QoS Based on Improved Ant Colony Algorithms

分布式数据交换网络系统中,海量数据传输一直是数据交换的难题。在进行路由选择时通常考虑跳数和时延,不提供QoS保证,致使数据在传输过程中因阻塞或中断长时间延时、严重的长时间延迟而丢弃。提出了改进的蚁群算法构造数据邮递过程的QoS模型,以实现满足QoS约束、均衡链路负载、快捷高效的海量数据传递。

In the network system of distributed data exchange,the exchange of massive data is a key problem.The employed hop and time delay are consided during a routing selection,and there is not QoS guarantee.The data packages in the transmission process are delayed a long time for obstruction or interrupt,and some of them are discarded for seriously delay.In this paper,the model of data mail QoS based on improved ant colony algorithms realizes the data mailing with satisfaction of QoS routing,load balance and efficiency.
