<p>PURPOSE:To efficiently perform packet switching by enabling packet mutual multiple address communication to be performed between plural terminals call- connected by a virtual terminal and a virtual call, by setting a packet multiple address communication equipment in a packet switching network as the virtual terminal. CONSTITUTION:A data packet as a first input received from a reception terminal 108 in the packet multiple address communication equipment 101 is sent to a reception packet holding device 104 allocated corresponding to a logic channel by a packet multiplexing communication equipment 102. The reception packet holding device 104 searches a delimiter code set in advance in user data in the date packet, and when no code is detected, it is registered at a queue. When the data packet having the delimiter code is received, it is sent to a duplication packet generating device 105 with the data packet held until then. The duplication packet generating device 105 arranges duplication packets to other logic channels in communicating, and supplies them to the packet multiplexing communication equipment 102 via a connection line 107.</p> |
