Multicast traffic is transferred, via routers, from a sender to receivers through a delivery tree that is determined based on a multicast routing protocol and includes delivery paths each communicably coupling the sender and one receiver. A router includes a multicast routing table used for transferring the multicast traffic through the delivery tree. The router generates delivery path information on first and second delivery paths each communicably coupling the sender and the router. Upon detecting a link failure on the first delivery path, the router performs delivery-path change processing that switches a first pair of interfaces along the first delivery path to a second pair of interfaces along the second delivery path without waiting for the multicast routing table being updated using the multicast protocol, and transmits a delivery-path change message to routers along the second delivery path so that the routers perform the delivery-path change processing.

An information input device includes a touch panel configured to be provided with a touch sensor that detects a position at which a sensing object is brought close to a sensing surface. In this information input device, the touch sensor has a scanning electrode and a detecting electrode that is opposed to the scanning electrode with the intermediary of a dielectric substance, and is a capacitive sensor whose electrostatic capacitance changes if the sensing object is brought close to the detecting electrode. Furthermore, a slit is formed in a surface of the detecting electrode opposed to the scanning electrode.
