Abstract: An apparatus controls a transmission interval of maintenance packets in a communication network. The apparatus calculates, within a first bandwidth available for the transmission and reception of packets, a second bandwidth that is free in the apparatus and usable for transmitting and receiving the maintenance packets for maintenance of the communication network. The apparatus determines a transmission interval of maintenance packets in accordance with the calculated second bandwidth and transmits the maintenance packets to another apparatus in the communication network at the determined transmission interval.

Abstract: In a load testing system, a transmission device measures a bandwidth of user data transmitted from a user terminal in real time, calculates a calculation bandwidth by subtracting the bandwidth of the user data from an evaluation bandwidth preset to evaluate the performance of a network, and transmits test data corresponding to the calculation bandwidth with the user data corresponding to the bandwidth of the user data. A reception device receives the user data and the test data transmitted with the user data, and evaluates the performance of the network based on the user data and test data.

Abstract: A network has communication apparatuses communicatively interconnected in compliance with a maintenance protocol. An LBM frame transmission unit transmits an LBM frame to the network. An MEP information acquisition unit identifies a communication apparatus having transmitted an LBR frame as an MEP when the LBR frame is received, and acquires MEP information from the LBR frame. An LTM frame transmission unit transmits an LTM frame to the MEP identified by the MEP information acquisition unit. An MIP information acquisition unit identifies a communication apparatus as an MIP from an LTR frame when the LTR frame is received as a response to the LTM frame, and acquires MIP information indicating information about the MIP. A topology information generation unit generates topology information representing a configuration of the network from the MEP information acquired by the MEP information acquisition unit and the MIP information acquired by the MIP information acquisition unit.
