Abstract

Methods and systems for managing a network using a handheld communications device are provided. The methods and systems provide advantages for Network Administrators that require mobility in accessing information about network connected devices and for controlling selected network management functions.

Claims

1. A method of network management using a palm-sized computer, including:

receiving a request to submit a page that indicates a network management function, wherein the page includes a data field;

in response to receiving the request, modifying a uniform resource locator (URL) by replacing a name attribute of the data field with an index value that corresponds to a relative position of the data field on the page, wherein the modified URL includes (i) a page name, and (ii) user data associated with each of the index values;

transmitting the modified URL to a proxy server by using a compact transfer protocol (CTP), wherein the proxy server uses the modified URL to (i) generate a HTTP query and to (ii) send the HTTP query to a web server; and

receiving network management information from the proxy server, responsive to the transmitted URL.

2. The method of claim 1, wherein the network management function is changing a configuration of a device.

3. The method of claim 1, wherein the network management function is changing an inventory description of a device.

4. The method of claim 1, wherein the network management function is accessing historical information about a device.

5. The method of claim 1, wherein the network management function is accessing web-based support information.

6. The method of claim 1, wherein the network management function is accessing intranet-based support information.

7. The method of claim 1, wherein the network management function is accessing server-based support information.

8. The method of claim 1, wherein transmitting the generated URL to a proxy server includes connecting to a synchronization server by placing the palm-sized computer in communications cradle and pressing a hot sync button.

9. The method of claim 8, wherein pressing the hot sync button starts the synchronization server.

10. The method of claim 1, wherein transmitting the generated URL to a proxy server includes connecting to a synchronization server by using a radio signal and a wireless communication server in communication with the synchronization server.

11. The method of claim 10, wherein a wireless communication server starts a synchronization server when needed.

12. The method of claim 10, wherein connecting with the synchronization server includes using encryption.

13. The method of claim 1, wherein transmitting the generated URL to a proxy server includes connecting to a synchronization server by using an infrared signal.

14. The method of claim 1, wherein the transmitting and receiving including encoding and decoding in a compact markup language.

15. The method of claim 14, wherein the compact markup language utilizes five-bit encoding of characters.

16. The method of claim 14, wherein the compact markup language utilizes variable length strings for markup tags and characters.

17. The method of claim 10, wherein the page includes a form and data and the received network management information includes an updated version of some or all of the data.

18. The method of claim 10, wherein the page includes a form and data and the received network management information includes an updated version of some or all of the data and does not include the form.

19. A method of network inventory management using a palm-sized computer, including:

receiving a request to submit a page that indicates a network management function, wherein the page includes a data field;

in response to receiving the request, modifying a uniform resource locator (URL), by replacing a name attribute of the data field with an index value that corresponds to a relative position of the data field on the page, wherein the modified URL includes (i) the page name, and (ii) a network inventory scope choice associated with the field index values;

transmitting the modified URL to a proxy server by using a compact transfer protocol (CTP), wherein the proxy server uses the modified URL to (i) generate a HTTP query and (ii) send the HTTP query to a web server; and

receiving network inventory information, responsive to the network inventory scope choice indicated in the modified URL.

20. The method of claim 19, wherein the network inventory information includes a configuration of a device.

21. The method of claim 19, wherein the network inventory information includes an inventory description of a device.

22. The method of claim 19, wherein the network inventory includes historical information about performance of a device.

23. The method of claim 19, wherein the network inventory information includes web-based support information.

24. The method of claim 19, wherein the network inventory information includes intranet-based support information.

25. The method of claim 19, wherein the network inventory information includes server-based support information.

26. The method of claim 19, wherein transmitting a URL to a proxy server includes connecting to a synchronization server by placing the palm-sized computer in communications cradle and pressing a hot sync button.

27. The method of claim 26, wherein pressing the hot sync button starts the synchronization server.

28. The method of claim 19, wherein transmitting a URL to a proxy server includes connecting to a synchronization server by using a radio signal and a wireless communication server in communication with the synchronization server.

29. The method of claim 28, wherein a wireless communication server starts a synchronization server when needed.

30. The method of claim 28, wherein connecting with the synchronization server includes using an encryption.

31. The method of claim 30, wherein transmitting a URL to a proxy server includes connecting to a synchronization server by using an infrared signal.

32. The method of claim 30, wherein the transmitting and receiving including encoding and decoding in a compact markup language.

33. The method of claim 32, wherein the compact markup language utilizes five-bit encoding of characters.

34. The method of claim 32, wherein the compact markup language utilizes variable length strings for markup tags and characters.

35. The method of claim 28, wherein the page includes a form and data and the received network inventory information includes an updated version of some or all of the data.

36. The method of claim 28, wherein the page includes a form and data and the received network inventory information includes an updated version of some or all of the data and does not include the form.

37. A system for network management using a palm-sized computer, including:

a palm-sized computer running a browser application, wherein the browser application sends a modified Uniform Resource Locator (URL) to a proxy server using a compact transfer protocol (CTP), wherein the URL includes (i) the page name, (ii) a field index value corresponding to a name attribute of the data field, the field index value indicating a relative order for each of the data fields on the page, and (iii) network inventory scope choices associated with the field index values;
