Abstract
This invention constructs within the LAN a private area network (PAN) which is configured by terminal devices (personal computers and the like) of a specific group, is hardly influenced by the LAN traffic, and has high security. For this purpose, a PAN server which manages the communication route between specific terminals is installed within the LAN. The PAN server sets the communication route of each terminal device as label information, and causes switches and terminals to set pieces of label information generated for them. When the frame of data from a given port of each connection switch contains information representing PAN communication, the connection switch outputs the data to only a port specified by routing label information described in the frame.
