Studies on Integrated Network Control Architecture for Green Networking

研究并开发了网络控制体系结构，旨在建立可持续的节能网络系统。我们专注于以下三个子主题：(1)基于峰值流量估计的动态网络重构；(2)无线网络的关联控制节能；(3)有线和无线网络的集成控制节能。特别提出了在全网范围内实现节能和负载均衡的流量聚合/分配方案。此外，为了假设实际网络的运行情况，我们使用流经校园网络的交通信息来评估所提出方案的效率。最后，基于这些子主题的结果，我们评估了有线/无线网络中每个节点自主切换为活动/睡眠模式以节省电力的集成网络控制架构。

We studied and developed network control architecture to aim to establish a sustainable network system for power saving. We focused on following three sub-themes; (1) dynamic network re-configuration based on peak traffic estimation, (2) power saving with association control for wireless networks, (3) integrated control of wired and wireless networks for power saving. Especially, we proposed the traffic aggregation/distribution scheme that achieve a power saving and a load balancing in a whole network. Furthermore, to suppose the operation of actual networks, we evaluate the efficiency of the proposed scheme using traffic information flowing through the network of campus.Finally, based on results of these sub-themes, we evaluated integrated network control architecture that each node in wired/wireless networks changes to active/sleep mode autonomously for power saving.
