- 摘要:
- <p><P>PROBLEM TO BE SOLVED: To construct within a LAN a particular area network (PAN) which is composed of terminal apparatuses (personal computers or the like) of a specific group, is little influenced by LAN traffic and has high security. <P>SOLUTION: A PAN server for managing a path of communications between specific terminals is installed within the LAN. The PAN server sets the communication path of terminal devices as label information and causes each switch and each terminal to set label information generated therefor. When information indicating PAN communication is present in a frame of data from a certain port of each connection switch, the connection switch outputs the information only to a port specified by path label information described in the frame. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p>
