Path selection apparatus, path selection method and program

A path selection apparatus in a sensor tree includes a node moving unit that selects a first node in the sensor tree, and moves a second node to under a third node in the sensor tree if the total number of packets transmitted and received in the sensor tree is reduced as a result of the second node being moved to under the third node, the first node having a child node under the first node, the second node being located under a subtree of which a vertex is the first node, the third node not belonging to the subtree. If nodes under the subtree of which the vertex is the first node do not include anode that reduces the total number of packets as a result of being moved, the node moving unit moves a node that is included in the nodes under the subtree and does not change the total number of packets, to under the third node.

An optical fiber component comprises an optical fiber that transmits light; and a coreless fiber that is connected to the end surface of the optical fiber and prevents foreign matter from adhering to the end surface of the optical fiber. The optical fiber and the coreless fiber are connected by fusing one end surface of the coreless fiber to the end surface of the optical fiber. The core section on the end surface of the optical fiber is no longer exposed to the air. Moreover, the power density of light that is input at the core of the optical fiber is greatly reduced more than when there is no coreless fiber, so it is possible to prevent compounds of C, H and O from adhering to the core of the optical fiber.
