Abstract
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.
Claims11
A reception apparatus constituting a communication apparatus that performs one-to-many communication with a plurality of counterpart communication apparatuses, which are respective sources of packets, the reception apparatus comprising:
- a packet processor that processes packets;
- a buffer that (i) includes a timer to count an interval between sequential output of packets received from the plurality of counterpart communication apparatuses to the packet processor each time the buffer outputs one of the received packets to the packet processor, (ii) adjusts the interval between packets to control when the received packets are sequentially output to the packet processor to a specified value or more, (iii) and sequentially outputs the received packets to the packet processor according to the adjusted interval;
- and
- a filter that extracts packets of a specific kind from the packets received from the plurality of counterpart communication apparatuses, outputs the extracted packets to the buffer, and discards packets other than the specific kind, wherein the filter is configured to extract packets for a specified time period during which a greater number of packets are received from the plurality of counterpart communication apparatuses.
A reception apparatus constituting a communication apparatus that performs one-to-many communication with a plurality of counterpart communication apparatuses, which are respective sources of packets, the reception apparatus comprising:
- a packet processor that processes packets of a specific kind;
- a filter that extracts packets of the specific kind from packets received from the counterpart communication apparatuses, outputs the extracted packets, and discards packets other than the specific kind, wherein the filter is configured to extract packets for a specified time period during which a greater number of packets are received from the plurality of counterpart communication apparatuses;
- and
- a buffer that receives the extracted packets from the filter and sequentially outputs the extracted packets to the packet processor in accordance with a timer interval each time the buffer outputs one of the extracted packets to the packet processor, wherein the timer interval specifies a time between the sequential output of the extracted packets to the packet processor and the buffer adjusts the timer interval to a specified value.
A reception apparatus constituting a communication apparatus that performs one-to-many communication with a plurality of counterpart communication apparatuses, which are respective sources of packets, the reception apparatus comprising:
- a filter that extracts packets of a specific kind from packets received from the counterpart communication apparatuses outputs the extracted packets, and discards packets other than the specific kind, wherein the filter is configured to extract packets for a specified time period during which a greater number of packets are received from the plurality of counterpart communication apparatuses;
- a buffer that has a plurality of packet storing regions that are respectively associated with each of the plurality of counterpart communication apparatuses on a one-to-one basis, wherein the buffer stores the extracted packets output by the filter in the packet storing regions respectively associated with the plurality of counterpart communication apparatuses;
- and
- a packet processor that processes one or more of the packets stored in the buffer in a state in which a processing load of the packet processor is lower than a specified value,
- wherein the packet processor receives one or more of packets from the buffer in accordance with a timer interval, wherein the timer interval is adjustable and specifies a time between the sequential output of the one or more packets from the buffer to the packet processor.
