DATA REPEATER AND REPEAT DATA CONTROL METHOD, AND COMPUTER PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a device and a method which can further efficiently execute data repeat processing in a data repeater.

SOLUTION: The data repeater is so constituted that data repeat control further reflecting a data storage state can be realized by acquiring the data storage state of a data storage means as queue length distribution information, and by deciding congestion control processing modes such as packet discard and ECN (explicit congestion notification) bit settings according to the queue length distribution information. The congestion control mechanism is actuated from a state prior to a state that a network becomes in a congestion state. High network utilization efficiency can be maintained even if the traffic is in a congestion state differently from the control on the basis of the averaged queue length such as conventional RED (random early detection) in which processing such as excessive packet discard is executed.
