Patent ID: 8149873

Claim:
A data transmission apparatus of a plurality of data transmission apparatuses on a network, the data transmission apparatus comprising: a disconnecting device operative for disconnecting a number being at least one but not all of a plurality of sequence connections established between transmission plugs of a transmitting node and reception plugs of a receiving node, both nodes being connected to the network wherein the transmission plugs and reception plugs are operative for transmission and reception of a plurality of sequences in one isochronous stream; an optimization requesting device operative for requesting optimization of transmitting sequences to the transmitting node for transmission to the receiving node via the plurality of sequence connections reduced by the number of disconnected sequence connections; a receiver operative for receiving information about at least one of the transmission plugs newly assigned to a transmitting sequence used by the transmitting node of which the at least one of the plurality of sequence connections has been disconnected by the disconnecting device, the information being received as an answer for the optimization request from the transmitting node; and a connecting device operative for establishing at least one new sequence connection between the at least one newly assigned transmission plug and at least one of the reception plugs of the receiving node of which the at least one of the sequence connections has been disconnected by the disconnecting device.
