An information processor includes a receiver configured to receive, from a first device, a response information request including content identification information for identifying a content in a network; an extraction portion configured to extract a plurality of element information pieces included in the content identification information; a storage to store therein each of conditions for a first element information piece among the plurality of element information pieces, and a response information piece in association with each other; and a generator configured to generate a response message including the response information piece stored in association with a condition that the first element information piece extracted by the extraction portion satisfies among the conditions for the first element information piece stored in the storage portion.
摘要:
According to an embodiment, a communication apparatus controls controllable nodes. The apparatus includes an acquisition unit and a generation unit. The acquisition unit acquires at least one of a first evaluation value indicating an occurrence frequency of a control request to a target controllable node and a second evaluation value indicating an occurrence frequency of communication error at the target controllable node. The generation unit generates identification information to be assigned to control the target controllable node in a manner such that a bit length of the identification information becomes shorter as at least one of the first evaluation value and the second evaluation value increases.
