摘要： [Problem]
The problem is to carry out the QoS control which tracks a change in a state of an outward line.
[Means for solving the problem]
A network repeater according to the present invention includes: a flow control means to carry out flow control for restricting inflow of a data flow which is received through an inward line; a bandwidth control means 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 monitoring means to monitor a change in a state of the outward line. In the 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 carried out on a condition corresponding to the specified condition.

摘要： The purpose of the present invention is to provide a line relaying device in which TDM line data is not discarded even if the transmission speed varies. Provided is a line relaying device (1) which is connected to opposing devices in a ring using variable-transmission-speed device-connecting lines (11, 12) (hereafter referred to as lines (11, 12)) in which the transmission speed varies, wherein, when a reduction in the transmission speed of the line (11) preset as the TDM line transfer route is detected by a device-connecting line termination unit (109), a mapping request, to which information indicating the amount of TDM-line bandwidth overflowing from the line (11) and a destination indicating the final line relaying device have been added, is generated by the mapping request processing unit (108), and transmitted via the other line (12) to another device connected in a ring network in order to map the overflow amount of bandwidth added to the mapping request on each line sequentially from the other device to the line relaying device as the final transfer destination, thereby forming a TDM-line detour route.
