| Abstract(in English) | In recent years, due to the rapidly grows of the Internet, Network Greening is the important issue. When there are multiple transmission paths between some source and destination nodes and some of links/routers on the minimum hop path is relatively low utilized, it would be effective for energy saving of these links/routers to cut off them and traffic is transmitted on the other path. However, it is difficult to determine these links/routers in advance since the amount of traffic on each link dynamically changes, so that it is desirable that they are fixed based on the topology information. Thus, in this paper, by defining "link betweeness centrality" that is a normalized number of flows if all nodes logically transmits traffic to any other nodes in the network, we propose the determination scheme in accordance with link betweeness centrality. We first show the upper limit of the link reduction rate as energy saving performance in some topologies and investigate the impact of the amount of network traffic on the tradeoff between the link reduction rate and packet loss probability. Moreover, we discuss the control policy of this scheme to autonomously and dynamically cut off/release some links depending on their utilization. |
