The present invention provides a reception apparatus constituting an information-control central apparatus that is a communication apparatus that performs one-to-many communication with devices as a plurality of counterpart communication apparatuses. The reception apparatus includes a packet processor that processes a received packet and a buffer that, in response to input of a packet received from a counterpart communication apparatus, adjusts an interval between packets to be sequentially inputted to the packet processor to a specified value or more and outputs the input packet to the packet processor, thereby to avoid occurrence of packet loss.
