Abstract

The present invention relates to a router apparatus and a bandwidth controlling method thereof. An object of the present invention is to provide a router apparatus which allows a network connection bandwidth to be equally used by a plurality of clients without need to perform a special bandwidth acquisition procedure. A router apparatus according to the present invention is a router apparatus for controlling a bandwidth, said router apparatus being disposed between a network and a plurality of clients under an environment in which the bandwidth for connection with a network is shared by a plurality of clients, said router apparatus comprising: address management means for assigning an address to a client in response to a network connection request issued from the client; and bandwidth management means for reassigning the bandwidth to the assigned address and addresses assigned to the other clients.

Claims

1. A router apparatus for controlling a bandwidth, said router apparatus being disposed between a network and a plurality of clients under an environment in which the bandwidth for connection with a network is shared by a plurality of clients, said router apparatus comprising:

address management means for assigning an address to a client in response to a network connection request issued from the client; and

bandwidth management means for reassigning the bandwidth to the assigned address and addresses assigned to the other clients.

2. The router apparatus as set forth in claim 1,

wherein the bandwidth management means adopts a bandwidth reassigning method which equally assigns the bandwidth.

3. The router apparatus as set forth in claim 1,

wherein the bandwidth management means adopts a bandwidth reassigning method which reassign the bandwidth in accordance with a prescribed priority.

4. The router apparatus as set forth in claim 1,

wherein the network is the Internet, and

wherein the address management means uses private IP addresses as addresses assigned to the clients, and

wherein the bandwidth management means has an address translation table for bi-directionally translating the private IP addresses and Internet'"'"'s global IP addresses.

5. The router apparatus as set forth in claim 1,

wherein the network is the Internet, and

wherein the bandwidth management means assigns different bandwidths to different Internet applications.

6. The router apparatus as set forth in claim 5,

wherein the bandwidth management means assigns different bandwidths to different port numbers through which communication data packets pass.

7. A bandwidth controlling method in a router apparatus for controlling a bandwidth, said router apparatus being disposed between a network and a plurality of clients under an environment in which the bandwidth for connection with a network is shared by a plurality of clients, said method comprising:

address management step for assigning an address to a client in response to a network connection request issued from the client; and

bandwidth management step for reassigning the bandwidth to the assigned address and addresses assigned to the other clients.

8. The bandwidth controlling method as set forth in claim 7,

wherein the bandwidth management step adopts a bandwidth reassigning method which equally assigns the bandwidth.

9. The bandwidth controlling method as set forth in claim 7,

wherein the bandwidth management step adopts a bandwidth reassigning method which reassign the bandwidth in accordance with a prescribed priority.

10. The bandwidth controlling method as set forth in claim 7,

wherein the network is the Internet, and

wherein the address management step uses private IP addresses as addresses assigned to the clients, and

wherein the bandwidth management step performs bandwidth control with reference to an address translation table for bi-directionally translating the private IP addresses and Internet'"'"'s global IP addresses.

11. The bandwidth controlling method as set forth in claim 7,

wherein the network is the Internet, and

wherein the bandwidth management step assigns different bandwidths to different Internet applications.

12. The bandwidth controlling method as set forth in claim 11,

wherein the bandwidth management step assigns different bandwidths to different port numbers through which communication data packets pass.

13. A record medium on which a program is recorded for causing a computer to execute a bandwidth controlling method in a router apparatus for controlling a bandwidth, said router apparatus being disposed between a network and a plurality of clients under an environment in which the bandwidth for connection with a network is shared by a plurality of clients, said method comprising:

address management step for assigning an address to a client in response to a network connection request issued from the client; and

bandwidth management step for reassigning the bandwidth to the assigned address and addresses assigned to the other clients.

14. The record medium on which a program is recorded as set forth in claim 13,

wherein the bandwidth management step adopts a bandwidth reassigning method which equally assigns the bandwidth.

15. The record medium on which a program is recorded as set forth in claim 13,

wherein the bandwidth management step adopts a bandwidth reassigning method which reassign the bandwidth in accordance with a prescribed priority.

16. The record medium on which a program is recorded as set forth in claim 13,

wherein the network is the Internet, and

wherein the address management step uses private IP addresses as addresses assigned to the clients, and

wherein the bandwidth management step performs bandwidth control with reference to an address translation table for bi-directionally translating the private IP addresses and Internet'"'"'s global IP addresses.

17. The record medium on which a program is recorded as set forth in claim 13,

wherein the network is the Internet, and

wherein the bandwidth management step assigns different bandwidths to different Internet applications.

18. The record medium on which a program is recorded as set forth in claim 17,

wherein the bandwidth management step assigns different bandwidths to different port numbers through which communication data packets pass.
