摘要： A transmission apparatus transmits/receives test frames to test connectivity between the transmission apparatus and another transmission apparatus to/from the other transmission apparatus at regular intervals. The transmission apparatus includes a frame length changing unit that changes a frame length, which is capacity of each of the test frames, at every transmission when the test frames are transmitted to the other transmission apparatus at the regular intervals; a reception determining unit that determines whether the test frames having changed frame lengths transmitted from the other transmission apparatus at the regular intervals have been received at the regular intervals; and a frame length calculating unit that calculates the frame length of the test frame that has not been received if the reception determining unit determines that the test frame has not been received.

摘要： The central apparatus obtains the destination information of a plurality of terminal devices, generates one request packet consolidating the obtained plural destination information, and transmits the generated one request packet. The relay unit receives one request packet, generates a plurality of request packets on the basis of the consolidated destination information, and transmits the generated request packet. The relay unit receives reply packets from a plurality of terminal devices, generates one reply packet consolidating the destination information of the transmission origins of the received plural reply packets, and transmits them to the central apparatus. The central apparatus receives the returned one reply packet and determines continuation and blockade of the network connection for each terminal device.

摘要： A check-frame receiving unit receives a check frame containing bandwidth data of a bandwidth allocated to a communication between a transmitting side and a receiving side. A bandwidth-data extracting unit extracts bandwidth data in the check frame and outputs a received bandwidth with a MAC address in the check frame. A bandwidth comparing unit reads out preset bandwidth set in association with a destination MAC address from a bandwidth storing unit, and compares the received bandwidth with the preset bandwidth. A response-frame generating unit generates a response frame containing a result obtained by comparing the received bandwidth with the preset bandwidth, the received bandwidth, and the preset bandwidth. A response-frame transmitting unit transmits the response frame generated by the response-frame generating unit.

摘要： A method of controlling the communication rate between a user terminal and an edge switch of a network is provided. This method includes the step of matching the transmission rate at which data is transmitted from the user terminal to the edge switch, with the communication rate of the edge switch that is determined under contract with a user.
