Communication apparatus provided with network interfaces, control method therefor, and storage medium storing control program therefor

摘要

A communication apparatus is provided with network interfaces. A control unit provides an application programming interface for an application that runs on the communication apparatus. A transmission unit transmits a search packet via the respective network interfaces in response to a request from the application. A reception unit receives a response packet in response to the search packet that the transmission unit transmits. A first determination unit determines whether the information showing a transmitting source of the response packet that the reception unit received is stored in a storage unit. The control unit stores the information showing the transmitting source of the response packet received into the storage unit and transfers the response packet received to the application, when the first determination unit determines that the information showing the transmitting source of the response packet received is not stored in the storage unit.

1. A communication apparatus provided with a first network interface and a second network interface, comprising:
a memory; a processor connected to said memory, the processor configured to: transmit a search packet; receive a packet; determine, in a case where a packet is received, whether or not the received packet is a response packet responding to the transmitted search packet; and transfer, in a case where a first packet is received via the first network interface, and a second packet is received via the second network interface, and it is determined that the received first packet is a first response packet responding to the transmitted search packet and the received second received packet is a second response packet responding to the transmitted search packet, and the source address of the first response packet and the source address of the second response packet are identical, one of the first response packet and the second response packet to an application running on the communication apparatus without transferring the other of the received first response packet and the second response packet, wherein, in a case where it is determined that a received packet is not a response packet responding to the search packet, the received packet is transferred to the application.
