Abstract

In accordance with a method and apparatus for synchronizing information browsing among multiple systems, a bridgeport system receives identifiers for data requests received in a first hardware system and automatically transmits the identifier of the requested data to one or more additional hardware systems. Each of these one or more additional hardware systems then retrieves the identified data, thereby keeping the data being provided in these hardware systems in synchronization.

Claims

1. In a bride server, a method of synchronizing a plurality of hardware systems coupled to the bridge server in a network environment, the method comprising:

(a) receiving by said bridge server, an identifier of data requested of an information server, from a first hardware system of the plurality of hardware systems, via a first coupling independent of said information server; and

(b) transmitting by said bridge server, the identifier to a second hardware system of the plurality of hardware systems via a second coupling in order to enable the second hardware system to synchronously retrieve the requested data from the information server.

2. The method of claim 1, wherein the first coupling includes a firewall protecting said first hardware system.

3. The method of claim 1, wherein the second coupling includes a firewall protecting said second hardware system.

4. The method of claim 1, wherein said receiving comprises receiving by said bridge server, a world wide web page Uniform Resource Locator (URL), from the first hardware system, via said first coupling independent of said information server, the URL identifying the requested data as being located on said information server.

5. The method of claim 1, wherein the network environment includes the Internet.

6. The method of claim 1, further comprising

the bridge server facilitating establishing a voice telephone connection between the first hardware system and the second hardware system while the first hardware system and the second hardware system are still enabled to synchronously receive requested data from said information server.

7. The method of claim 1, further comprising the bridge server maintaining a registration database which identifies each hardware system in a synchronized data request connection.

8. The method of claim 1, further comprising the bride server transmitting the independently received identifier to one or more additional hardware systems of the plurality of hardware systems in order to enable each of the one or more additional hardware systems to synchronously retrieve the requested data from the information server.

9. A bridging apparatus comprising:

an interface to provide communication with a network; and

control logic, coupled to the interface, operative to receive an identifier of data requested of an information server, from a first hardware system of a plurality of hardware systems via a first coupling independent of the information server, the control logic also operative to transmit the identifier to a second hardware system of the plurality of hardware systems via a second coupling to enable the second hardware system to synchronously retrieve the requested data from the information server.

10. The apparatus of claim 9, wherein the first coupling includes a firewall protecting the first hardware system.

11. The apparatus of claim 9, wherein the second coupling includes a firewall protecting the second hardware system.

12. The apparatus of claim 9, wherein the network includes the Internet.

13. The apparatus of claim 9, further comprising a driver to facilitate establishing and maintaining a voice telephone connection between the first hardware system and the second hardware system while the first hardware system and the second hardware system are still enabled to synchronously receive requested data from the information server.

14. The apparatus of claim 9, wherein the control logic is further operative to transmit the identifier to one or more additional hardware systems of the plurality of hardware systems in order to enable each of the one or more additional hardware systems to synchronously retrieve the requested data from the information server.

15. A computer-readable medium having stored thereon a plurality of instructions for synchronizing a plurality of hardware systems in a network environment, the plurality of instructions designed to be executed by a processor of a bridge server and to implement a function on the bridge seerver to:

receive an identifier of data requested of an information server, from a first hardware system of the plurality of hardware systems via a first coupling independent of the information server; and

transmit the identifier to a second hardware system of the plurality of hardware systems via a second coupling in order to enable the second hardware system to synchronously retrieve the requested data from the information server.

16. The computer-readable medium of claim 15, wherein the first coupling includes a firewall protecting the first hardware system.

17. The computer-readable medium of claim 15, wherein the second coupling includes a firewall protecting the second hardware system.

18. The computer-readable medium of claim 15, wherein the plurality of instructions are further designed to implement a function on the bridge server to facilitate establishing a voice telephone connection between the first hardware system and the second hardware system while the first hardware system and the second hardware system are still enabled to synchronously receive requested data from the information server.

19. The computer-readable medium of claim 15, wherein the plurality of instructions are further designed to implement a function to maintain on the bridge server, a registration database which identifies each hardware system in a synchronized data request connection.

20. The computer-readable medium of claim 15, wherein the plurality of instructions are further designed to implement a function on the bridge server to transmit the received identifier (independent of the information server) to one or more additional hardware systems of the plurality of hardware systems in order to enable each of the one or more additional hardware systems to synchronously retrieve the requested data from the information server.
