Abstract
In a packet switching system made up of a single or a plurality of switching nodes or local units each including a label conversion unit for accommodating a plurality of packet circuits and performing conversion into output port information of a switch on the basis of a logic channel on a packet circuit, a self-routing switch for performing switching on the basis of the output port information, and a control unit for terminating a control packet and performing the call processing function, and a switching node or tandem unit including a single or a plurality of self-routing switches for interconnecting the local units, there are provided a device for setting, between the tandem unit and a destination-side local unit, the same logic channel as that between an originating, side local unit operative for information transfer and the tandem unit in respect of a call destined for a local unit other than this local unit and a device, operable in the originating-side local unit for information transfer, for inserting output port information of the self-routing switch inside the tandem unit into a packet destined for the local unit other than this local unit, whereby in the tandem unit, set…
