    • In a routing apparatus, a state data reception unit identifies target paths involving a specified link and finds candidate paths which share their beginning and ending routing apparatuses with any one of the target paths and do not involve the specified link. The state data reception unit obtains state data of each candidate path from a management apparatus managing state data indicating states of routing apparatuses that forward traffic on the candidate paths. Based on the state data of each candidate path, a distribution path selection unit selects a distribution path that minimizes the increase in power consumption due to an expected change in the states of routing apparatuses. A distribution requesting unit transmits a distribution request to the beginning routing apparatus of a target path so as to distribute at least a part of the traffic on the target path to the selected distribution path.
    • 在路由设备中,状态数据接收单元识别涉及指定链路的目标路径,并且找到与目标路径中的任何一个共享其起始和结束路由设备的候选路径,并且不涉及指定的链路。 状态数据接收部从管理表示候选路径的转发路由装置的状态的状态数据的管理装置获取各候补路径的状态数据。 基于每个候选路径的状态数据,分配路径选择单元选择由于路由设备的状态的预期变化而最小化功耗增加的分配路径。 分发请求单元向目标路径的起始路由设备发送分发请求,以将目标路径上的业务的至少一部分分发到所选择的分配路径。

    • A video quality monitoring method includes a distribution server measuring first video quality index values according to a full-reference method by comparing a video, distributed from the distribution server to a client through a network, with a degraded video, generated by causing multiple scenarios of quality degradation due to the network in the video in a pseudo manner, creating characteristic data of first quality degradation values, obtained by causing the quality degradation to vary with the scenarios at regular intervals, and the first video quality index values corresponding to the respective scenarios, and transmitting the characteristic data to the client; and the client measuring a second quality degradation value in the video distributed through the network, and calculating a second video quality index value, equivalent to a value according to the full-reference method, of the distributed video from the measured second quality degradation value and the characteristic data.
