ABSTRACT:
The packet switching system for transmitting and receiving a packet via a packet switching network100, which comprises a plurality of routing tables (#0, #1, #2. . . ), each of which has been generated by a unique routing policy, stored in the routing apparatuses deployed at the border, at the origin or at the end of the respective routing domains, an identifier (RTI) inserted in the packet to specify the routing tables, and an identifier changer to change a value of the identifier on the packet switching network100. The routing apparatus selects one of the routing tables (#0, #1, #2. . . ) according to the RTI in the received packet and transfers the packet to a destination that is specified by the selected routing table.
