Abstract

An ATM I/F for transmitting data to a data transmission destination via a communication network, a data transmission server, and a data transmission managing device for calculating a network necessary for data transmission on the basis of the data quantity of the data to be transmitted and the transmission completion time indicating the time of completion of data transmission to the data transmission destination are provided. Accounting information is generated on the basis of the calculated network band and transmission time. The data is transmitted to the data transmission destination by using the calculated network band. The data transmission to the data transmission destination is completed by the transmission completion time, and accounting information is generated. Thus, when transmitting data via the communication network, the data transmission completion time is designated in advance for data transmission.

Claims

1. A data transmitting device, comprising:

a data transmitting part for transmitting data to a data transmission destination via an external communication channel;

a data storage part for storing the data transmitted by the data transmitting part;

an arithmetic part for calculating a network band necessary when the data transmitting part transmits the data, based on a data quantity of the data stored in the data storage part and transmitted by the data transmitting part and a transmission completion time indicating a time of completion of data transmission to the data transmission destination;

an accounting part for generating accounting information based on the basis of the network band calculated by the arithmetic part and a transmission time at the data transmitting part; and

a transmission control part for controlling the data transmitting part to transmit the data stored in the data storage part to the data transmission destination by using the network band calculated by the arithmetic part and to complete the data transmission to the data transmission destination by the transmission completion time, and for controlling the accounting part to generate the accounting information.

2. A data transmitting device as claimed in

claim 1

, wherein the transmission control part reserves processing contents of both the data transmitting part and the data storage part based on a reservation status of both the data transmitting part and the data storage part, and transmits the data to the data transmission destination by the transmission completion time.

3. A data transmitting device as claimed in

claim 2

, wherein the transmission control part changes the reservation contents at both the data transmitting part and the data storage part on the basis of the reservation status of the data transmission destination.

4. A data transmitting device as claimed in

claim 1

, wherein the transmission control part generates format information of the data to be transmitted from the data transmitting part to the data transmission destination and transmits the format information to the data transmission destination, and wherein the accounting part generates accounting information based on the contents of format conversion at the data transmission destination.

5. A data transmitting device as claimed in

claim 1

, wherein the arithmetic part calculates the network band based on contents of format conversion at the data transmission destination.

6. A data transmitting method, comprising the steps of:

calculating a network band necessary for transmitting data based on a data quantity of data transmitted to a data transmission destination, a transmission completion time indicating a time of completion of data transmission to the data transmission destination;

transmitting stored data to the data transmission destination by using the calculated network band; and

generating accounting information based on both the network band and the transmission time.

7. A data transmitting method as claimed in

claim 6

, wherein a data transmitting section and a data storage section are reserved based on a reservation status of both the data transmitting section and the data storage section, and the data is transmitted to the data transmission destination by the transmission completion time.

8. A data transmitting method as claimed in

claim 7

, wherein reservation contents at both the data transmitting section and the data storage section are changed based on the reservation status of the data transmission destination.

9. A data transmitting method as claimed in

claim 6

, wherein format information of the data to be transmitted to the data transmission destination is generated and transmitted to the data transmission destination, and wherein accounting information is generated based on contents of format conversion at the data transmission destination.

10. A data transmitting method as claimed in

claim 6

, wherein the network band is calculated based on contents of format conversion carried out at the data transmission destination.

11. A data transmission managing device, comprising:
