Embodiment Construction

[0052] First, a description is given of an outline of the exemplary embodiment. It should be noted that the reference numerals in the drawings attached to this summary are just examples for aiding understanding, and are not intended to limit the present disclosure to the modes shown in the drawings.

[0053] refer to Figure 6 , the control server (100) may include: a node selection unit (51), which selects some nodes included in the first communication network, and generates a second communication network by the selected nodes; a link overhead calculation unit (52), which determines the grouping Forwarding probabilities between nodes in the second communication network and their next-hop nodes, to calculate the forwarding probability between at least a pair of nodes included in the second communication network with respect to a specified service using the determined forwarding probability traffic, and based on the determined forwarding probability and the calculated traffic,...

Abstract

Power consumption of a communication network is reduced, while providing adequate throughput for traffic. A control server selects part of nodes included in a first communication network, generates a second communication network from the selected nodes, determines a forwarding probability of a packet between a node and its next hop node in the second communication network to calculate a communication volume between at least one pair of nodes included in the second communication network with respect to a prescribed traffic using the determined forwarding probability, and calculates a link cost for at least one pair of nodes included in the second communication network based on the determined forwarding probability and the calculated communication volume, adds at least one node included in the first communication network to the second communication network so that the calculated link cost satisfies a prescribed condition, and puts nodes not included in the second communication network in a low power consumption mode.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims priority from Japanese Patent Application No. 2011-082887 filed on April 4, 2011, the entire disclosure of which is incorporated herein by reference. technical field [0003] The present invention relates to a control server, a network control method and a program, and more particularly to a control server, a network control method and a program for controlling power supply to nodes deployed in the network while maintaining communication capabilities in the network. Background technique [0004] There is known a communication system in which a communication network including a plurality of nodes is centrally managed by a management server. When receiving a request to set a path related to a service, the management server determines a communication path of the service of interest in the communication network. Hereinafter, the management server that determines the communication pa...
