Abstract

The present invention provides for a methods, system, and apparatus relating to data transmission. One method of the present invention includes representing data using at least one pulse based on a Gaussian wave form, sending the at least one pulse over an electrically conductive guided media, and recovering the data from the at least one pulse. The present invention can be used in conjunction with telephony applications, cable tv applications, and data bus applications.

Claims

1. A method for data transmission, comprising:

representing data using at least one pulse based on a Gaussian wave form;

sending the at least one pulse over an electrically conductive guided media;

receiving the at least one pulse over the electrically conductive guided media;

recovering the data encoded in the at least one pulse after receiving the at least one pulse over the electrically conductive guided media;

storing individual bytes of the data recovered from said Gaussian wave form signals in selectable memory locations of a plurality of buffer memories, each buffer memory for storing a plurality of said bytes; and

adding header data to outputs of said buffer memories and forming a plurality of variable length packets, each packet comprising bytes from at least one Gaussian wave form channel from a plurality of said Gaussian wave form signals;

transmitting said plurality of packets in Gaussian wave form output signals to a device for switching packets of said output signals; and

wherein said selectable memory locations are assigned to at least one byte of data into at least one channel in a common switching system device.

2. The method of claim 1 wherein the transmitting of said plurality of packets is performed synchronously.

3. The method of claim 1 wherein the transmitting of said plurality of packets is performed asynchronously.

4. The method of claim 1 wherein the storing of the individual bytes is byte organized so that a plurality of bytes forming a data packet can be transmitted in serial or parallel.

5. The method of claim 1 wherein each packet encapsulates data from a separate protocol.

6. The method of claim 5 wherein the separate protocol is selected from the set consisting of Ethernet, Asynchronous Transport Mode (LDL), Synchronous Optical Network (SONET), File Transfer Protocols (FTP), Transmission Control Protocol (TCP), Hyper-text Transport Protocol (HTTP), Internetwork Packet Exchange (IPX), Motion Picture Expert Group (MPEG), MPEG-1 Audio 3 (MP3) System Network Architecture (SNA), TCP/IP, IP, IPX/SPX, Netbui, Infiniband, Advancand Novell, Ethernet, Gigabit Ethernet, CDMA, Ultra-Wide Band, MegaBand, Advanced TCA, iSCSI, Fiber Channel, and Periperal Component Interconnect (PCI).

7. The method of claim 1 wherein the header data includes at least one of LDL Payload Data Length, CRC Check, CRC Type, LDL Priority, Broadcast, Stream ID, Stream ID Length, Checksum, and Payload Type.

8. The method of claim 1 wherein each packet is secured using encryption.

9. The method of claim 1 wherein each packet is secured using secured socket layer technology (SSL).

10. The method of claim 1 wherein each packet encapsulates XML data.

11. The method of claim 1 wherein the electrically conductive guided media comprises a telephone twisted pair.

12. The method of claim 1 wherein the electrically conductive guided media comprises a coaxial cable associated with CATV.

13. The method of claim 1 further comprising managing services associated with the data transmission.

14. A method for data transmission, comprising:

receiving data over a first network implementing a first protocol encapsulating at least one protocol data unit associated with the first protocol within a payload area of a packet;

adding header data to the packet;

representing the packet using at least one pulse based on a Gaussian wave form;

sending the at least one pulse over an electrically conductive guided media receiving the at least one pulse;

recovering the packet;

recovering the at least one protocol data unit;

forming data packets according to the first protocol;

sending the data packets over a second network using the first protocol.

15. The method of claim 14 wherein the electrically conductive guided media comprises telephone twisted pair.

16. The method of claim 14 wherein the electrically conductive guided media comprising coaxial cable.
