摘要： A GW (PDG) at the termination of remote access is installed in the 3GPP system. After an IPSec tunnel between a terminal and the GW is opened, an IPSec tunnel between a VPN client and the corporate network GW is opened, whereby the data from the terminal is transferred via two tunnels between the terminal and the GW and between the VPN client and the corporate network GW to the corporate network. Also, the GW checks if the destination network uses the global address from the destination IP address of a message received from the terminal making the remote VPN access. If the global address is required, the source IP address of the message received from the terminal is translated from the private address for use within the corporate network to which the terminal is allocated to the global address to transfer the message.

摘要： A control node includes: a monitoring packet transmission section for transmitting a monitoring packet; a monitoring packet reception section for receiving a monitoring packet; an adjustment section for selecting a redundant node from a non-control nodes; a packet generation section for generating a setup packet for specifying the redundant node out of the non-control nodes in accordance with information about the redundant node selected by the adjustment section; and a packet transmission section for transmitting the setup packet to the non-control node. The non-control node includes a control section that acquires information about the traffic upon receiving the monitoring packet, transmits a monitoring packet after acquisition of the traffic, and specifies the non-control node as the redundant node based on information about the redundant node contained in the setup packet upon receiving the setup packet.
