Abstract:
1. A network repeater, comprising: a flow controller configured to carry out flow control for restricting inflow of a data flow which is received through an inward line; a bandwidth controller configured to carry out bandwidth control of controlling a bandwidth of a data flow which is received through the inward line and is sent through an outward line; and an outward line monitor configured to monitor a change in a state of the outward line, wherein in a case that the monitored state of the outward line satisfies a specified condition which is determined in advance, either the flow control or the bandwidth control is configured to be carried out on a condition corresponding to the specified condition, wherein the outward line monitor is an inter-apparatus line terminating unit configured to monitor a transmission speed on an inter-apparatus line comprising a wireless line whose transmission speed is changed due to an external environment, and which, when the transmission speed on the inter-apparatus line is changed to a predetermined value, is configured to notify a Quality of Service (QoS) controller of changed transmission speed information, and wherein the QoS controller comprises a QoS information table configured to store parameter information on QoS control which is predetermined correspondingly to the predetermined transmission speed on the inter-apparatus line, and to read the parameter information on the QoS control, which is predetermined correspondingly to the transmission speed indicated by the transmission speed information, from the QoS information table when receiving notice regarding the changed transmission speed information on the inter-apparatus line from the inter-apparatus line terminating unit.
