COMMUNICATION SYSTEM, COMMUNICATION METHOD, AND TRANSMISSION APPARATUS
First Claim
1. A communication system, comprising:
- a communication apparatus configured to generate a first request signal and a second request signal, each requesting a start of a communication with a transmission destination; and
a transmission apparatus configured to transmit a packet to be transmitted from the communication apparatus to the transmission destination,wherein the communication apparatus transmits the first request signal and the second request signal to the transmission apparatus, the second request signal requesting the start of the communication with the transmission destination with passing through the transmission apparatus, andwherein, 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, andthe 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.

5. A communication method in a communication system including a communication apparatus communicating with a transmission destination and a transmission apparatus transmitting a packet transmitted from the communication apparatus to the transmission destination, the communication method comprising:
-
transmitting, to the transmission apparatus, a first request signal for requesting a start of the communication with the transmission destination and a second request signal for requesting a start of the communication with the transmission destination with passing through the transmission apparatus, by the communication apparatus; when a request of the first request signal is permitted, notifying the communication apparatus of that a request of the second request signal is not permitted and transmitting the first request signal to the transmission destination, by the transmission apparatus; and receiving a response to the first request signal from the transmission destination with respect to the first request signal and starting communication with the transmission destination without passing through the transmission apparatus, by the communication apparatus.

6. A transmission apparatus configured to transmit a packet to be transmitted to a transmission destination from a communication apparatus configured to communicate with the transmission destination, the transmission apparatus comprising:
-
a communication unit configured to receive a first request signal for requesting a start of the communication with the transmission destination and a second request signal for requesting a start of the communication with the transmission destination with passing through the transmission apparatus, each of the first request signal and the second request signal being transmitted from the communication apparatus; and a controller configured to notify the communication apparatus of that a request of the second request signal is not permitted and controls the first request signal to be transmitted to the transmission destination, when the communication apparatus communicates with the transmission destination based on a request of the first request signal.
