<p><P>PROBLEM TO BE SOLVED: To enable high-speed packet switching at the time of failure, even in a broadband network. <P>SOLUTION: A packet processing apparatus includes a plurality of IF units each connected with a counter apparatus via a work path or a protection path and an SW connecting the plurality of IF units via a data bus. When a packet sent from the counter apparatus is received by any one of the plurality of IF units, the packet processing apparatus determines whether the packet is a monitoring packet monitoring a connection state with the counter apparatus. When it is determined that the packet is a monitoring packet, the packet processing apparatus uses the data bus via the SW to transmit the monitoring packet to the plurality of IF units. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
