摘要:

针对命名数据网络流量全局性优化调度问题,分析已有工作,提出一种基于集中控制的方法。所提方法兼顾网络性能与通信开销,先选择合适节点作为E-NDN节点,再利用控制器根据网内缓存、Interest包聚合情况和热门内容的流量需求计算相应的多路径转发策略并下发至 E-NDN 节点,以达到全局性优化的目的。实验结果表明,所提方法可显著降低最大链路利用率,提高网络性能,同时优化代价较小,控制器与节点间的通信开销仅略有增加。

Abstract:

In order to address the global optimization problem for traffic scheduling in named data networking,related works were analyzed,a method based on centralized control was proposed.The proposed method took network performance and communication overhead into account.In the proposed scheme,appropriate nodes would be selected as E-NDN nodes,then the controller calculated the corresponding multi-path forwarding policies and sent them to E-NDN nodes according to the in-network cache,the aggregation of Interest packets,and the traffic demands of popular contents to achieve global optimization.The evaluation results indicate that the proposed method can significantly reduce the maximum link utilization and improve network performance.Simultaneously,the proposed method will not cause a large optimization cost,and communication overhead between the controller and nodes will increase slightly.

Key words: named data networking, centralized control, traffic scheduling, hybrid network, linear programming
