Abstract

PROBLEM TO BE SOLVED: To regulate and control traffic with respect to a time band of a high load by estimating traffic on a communication network system, calculating date and time band of coming into a system overload state and regulate and control the traffic quantity so as to previously suppress the system overload state. SOLUTION: Traffic quantity transition sets a traffic regulating ratio, etc., by a traffic measurement/regulation ratio set point. Since the transition of a traffic quantity becomes lower than a system overload boundary by starting traffic regulation and control at a traffic regulation and control starting time, a communication network system will not be congested. Since the increase in the traffic quantity tends to grow at the traffic measurement/regulation ratio set point, traffic regulation rate and the like are set and executed.

Reference numeral 8 denotes a traffic regulation control end time for terminating the traffic regulation control. 9 monitors at appropriate time intervals during the period of traffic regulation control,
It is a traffic monitoring point that performs traffic regulation control according to the current situation.

Next, referring to the traffic volume transition model diagram in FIG. 1, the traffic volume transition is in a state before the traffic restriction control, a state in which the traffic restriction control is not performed during the traffic restriction control period, and a traffic network in which the traffic restriction control is performed. The state of monitoring the system will be described.

The elapsed time before the traffic regulation control, that is, the transition of the traffic volume from t = 0 to t = t2 is represented by traffic volume transitions 2a, 3a and 4a. this house,
In the traffic amount transition 2a, the growth of the traffic amount tends to increase rapidly at t = t1, and when the regulation control is not started at t = t2, the period from t = t2 to t = t3 is:
It is presumed that the traffic volume transition is as shown in FIG. Therefore, the communication network system becomes congested beyond the system overload boundary line 7, which is not preferable.

Next, a case where the traffic regulation control is performed on the traffic volume transition 2a from the traffic regulation control start time 6 will be described.

The traffic volume transition 2a is based on traffic measurement
The traffic regulation rate and the like are set at the regulation rate setting point 5a (t = t1), and the traffic regulation control start time 6 (t =
By starting the traffic regulation control at t2), the transition of the traffic volume becomes like the traffic volume transition 2b,

Specify the interval T (Step S10)
3). The specification of the traffic regulation rate is set by referring to a predetermined traffic regulation rate database. At that time, the traffic regulation rate is calculated appropriately.
Furthermore, it is more effective to specify these traffic regulation rates as a function of the monitoring time as well as to set a constant value throughout the regulation date and time and time zone.

When the traffic regulation control is started, the traffic of the communication network system is monitored at the traffic monitoring point 9 at each monitoring time interval T, and the traffic regulation control according to the current traffic situation is executed (step S105). In this case, all monitoring time intervals T may or may not be equal.

Next, it is determined whether or not it is the traffic regulation control end time 8 (step S106). Step S
If the determination result in 106 is YES, the process ends. Also,
If the decision result in the step S106 is NO, a step S is executed.
Returning to 105, the traffic of the communication network system is monitored at the specified monitoring time interval T.
