Controller(s) can determine a control path towards each network switch using a novel controller-originated discovery process based on an in-band control network that is an overlay on the data network. The controller attempts to connect to each switch when it does not have a readily configured control connection towards the switch. Once the controller learns about the presence of a new switch and at least one or more paths to reach that switch through aforementioned discovery process, it can select, adjust and even optimize the control path's route towards that switch. During the controller-originated control network discovery process, the controller also learns about the to connectivity between all switches. Thereby, as a by-product of the discovery process, it uncovers the entire data network topology in parallel.

[PROBLEMS] To realize power saving of a receiver apparatus for receiving time-division multiplexed signals. [MEANS FOR SOLVING PROBLEMS] In the receiver apparatus, power is supplied to a receiver circuit in accordance with an operation start time. A signal is received through the receiver circuit, and a quality of the received signal is evaluated by a signal quality evaluation unit 109. Control is exercised to set a late operation start time if the quality of the received signal is good, and an early operation start time if the quality of the received signal is bad. In this way, a period for supplying power to the receiver circuit can be adjusted according to the quality of the received signal. This makes it unnecessary to fix, as in conventional techniques, a long power supply period in consideration of the case where the signal quality is bad. As a result, more power saving can be achieved.
