System and method for reliable real-time communications among a plurality of nodes having functions conforming to IEEE-1394 serial bus and participating in a session of sharing the maximum bandwidth

摘要

A data communication method allowing reliable real-time communications among a plurality of nodes participating in a session is disclosed. In the case where a plurality of nodes participate in a session such that two or more nodes do not concurrently send data, a session management node reserves a necessary bandwidth needed by all the nodes participating in the session by accessing the Isochronous Resource Manager.
