System for rebooting relay apparatus based on detection of completely no communication establishment data presence
A relay apparatus enables automatic execution of the reboot process after a controller has detected a discontinuance of data. Accordingly, data in a communication is reliably prevented from destruction. Moreover, the reboot process can be achieved with simple operations. In addition, an operator is allowed to finish operations for changing the configuration of the relay apparatus, for example, before the data communications have actually been discontinued. The operator can finish the operation within the business hours. A burden of the operator can be lightened.
1. A relay apparatus comprising:
a communication controller designed to relay data for communication, the communication controller providing communication establishment data specifying establishment of each communication; and
a controller montoring presence of the communication establishment data when the controller receives a signal requesting start of a reboot process, the controller executing the reboot process when the controller detects completely no communication establishment data.
2. The relay apparatus according to claim 1 , wherein said controller transmits a signal notifying execution of said reboot process.
3. The relay apparatus according to claim 1 , wherein said controller holds the reboot process when it detects the communication establishment data, and said controller executing the reboot process when it detects no communication establishment data after it has held the reboot process.
4. A method of rebooting in a relay apparatus, comprising:
monitoring presence of communication establishment data specifying establishment of each communication in the relay apparatus when a controller receives a signal requesting start of a reboot process; and
executing the reboot process when the controller detects completely no communication establishment data.
5. The method according to claim 4 , further comprising transmitting a signal notifying an execution of said reboot process.
6. The method according to claim 4 , further comprising:
holding execution of the reboot process when the communication establishment data is detected; and
continuing to monitor the presence of the communication establishment data.
7. A computer-readable storage medium containing program instructions for causing a relay apparatus to:
monitor the presence of communication establishment data specifying establishment of each communication in the relay apparatus when a controller receives a signal requesting start of a reboot process; and
execute the reboot process of the relay apparatus when the controller detects completely no communication establishment data in the relay apparatus.
8. The computer-readable storage medium according to claim 7 , further causing the relay apparatus to transmit a signal notifying execution of said reboot process to a terminal from the relay apparatus through a wireless communication network.
9. The computer-readable storage medium according to claim 7 , further causing the relay apparatus to:
hold execution of the reboot process when the comnmnication establishment data is detected in the relay apparatus; and
continuing to monitor for the presence of the communication establishment data.
