Communication control apparatus, communication system, information processing apparatus, and communication control method

摘要

In a communication control apparatus, a first receiving unit receives a registration request packet which is generated so as to enable the communication control apparatus to recognize an access requested apparatus, and if determining that the access requested apparatus recognized from the registration request packet exists in a network, registers first identification information identifying an access requesting apparatus which is included in the registration request packet, in a storage unit. A second receiving unit receives an explorer packet, and if determining that first identification information included in the explorer packet has been registered in the storage unit, sends second identification information identifying the own apparatus to the access requesting apparatus.

主权项

1. A communication control apparatus for controlling data communication between a first network and a second network, the communication control apparatus comprising:
a processor; a memory containing program instructions, the processor coupled to the memory executing the program instructions stored on the memory causing the processor to perform a procedure including: receiving a first packet sent from an access requesting apparatus over the first network, and upon determining that an access requested apparatus recognized from the received first packet exists in the second network, registering first identification information included in the received first packet in a storage unit of the communication control apparatus, the first packet being generated so as to include the first identification information identifying the access requesting apparatus and to enable communication control apparatuses which receives the first packet over the first network to recognize the access requested apparatus; receiving a second packet including the first identification information over the first network, the second packet being sent by multicast to search for a communication control apparatus connected to a network which the access requested apparatus is connected to; upon determining that the first identification information included in the received second packet is registered in the storage unit of the communication control apparatus, sending second identification information identifying the communication control apparatus to the access requesting apparatus; and upon determining that the first identification information included in the received second packet is not registered in the storage unit of the communication control apparatus, preventing sending of the second identification information to the access requesting apparatus.
