Transmission device and transmission method

摘要

A transmission device includes a temporary storage unit that is provided for each port receiving input data, stores the data temporarily, and outputs the temporarily stored data in response to a read enable signal, a storage unit that performs time-division multiplexing on the data output from the temporary storage unit in response to the read enable signal and stores the data, a flow monitoring unit that monitors a data flow for each of the ports, and a control unit that selects a temporary storage unit that is a read enable target from the temporary storage units corresponding to the ports to which the data is input, by a weighted round robin system in accordance with the data flow for each of the ports, and outputs the read enable signal to the selected temporary storage unit.

1. A transmission device comprising:
temporary storage units that are provided for each port receiving input data, store the data temporarily, and output the temporarily stored data in response to a read enable signal; a storage unit that performs time-division multiplexing on the data output from the temporary storage units in response to the read enable signal and stores the data; a flow monitoring unit that monitors a data flow for each of the ports; and a control unit that selects a temporary storage unit that is a read enable target from the temporary storage units corresponding to the ports to which the data is input, by a weighted round robin system in accordance with the data flow for each of the ports, and outputs the read enable signal to the selected temporary storage unit, wherein the control unit assiqns weight according to the weighted round robin system to the temporary storage unit that is the read enable target in accordance with a data flow for each of the ports and selects the temporary storage unit in descending order of the weight.
