Document Type and Number:
Japanese Patent JP5762106
Kind Code:
B2
Abstract:
A communication apparatus that is capable of enabling communication even when IPsec life time information is taken over. The communication apparatus is connected to a network via a network interface device and operates in a first power mode or a second power mode with less power consumption. A notification unit notifies the network interface device of IPsec life time information when shifting to the second power mode from the first power mode. A storage unit stores first time information showing time of shifting to the second power mode from the first power mode. An acquisition unit acquires the life time information from the network interface device when shifting to the first power mode from the second power mode. A correction unit corrects the life time information based on second time information showing time of shifting to the first power mode from the second power mode and the first time information.
