Abstract: A first calculation unit calculates the heart rate of a subject from a plurality of instantaneous heart rates by averaging processing with an IIR filter using a first coefficient. Note that the first coefficient is a numerical value less than 1, and is a fixed value. A second calculation unit calculates the heart rate of the subject from the plurality of instantaneous heart rates by averaging processing with an IIR filter using a second coefficient. The second coefficient is a numerical value less than 1, and is a variable value. A switching unit switches between the first calculation unit and the second calculation unit based on a difference between the precedingly calculated heart rate and a latest instantaneous heart rate.

Abstract: A network device (PE), a network control method and program which can reduce a BUM traffic packet loss even when a time is taken for route recalculation according to a routing protocol due to a malfunction in a network infrastructure are provided. A network device according to the present invention requests each PE connected to the same ES as that of the network device to perform DF reelection on the basis of a redundant PE list from which the network device has been deleted when cease of a BGP session is detected.
