Abstract

The present invention provides a method for a local area network router, that allows communication between a number of remotely located users, and a plurality of peripheral devices connected to the local area network router. Users may access the local area network using wireless devices or the Internet. The peripheral devices, which may include a wide variety of multi-media storage, playback, printing, or other functions, are connected to the router via local interfaces, which communicate with the peripheral devices via established protocols. Each of the peripheral devices is provided with an IP address, which facilitates direct communication of the users with the peripheral devices and permits direct communication with the devices over the Internet. Data packets destined for the IP address of a peripheral device are router through the local interface, which converts the data utilizing compatible communication protocols for the target peripheral device.

First claim

What is claimed is:

1. A local area network router that allows communications between a number of remotely located users and a plurality of peripheral devices connected to the local area network router comprising:
a central processing apparatus comprising memory;
a plurality of peripheral devices coupled to said central processing apparatus,
each of said plurality of peripheral devices provided with an IP address, wherein said memory stores said IP address for each of said plurality of peripheral devices to enable direct communication of users with said plurality of peripheral devices; and
an Internet interface coupled to said central processing apparatus to provide Internet connectivity to each of said plurality of peripheral devices whose IP address is stored in said memory, routing at least one data packet to at least one of said plurality of peripheral devices assigned said IP address;
wherein users directly access the local area network router using wireless devices or the Internet; and
wherein said central processing apparatus routes any data packet directed to an IP address not stored in said memory to the Internet.

2. A local area network router as recited in claim 1 :
wherein said plurality of peripheral devices are coupled to at least one of a plurality of local interfaces, said at least one of a plurality of local interfaces being coupled to said central processing apparatus; and
wherein said plurality of peripheral devices communicate with said at least one of a plurality of local interfaces using peripheral interface protocols.

3. A local area network router as recited in claim 2 :
wherein at least one of said plurality of local interfaces is wireless.

4. A local area network router as recited in claim 2 :
wherein said at least one of a plurality of local interfaces comprises:
(a) a universal serial bus (USB) port
(b) a RS 232 serial port
(c) an IEEE 1394 Fire Wire port
(d) a line printer terminal (LPT) port
(e) a small computer system interface (SCSI) port
(f) an Ethernet port
(g) a digital subscriber line (DSL) port
(h) a video cable port
(i) a V.90 telephone line modem port
(j) an optical fiber port.

5. A local area network router as recited in claim 1 :
wherein said at least one of a plurality of peripheral devices comprises:
(a) a camera
(b) a printer
(c) a scanner
(d) a copier
(e) a hard drive
(f) a CD-R/W drive
(g) a DVD drive/player
(h) a removable media storage device
(i) a streaming tape drive
(j) an Ethernet hub or router
(k) a telephone
(l) a modem
(m) a game controller
(n) a USB hub
(o) an MPEG player.

6. A local area network router as recited in claim 2 :
wherein at least one of said plurality of local interfaces can be changed without re-booting said central processing apparatus.

7. A local area network router as recited in claim 1 :
wherein said IP addresses of said plurality of peripheral devices are updated to remove at least one old peripheral device or add at least one new peripheral device and saved in said memory.

8. A local area network router as recited in claim 1 :
wherein a data packet with a destination IP address stored in said memory, originating from said Internet interface, is delivered to said IP address.

9. A local area network router as recited in claim 2 :
wherein a data packet with a destination IP address stored in said memory, originating from said at least one of a plurality of local interfaces, is delivered to said IP address.

10. A method for providing a local area network router comprising:
detecting a data packet en route from an originating IP address to a destination IP address;
sending said data packet to a wide area network if the destination IP address is not on a list of local IP addresses;
sending said data packet to a local interface coupled to a peripheral device having said destination IP address if said destination IP address is on said list of local IP addresses; and
translating said data packet into an appropriate protocol for said peripheral device coupled to said local interface.

11. A method for providing a local area network router as recited in claim 10 :
wherein said local interface comprises:
(a) a universal serial bus (USB) port
(b) a RS 232 serial port
(c) an IEEE 1394 Fire Wire port
(d) a line printer terminal (LPT) port
(e) a small computer system interface (SCSI) port
(f) an Ethernet port
(g) a digital subscriber line (DSL) port
(h) a video cable port
(i) a V.90 telephone line modem port
(j) an optical fiber port.

12. A method for providing a local area network router as recited in claim 10 :
wherein said peripheral device comprises:
(a) a camera
(b) a printer
(c) a scanner
(d) a copier
(e) a hard drive
(f) a CD-R/W drive
(g) a DVD drive/player
(h) a removable media storage drive
(i) an Ethernet hub or router
(j) a telephone
(k) a modem
(l) a game controller
(m) a USB hub
(n) an MPEG player.

13. A method for providing a local area network router as recited in claim 10 :
wherein said local interface is wireless.

14. A method for providing a local area network router as recited in claim 10 further comprising:
changing said local interface without re-booting said local area network router.

15. A method for providing a local area network router as recited in claim 10 further comprising:
changing said peripheral device without re-booting said local area network router.

16. A method for providing a local area network router as recited in claim 15 further comprising:
removing said destination IP address of said peripheral device from said list of local IP addresses after uncoupling said peripheral device from said local interface.

17. A method for providing a local area network router as recited in claim 15 further comprising:
adding a new destination IP address of a new peripheral device to said list of local IP addresses after coupling said new peripheral device to said local interface.
