Figure 2 is a block diagram showing the connection form for each service of the Internet service subscribers according to the present invention.

The present invention relates to a method for calculating traffic charged per subscriber per Internet service for Internet network design, and more specifically, to calculate the busy hour traffic of the entire network through prior analysis, and using the calculated busy hour traffic of the entire network. The present invention relates to a method of calculating traffic charged per subscriber for each Internet service for designing a network by calculating the traffic charged per subscriber per Internet service.

The internet network is a network that provides various services such as voice, high speed data, and multimedia service, and has a bursty traffic characteristic.

Accurately charged traffic calculation and design is important for economically building a network while minimizing packet loss or delay for such bursty traffic subscribers.

The general network design method calculates the charged traffic per node based on the busy data and calculates node capacity and link capacity according to design criteria.

Busy hour means the time when the traffic is the highest among 24 hours a day, and calculates the traffic charged per subscriber for each internet service and calculates the traffic of each node by calculating the sum of traffic charged per subscriber for each internet service. Computing node capacity and link capacity is a common method of Internet network design.

However, this method has a problem in that the facility is over-invested by applying the busy hour for each Internet service because the busy hour time for each service is different and the excess traffic is calculated more than the traffic amount imposed on the actual network.

In order to solve the above problems, an object of the present invention is to calculate the traffic charged per subscriber for each Internet service by applying the busy time traffic of the entire network.

To this end, the method of calculating the traffic charged per subscriber per Internet service for the Internet network design according to the present invention includes a first method of connecting subscribers who use a service according to an internet network access method of an internet service to an internet network using an ADSL method. A first step of dividing the group into a second group connecting to the Internet network using a dedicated line, and a third group connecting to the Internet network using dial-up; A second step of calculating a time zone with the most traffic every month in the main network of the Internet network and defining it as the network busy hour; Calculate the total traffic generated by the first group at busy times, predict ADSL total traffic in the design year through regression analysis, and then estimate the total traffic generated by the first group at busy times. A third step of calculating the traffic charged per subscriber of the first group by dividing by the number of subscribers in the year; Dividing the subscribers of the second group by the speed and the configuration of the leased lines, calculating the average utilization rate of the leased lines of the second group at the time of network busy, and then calculating the charged traffic per subscriber of the second group; And a fifth process of calculating the charged traffic per subscriber of the third group using the number of dialup service subscribers and the average utilization rate of the design year after obtaining the required number of dialup lines.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a flowchart illustrating a process of calculating traffic charged per subscriber per Internet service for designing an Internet network according to the present invention.

First, various Internet services are classified by access method and subscriber characteristics.

In the present invention, it is divided into three groups as shown in Figure 2 (S110).

First, a subscriber group 21 accessing the Internet network 20 using an Asymmetric Digital Subscriber Line (ADSL) method, and second, a subscriber group 23 accessing the Internet network 20 using a leased line. Third, it is divided into a subscriber group 22 that accesses the Internet network 20 by dial-up through an existing Public Switched Telephone Network (PSTN) or Integrated Services Digital Network (ISDN) 17.                     

In addition, the ADSL subscriber stations 11 and 12 are connected to the Internet network 20 through the DSL Access Multiplexer (DSLAM) 15 and the Network Access Server (NAS) 16, and the dial-up subscriber terminal 13 is connected. Is connected to the Internet network 20 through a Remote Access Server (RAS) 18 via a PSTN or ISDN 17 network, and the dedicated line subscriber station 14 is connected to the Internet network 20 through a subscriber router 19. ) Is connected.

As described above, after classifying the Internet service into three, it is defined as the network busy time by extracting the hourly traffic volume of the main network every month (S120).

Here, the main backbone network refers to a network composed of nodes directly connected to a node having an access point (an Internet service provider (ISP), an overseas point-of-presence (POP), a server, etc.).

In addition, the charging traffic per subscriber of the ADSL subscriber group is calculated every month at the busy time (S130).

To do this, we calculate the total amount of traffic collected from routers (or network access devices) that accept ADSL subscribers, and calculate the monthly average traffic of the busiest hour of the month.

If it is not possible to collect the traffic of all ADSL routers, sample the main nodes to collect the traffic, and replace the average value of the month of the sample network with the population value.

For the design of the Internet network, it is important to accurately predict the traffic of the design year. Therefore, the traffic of the ADSL service of the specific month of the design year is searched by regression of the calculated monthly average traffic of the busy hour of the month. Estimate the value.

The charged traffic per subscriber of the ADSL subscriber group is calculated by Equation 1 using the estimated traffic value of the ADSL service and the demand predicted ADSL service subscriber information.

<Equation 1>

Traffic charged per subscriber = Total traffic / subscribers in ADSL subscriber group

After calculating the charged traffic per subscriber of the ADSL subscriber group, the average utilization rate for each speed of the leased line subscriber group and the charged traffic per subscriber are calculated (S140).

A dedicated line subscriber group is a group that uses internet service using a fixed speed to the internet network node. It can be divided into various types according to the subscription speed and the LAN configuration method of the subscriber side. A subscriber may be divided into a group having a structure in which subscribers are mapped one-to-one and a group having a structure in which circuits and subscribers are mapped in a one-to-many configuration, and may be subdivided again according to a subscription speed.

In order to calculate the charged traffic of the dedicated line subscribers, the traffic of the dedicated line subscriber routers is collected.

After subdividing leased line subscribers by subscription speed and configuration method, we calculate the average monthly traffic volume of the busy times calculated above.

Then, the traffic volume is divided by the subscription rate to calculate the average utilization rate for each rate.

Like the ADSL subscriber group, the regression analysis of the design traffic of the leased line subscriber group in the design year is used to predict the average utilization rate by leased line speed, and the leased line subscriber group is expressed by Equation 2 using the forecasted leased line subscriber demand by the speed at the design time. Calculate the traffic charged per subscriber.

<Equation 2>

Traffic charged per subscriber = (subscription rate × average utilization by rate) / number of subscribers

In this case, the principle of guaranteeing the quality as much as the speed of the subscription to the subscribers of the leased line, but to ensure the quality of the speed of the subscription to the subscribers, the network operator is designed to construct the network economically and make the most of the bandwidth. A more efficient way is to design a margin with the amount of traffic used by the subscribers of the leased line.

After calculating the charged traffic per subscriber of the dedicated line subscribers, the charged traffic per subscriber of the dial-up subscriber group is calculated (S150).

The dial-up subscriber group calculates the number of circuits required between the PSTN central station and the network access device to calculate the traffic imposed by the dial-up subscribers as subscribers accessing the Internet through the existing PSTN or ISDN network.

The number of required lines is calculated using the Erlang-B formula, similar to the relay link capacity calculation method of the telephone network, to calculate the number of lines satisfying the quality target level (or call blocking probability) of 1% (or 0.5% in some cases).

In addition, the charge traffic is calculated by Equation 3 using the number of dial-up subscribers in the predicted design year.                     

<Equation 3>

Traffic charged per subscriber = (64 Kbps × required lines × average utilization) / subscribers

Here, 64 Kbps means the telephone line speed and the average utilization rate is a ratio that can be calculated by experience as an average ratio of 64 Kbps subscribers use.

The present invention as described above is a method of calculating the traffic charged per subscriber by dividing the group by access service, and provides the subscriber with high speed and high quality service, and at the same time, the network operator can construct the network economically and efficiently. have.

In addition, it is possible to prevent over-investment during network design and construction by calculating the busy hour from the entire network position and applying it to all services, rather than applying the busy hour for each service.
