In a switch system including a plurality of switch mechanisms that form a ring topology, each of the switch mechanisms includes an input and output unit that inputs and outputs a packet to and from an outside of a loop; and a gate unit that transmits transmission information including whether there is a packet to be received by one of the switch mechanisms set as a following stage in the loop to the following stage in the loop at predetermined time's intervals. The input and output unit accumulates the packet input from the outside of the loop, and generate transmission information on the accumulated packet. The gate unit transmits the packet accumulated in the input and output unit and the transmission information on the accumulated packet to the following stage in the loop when receiving transmission information, from one of the switch mechanisms set as a preceding stage in the loop, indicating that there is not a packet to receive.
