The packet switching system is designed for transmitting and receiving packets via a packet switching network. It comprises multiple routing tables, each generated by a unique routing policy, and stored in routing apparatuses deployed at various points in the network. An identifier is inserted in the packet to specify the routing tables, and an identifier changer modifies the value of this identifier on the network. The routing apparatus selects one of the routing tables based on the identifier in the received packet and transfers the packet to the specified destination.
Another notable patent is a communications system that allows data transfer without using a terminal ID assigned by an access network. Instead, it utilizes routing information distinct from the terminal ID. This system transmits data from a first terminal to a second terminal via multiple transfer devices, ensuring efficient data routing.
