Abstract

A communication device includes a recognition unit configured to recognize a service provided by a network, a generation unit configured to generate a packet to be transmitted to an external device that provides the service recognized by the recognition unit based on a priority set to the packet according to the recognized service when the service is recognized by the recognition unit, and a connection unit configured to establish a connection with the external device using the packet generated by the generation unit.

Claims

1. A communication device comprising:

a recognition unit configured to recognize a service provided by a network;

a generation unit configured to generate a packet to be transmitted to an external device that provides the service recognized by the recognition unit based on a priority set to the packet according to the recognized service, when the service is recognized by the recognition unit, and

a connection unit configured to establish a connection with the external device using the packet generated by the generation unit.

2. The communication device according to claim 1, further comprising:

a search unit configured to search for the service the network; and

a determination unit configured to determine a service that sets a predetermined priority to the packet,

wherein the recognition unit recognizes the service that set the predetermined priority, by the determination unit.

3. The communication device according to claim 2,

wherein the generation unit generates the packet to be transmitted to the external device based on the priority lower than the predetermined priority when no service is recognized by the recognition unit.

4. The communication device according to claim 1, wherein the recognition unit recognizes one of a deletion or an appearance of the service.

5. The communication device according to claim 1, further comprising:

a transmission unit configured to send the packet generated by the generation unit to the external device after the connection by the connection unit.

6. A method for controlling a communication device, the method comprising:

recognizing a service provided by a network;

generating a packet to be transmitted to an external device that provides the recognized service based on a priority set to the packet according to the recognized service, when the service is recognized, and

connecting with the external device using the generated packet.

7. A storage medium storing a computer-executable program for performing a method according to claim 6 when executed by a computer.
