A communication system includes: a communication apparatus; and a transmission apparatus configured to transmit a packet to be transmitted from the communication apparatus to a transmission destination, wherein the communication apparatus transmits, to the transmission apparatus, a first request signal for requesting a start of a communication with the transmission destination and a second request signal for requesting the start of the communication with the transmission destination with passing through the transmission apparatus, and wherein, when a request of the first request signal is permitted, the transmission apparatus notifies the communication apparatus of that a request of the second request signal is not permitted, and transmits the first request signal to the transmission destination, and the communication apparatus receives a response to the first request signal from the transmission destination and starts communication with the transmission destination without passing through the transmission apparatus. |
