Communication system, method for a communication system and controller for a communication system

A method for a communication system that includes a source node, one or more destination nodes, and a controller, the method comprising steps of:

• setting a logical connection between the source node and one or more destination nodes;
• notifying the source node and the one or more destination nodes of first information representing the logical connection and second information that is unique to the controller;
• dividing data to be transmitted to the one or more destination nodes into a plurality of segment data;
• transferring each of the segment data with the first and second information obtained from the controller from the source node to the one or more destination nodes;
• and
• storing each of the segment data in a receiving buffer of each of the one or more destination nodes.

A controller comprising:

• a control unit adapted to set a logical connection between a source node and one or more destination nodes,
• wherein the controller is adapted to notify the source node and one or more destination nodes of first information representing the logical connection and second information that is unique to the controller,
• wherein the source node is adapted to divide data to be transmitted to the one or more destination nodes into a plurality of segment data, and transfer each of the segment data with the first and second information obtained from the controller to the one or more destination nodes, and
• wherein each of the one or more destination nodes includes a receiving buffer and is adapted to store each of the segment data in the receiving buffer.
