Abstract:
1. A relay apparatus for relaying a packet to be transmitted in radio communication by at least one wireless terminal in a communication area, comprising: a packet monitoring part for obtaining data on a bandwidth used in the radio communication by the wireless terminal from the packet to be relayed by the relay apparatus; a bandwidth managing part for calculating and recording a total bandwidth in use used for the radio communication by the wireless terminal in the communication area based on the data obtained by the packet monitoring part; a retransmission adjusting part for determining an upper limit of a packet retransmission number in accordance with an amount of an available bandwidth obtained by excluding the total bandwidth in use from a maximum bandwidth available in the radio communication by the wireless terminal; and a retransmitting part for retransmitting a packet whose transmission has ended in failure by the relay apparatus, in a range not exceeding the upper limit of the packet retransmission number determined by the retransmission adjusting part.
