PROBLEM TO BE SOLVED: To effectively improve the transmission speed and stability of a communication apparatus in which two or more communication links can be concurrently used by taking into consideration the operation in a level of packet to be transmitted.SOLUTION: The lowest indications of consecutive packets favorable for transmission in first and second communication links are stored as the first and second adequate numbers. One or more packet is created as a transmission packet, and the number is counted and compared with the first and second adequate numbers. When the counted number is equal to or less than any of the first and second adequate numbers, one of the first and second communication links is selected as a communication link. When the counted number is over one of the first and second adequate numbers, and equal to or less than the other adequate number, a communication link to which the other adequate number is assigned is selected. When the counted number is over both the first and second adequate numbers, and less than the sum of the first and second adequate numbers, a communication link to which the other adequate number is assigned, or both the first and second communication links are selected. When the counted number is equal to or more than the sum of the first and second adequate numbers, both the first and second communication links are selected. |
