Abstract

Herein described is a system and method of detecting the presence of a docking station that provides data storage functionality. The docking station broadcasts a beacon signal to a computing device that is identified by way of a predefined IP multicast address. The beacon signal may be forwarded to the computing device by way of a switching device. The switching device, uses an address resolution logic, and is capable of forwarding one or more data packets which have their destination address set to the predefined IP multicast address. The computing device configured with the predefined IP multicast address recognizes the docking station that broadcasts the beacon signal, as a docking station that provides data storage and data retrieval functionality. The system may be implemented using a server application software resident in the docking station and a client application software resident in each of the one or more computing devices.

Claims

1. A method of detecting the presence of a docking station providing data storage functionality comprising:

broadcasting a beacon signal from said docking station, said beacon signal comprising a destination address, said destination address set equal to a predefined multicast address;

receiving said beacon signal by one or more data computing devices; and

responding to said docking station by said one or more data computing devices if said one or more data computing devices implements a multicast socket using said predefined multicast address, said docking station comprising a data storage device, said data storage device providing a storage depository for one or more data files provided by said one or more data computing devices.

2. The method of claim 1 further comprising using a switching device to forward said beacon signal to said one or more data computing devices.

3. The method of claim 2 wherein said switching device provides address resolution logic capable of forwarding one or more packets received at a primary port to one or more secondary ports based on said predefined multicast address.

4. The method of claim 1 wherein said data docking station is networked into a local area network, said docking station providing data storage functionality for one or more data computing devices that are networked in said local area network.

5. The method of claim 4 wherein said docking station and said one or more data computing devices reside within the same subnet of said local area network.

6. The method of claim 1 wherein said one or more data computing devices comprises a portable computing device.

7. The method of claim 6 wherein said portable computing device comprises a notebook or laptop computer.

8. The method of claim 1 wherein said beacon signal comprises a TCP or UDP message.

9. The method of claim 1 wherein said predefined multicast address is selected from any one of one or more unreserved IP multicast addresses.

10. A method for detecting the presence of a docking station providing data storage functionality, and initiating one or more data storage and/or data retrieval operations using said docking station, said method comprising:

first executing a server application software when said docking station is powered up;

broadcasting one or more messages having a destination address configured with a predefined multicast address, said one or more messages generated by said execution of said first software;

second executing a client application software when said portable computing device is powered up and connected to said docking station;

receiving said beacon signal by said portable computing device;

responding to said one or more messages; and

performing said one or more data storage and/or data retrieval operations, said responding and said performing facilitated by said execution of said client application software.

11. The method of claim 10 further comprising using a switching device to forward said one or more messages from a primary port of said switching device to one or more secondary ports of said switching device, said switching device using an address resolution logic.

12. The method of claim 10 wherein said predefined multicast address is selected from any one of one or more unreserved multicast addresses.

13. The method of claim 10 wherein said portable computing device comprises a notebook or laptop computer.

14. The method of claim 10 wherein said docking station comprises a data storage device used for providing said data storage functionality, said data storage device capable of expansion using one or more data storage drives, said data storage device implementing one or more data pools using said one or more data storage drives.

15. The method of claim 10 wherein said second executing is performed after an actuator is used to authenticate said portable computing device.

16. A system for detecting the presence of a docking station providing data storage functionality, said system comprising:

a server application software resident in said docking station;

a client application software resident in a data computing device;

a first processor in said docking station, said first processor executing said server application software to generate one or more signals, said one or more signals identifying said docking station as capable of said providing said data storage functionality;

a second processor in said data computing device, said second processor executing said client application software;

a switching device for forwarding said one or more signals from said docking station to said data computing device, each of said one or more signals comprising a destination address set equal to a predefined multicast address, said multicast address corresponding to a multicast socket implemented by said data computing device, said second processor executing said client application software to facilitate receiving said one or more signals by said data computing device.

17. The system of claim 16 wherein said predefined multicast address is selected from any one of one or more unreserved multicast addresses.

18. The system of claim 16 wherein said data computing device comprises a notebook or laptop computer.

19. The system of claim 16 wherein said docking station comprises a data storage device.

20. The system of claim 19 wherein said one or more signals comprises a MAC address, name, and IP address of said data storage device.

21. The system of claim 16, wherein said switching device comprises an Ethernet switch.
