A method to prevent net update oscillation

The invention claims a preventing the bus connecting to generate method for network updating vibration and a plurality of racing part network information updating, wherein the method comprises the following steps: (a) by a wire port is coordinator wherein the local bus; And the specific port is a coordinator of moving up and step (b) (i), otherwise moving up and step (b) (II); (b) (i) by the wire port on the local bus wherein discovered the network updating, conflictA discovering network updating conflict a moving up and step (c); (b) (II) determining whether the wire port received from one of the local bus mediator's a UPDATE_ROIMS information on network,A receiving UPDATE_ROUTE information of moving up and step (c); (c) updating a global network with a process fixing Piece is 1; (d) updating Piece through the network determining whether is arranged is 1 data steps (c) is a process is carried out; successfully(e) executing one of the following steps: a i (u1) successful to updating a deletion the network in steps (d) and step (c) is process; And (II) formed by IEEE 1394.1) standards the network updating, network updating Piece is 0.
