ABSTRACT:
An integrated multimedia network system is constructed by a plurality of transport nodes each having several types of communication media intervened at arbitrary locations in a ring-shaped transmission path. One transport node exchanges communication information of communication media in a fixed-length packet transfer format. The transport node has a packet switcher, which divides packets into plural groups for at least self node and other nodes by switching between media communication packets from the self node and those packets from an adjoining transport node based on header information that indicates their destinations. A group of packet communication information destined to the self node is sent to the associated communication medium. A group of packets for other nodes is time-divisionally multiplexed and is sent on the transmission path. The packet switcher is supplied with a time-divided multiplexing signal from an adjoining transport node to be sent over the transmission path after the signal is time-divisionally separated for each group.
