[Conventional technology]

An example of a conventional method for collecting traffic data of this type is described in JP-A-7-147591. This traffic data collection method is divided into a time zone in which the traffic volume of the line is relatively large and a time zone in which the traffic traffic amount of the line is relatively small, and the traffic data collection cycle in the small time zone is a multiple of the traffic data collection cycle in the large time zone, and the time is small. When displaying the traffic data of the band, the accumulated traffic data is divided into multiples and displayed. In other words, divide the day into two time zones, a time zone with a relatively large amount of traffic and a time zone with a relatively small amount of traffic, and collect traffic data in a cycle of several times that in the time zone with a small amount of traffic compared to the time zone with a large amount of traffic. As a result, the amount of traffic data to be accumulated is reduced by reducing the number of times traffic data is collected.

[Problems to be Solved by the Invention]

However, this conventional technique has the following problems. The first problem is that traffic data in a small time zone has a long collection cycle, so the data during that cycle is averaged, and the traffic data at the peak time is not known, even if it is relatively small. If there is a big traffic in a short time, it cannot be detected. That is, the traffic data collection cycle is lengthened, the traffic amount for a long time is integrated, and when the traffic data is displayed, this average value is displayed. The second problem is that if the time zone with a large amount of traffic differs depending on the line, the time zone cannot be divided and the accumulated amount of traffic data cannot be reduced. The reason is that traffic data is often counted on a line-by-line basis, but the time zone with a lot of traffic may differ depending on the line, and the time zone with a relatively large amount of traffic on line A is from 9:00 to 17:00. However, the time zone with a relatively large amount of traffic on the B line may be different from 19:00 to 2:00 the next day, and the time zone with a relatively large amount of traffic cannot be determined, so it is relatively This is because the time zone when the amount of traffic is low is shortened. Therefore, an object of the present invention is to provide a traffic data collection device and a traffic data collection method that can grasp traffic data at peak times or for each time zone and reduce the transmission amount of the traffic data.

The first traffic data data collecting device of the present invention is used as long as the traffic data used for recognizing whether a congestion state has not occurred or whether the line equipment is appropriate is equal to or less than a predetermined threshold value. It is characterized in that it is not transmitted to the network management device. Further, the second traffic data collecting device of the present invention includes a threshold specifying means for the maintenance person to specify a threshold, a transmitting means for transmitting the threshold to the exchange, and a receiving means for receiving and storing the traffic data from the exchange. A network management device having a display means for displaying the accumulated traffic data, a counting means for counting the traffic of the line, a receiving means for receiving a threshold value from the network device, and a comparison between the received threshold value and the count value. The latter is characterized in that a switch having a transmission means for transmitting only large traffic data to the network management device is connected by a line. Further, the third traffic data collecting device of the present invention includes a threshold storage means for storing a threshold, a counting means for counting the traffic of the line, and the traffic data having a larger latter by comparing the threshold with the count value. A network management device having an exchange having a transmitting means for transmitting to a network management device, a receiving means for receiving and accumulating traffic data from the exchange, and a display means for displaying the accumulated traffic data is connected by a line. It is characterized by. Further, the traffic data collection method of the present invention includes a procedure for counting the traffic of the line, a procedure for reading the count value at a fixed cycle, a procedure for comparing the read count value with a predetermined threshold value, and a count value as a threshold value. It is characterized by having a procedure of setting only larger traffic data in the transmission area and a procedure of transmitting the traffic data set in the transmission area to the network management device after performing the above procedure for all traffic observation points. .. Traffic data is used to recognize whether there is a congestion condition and whether the line equipment is appropriate. Whether it is in a congested state or not, the traffic exceeds a certain value It can be judged whether or not the line equipment is appropriate, and if the line equipment is appropriate or less than a certain value, it can be judged that the equipment is excessive. From this, if it is known that the traffic data below a certain value is below a certain value, the value is unnecessary. Therefore, the present invention is designed to reduce the transmission of unnecessary traffic data to the network management system by comparing the traffic data with the threshold value and providing a process for not transmitting the traffic data below the threshold value to the network management system. Is. In this way, it is possible to reduce the amount of traffic data collected by the network management system.

Each of these means operates as follows. The threshold value designating means 11 stores the threshold value specified by the maintenance person. The transmission means 12 transmits the threshold value stored in the threshold value designating means 11 to the exchange 2. The receiving means 22 receives and stores the threshold value transmitted by the transmitting means 12. The counting means 21 counts the traffic of all the traffic observation points. The transmitting means 23 compares the traffic data counted by the counting means 21 with the threshold value stored in the receiving means 22, and transmits the traffic data larger than the threshold value to the network management device 1.

First, when the maintenance person specifies the threshold value by the threshold value designating means 11, the network management device 1 stores the designated threshold value. Next, the transmission means 12 transmits the threshold value of the traffic data from the network management device 1 to the switch 2 (sequence S1 in FIG. 2). The exchange 2 that has received the traffic data threshold value by the receiving means 22 returns a reception confirmation to the network management device 1 and stores the received threshold value (sequence S2).

As a result, if the count value is larger than the threshold value, the read traffic data is set in the transmission area (step A4 in FIG. 1), and if it is not large, nothing is done and the traffic data of the next traffic observation point is counted from the counting means 21. read out. If the traffic data is read and processed for all the traffic observation points (step A1 in FIG. 1), the traffic data set in the transmission area is transmitted to the network management device 1 (step A5 in FIG. 1 and sequence S3 in FIG. 2). ). When the network management device 1 receives the traffic data by the receiving means 13, the network management device 1 returns the reception confirmation to the exchange (sequence S4 in FIG. 2). Finally, the display means 14 reads out the accumulated traffic data, and if there is no traffic data, the display means uniformly displays that the traffic is below the threshold value as the traffic below the threshold value.
