Abstract
A communication device includes a processor that is operative to perform actions, including, determining whether a failure occurs in a regular communication channel to transmit a packet to another communication device, selecting, upon determining that the failure occurs in the regular communication channel, a backup communication channel for transmitting the packet, determining, upon selecting the backup communication channel, whether the backup communication channel is shared by the regular communication channel and another regular communication channel, changing, upon determining that the backup communication channel is shared, a priority assigned to the packet transmitted from the regular communication channel to the backup communication channel, and controlling the transmission of the packet in accordance with the changed priority.
