Abstract

ABSTRACT OF THE DISCLOSURE
In a packet network which includes a plurality of packet switching stations and in which a packet including in its header portion a VPI (Virtual Path Identifier) for identifying one of logical paths multipliexed on a transmission line and a VCI (Virtual Connection Identifier) for identifying one of logical connections multiplexed on one logical path is com-municated between the switching stations, each switching station preliminarily designates a VCI to be given to a packet directed to that station when a logical con-nection is to be set up between that station and another station. When receiving an information packet from the other station, the each station makes access to header label conversion tables on the basis of a VCI included in the received packet to read internal routing infor-mation necessary for a packet switching operation and a VCI to be given to a packet to be delviered.
