Communication station, communication control program, and communication network system

摘要

There is provided with a communication station including: a receiving unit, a determining unit, a transmitting unit and a reachability testing unit wherein the receiving unit receives a packet from a network in which a plurality of communication stations are interconnected, the determining unit determines whether the receiving unit receives a first packet in which a transmission source address is an address of a first communication station, the transmitting unit transmits a reply request packet to request a reply to the first communication station, and the reachability testing unit omits for the transmitting unit to transmit the reply request packet when the first packet is received before the transmitting unit transmits the reply request packet.

1. A communication station comprising:
a receiving unit, implemented by a processor, configured to receive a packet from a network in which a plurality of communication stations are wirelessly interconnected; a determining unit, implemented by the processor, configured to determine whether the receiving unit receives a first packet in which a transmission source is an address of a first communication station and a transmission destination address is an address of another communication station different from the first communication station among the plurality of communication stations; a transmitting unit, implemented by the processor, configured to transmit a reply request packet to request a reply to the first communication station; and a reachability testing unit, implemented by the processor, configured to control so that the transmitting unit does not transmit the reply request packet when it is determined that the first packet has been received before a predetermined timing and transmits the reply request packet when it is determined that the first packet has not been received before the predetermined timing.
