Device, system and method of maintaining connectivity over a virtual private network (VPN)

摘要

Some demonstrative embodiments include devices, systems and/or methods of maintaining connectivity over a Virtual-Private-Network (VPN). For example, a system may include a server to communicate with at least one computing device via a VPN tunnel, to receive from the computing device a mode indication indicating that the computing device is in a standby mode, to receive from at least one application server one or more packets intended for the computing device when the computing device is in the standby mode, based on at least one filtering criterion, to detect at least one targeted packet to be provided to the computing device, and to transfer the targeted packet to the computing device via the VPN tunnel.

1. A system comprising:
a Virtual-Private-Network (VPN) server to communicate with at least one computing device via a VPN tunnel, the VPN server configured to receive from said computing device a mode indication indicating that said computing device is in a standby power mode, the VPN server to receive from at least one application server one or more packets for said computing device when said computing device is in said standby power mode, said VPN server is configured to detect at least one targeted packet to be provided to said computing device based on at least one filtering criterion, the filtering criterion defining one or more attributes to trigger waking up the computing device from the standby power mode, said VPN server is configured to transfer said targeted packet to said computing device via said VPN tunnel, said VPN server is configured to send to said application server one or more messages indicating that said computing device is in an active power mode, when said computing device is in said standby power mode.
