Abstract
In order to provide a redundancy configuration to an access gateway apparatus in which a control plane and a user plane are separated, the access gateway apparatus includes: a control computer for receiving control signals from the networks to establish the communication path, thereby determining packet transfer information for the data; and a transfer computer for receiving the packet transfer information from the control computer to transfer the data through the communication path. The transfer computer includes: a plurality of first transfer computers for executing the transfer of the data; and a second transfer computer for taking over, when a fault occurs in any one of the plurality of first transfer computers. The control computer includes: a first control computer for processing the control signals received from the networks; and a second control computer for taking over, when a fault occurs in the first control computer.
