Abstract
A packet transfer processing device includes common processing units that perform processing common to inbound processing of a packet received from an access network for transfer to a core network and outbound processing of a packet received from the core network for transfer to the access network, an input destination switching unit that selects common processing units to which the received packets are to be input, an output destination switching unit that outputs packets processed by the common processing units to a destination network, an individual processing switching unit that selects a common processing unit to connect to an individual processing unit that performs individual processing not performed by the common processing units as part of inbound processing, and a control unit that controls the input destination switching unit, the individual processing switching unit, and switching supply/shutoff of power to the common processing units.
