Abstract:
In an IEEE1394 serial bus network having a plurality of nodes interconnected via an IEEE1394 cable, a method for performing a protocol interfacing operation for said nodes, comprising the steps of:a) formatting a protocol identifier packet of each of said nodes upon initializing an IEEE1394 serial bus due to node addition or deletion; b) sending the formatted protocol identifier packet of each of said nodes to the other nodes; c) storing said protocol identifier packets of said nodes into a protocol map under control of a bus manager; d) sending a protocol query packet including a target node identifier from a source node among said nodes to said bus manager to request the transfer of data; and e) retrieving a communication protocol from said protocol map and sending a protocol set packet including information about the retrieved communication protocol from said bus manager to said source node and a target node among said nodes to perform the transfer of data between said source and target nodes through said communication protocol.
