If data packet is in priority to be transmitted to the corresponding output port(208), data packet is duplicated ad transmitted to bottom nodes in case that the number of allowable credit to the corresponding bottom node is larger than 0(209). If the current node is the final receiver(205), packets are transmitted to an application layer and counter is increased by 1(206). If the counted value becomes a reference counter of flow control and a double number of credit update unit(211), the current node decides the amount of packets receivable from the top node based on the size of virtual buffer to each bottom node and generates credit packets including related information to the top node(213).
