Abstract

A method for remote management of a network hardware device using an industry standard internetwork protocol. A client and protocol stack are implemented on the computer network and an embedded server is installed on the network hardware device. Using the Hypertext Transfer Protocol (HTTP) and an available HTTP client, remote management of a hardware device is facilitated.

Claims

1. A method for generating an HTML file response to remotely manage a network hardware device having an embedded HTTP server across a network with an HTTP client device, comprising the steps of:

transmitting an HTTP request from an HTTP client to an HTTP server embedded within a network hardware device;

said embedded server controlling the network hardware device and obtaining current hardware status of the network hardware device in response to the request and formulating the current hardware status in HTML file format;

said embedded server returning said HTML file to said client; and

said client receiving and rendering said HTML file according to HTTP.

2. The method of claim 1, further comprising a step of:

said client device displaying the current hardware status in graphical form.

3. A method of remotely managing a network hardware device having an embedded HTTP server with an HTTP client device across a network, comprising the steps of:

the client device establishing a connection with the embedded server via the network;

the client device sending a management request in URL format to the embedded server via the network;

the embedded server receiving and rendering the management request; and

the embedded server controlling and modifying operational behavior of the network hardware device according to the management request.

4. The method of claim 3, wherein said step of establishing a connection is according to the TCP/IP protocol.

5. The method of claim 3, wherein the network hardware device has a particular configuration before receiving the management request, and wherein said step of modifying comprises a step of changing the configuration of the network hardware device.

6. The method of claim 3, wherein said step of modifying comprises a step of controlling the network hardware device.

7. The method of claim 6, wherein the network hardware device includes a plurality of ports, and wherein said step of controlling hardware of the network hardware device comprises a step of enabling or disabling at least one of the plurality of ports of the network hardware device.

8. The method of claim 3, further comprising the steps of:

the client device sending an HTTP status request to the embedded server via the network for status information about the network hardware device;

the embedded server receiving the status request and retrieving and formulating status information of the network hardware device into an HTML file; and

the embedded server sending the HTML file according to HTTP to the client device via the network.

9. The method of claim 8, wherein said status information includes usage statistics.

10. The method of claim 8, wherein the network is the internet, and wherein the HTML file is a home page on the world wide web.

11. The method of claim 8, further comprising the step of:

the client device receiving and rendering the HTML file and displaying the status information in graphical form.

12. The method of claim 11, wherein said step of sending a management request comprises the steps of:

modifying a field of the status information; and

the client device sending a management request to the embedded server via the network to change the status of the network hardware device.

13. A network management system for enabling a client computer system to remotely manage a network hardware device having an embedded server across an internetwork, comprising:

an internetwork for enabling communication among remotely coupled computers and network devices;

an HTTP client computer system coupled to said internetwork, comprising;

a network interface for coupling to said internetwork;

a display device;

a client processor coupled to said network interface and said display device; and

a client memory coupled to said client processor that stores HTTP code executable by said processor, the HTTP code instructing said client processor to send an HTTP operational status and control request in URL format via said internetwork, to receive and render an HTTP status response from said internetwork and to display status information from said status response on said display device; and

a network hardware device coupled to said internetwork, comprising;

at least one port coupled to said internetwork;

a memory that stores executable code including an embedded HTTP server; and

a processor coupled to said at least one port and said memory that executes said embedded server in said memory, said embedded server instructing said processor when executed to receive and render said HTTP operational status and control request from said client computer system, to control the network hardware device according to said HTTP operational status and control request, to format hardware status information of said network hardware device into an HTML file, and to send said HTML file as an HTTP status response to said client computer system via said internetwork.

14. The network management system of claim 13, wherein said client computer system further comprises:

said status information including control information;

an input device to enable modification of a field of said status and control information displayed on said display device;

said client memory including code to formulate an HTTP control request to reflect said modification of said status and control information, and to send said HTTP control request to said network hardware device via said internetwork; and

said embedded server including code to instruct said processor to receive said HTTP control request and to change the operation of said network hardware device according to said HTTP control request.

15. The network management system of claim 14 wherein said network hardware device has a particular configuration before receiving said HTTP control request, and wherein said HTTP control request instructs said processor to change the configuration of said network hardware device.

16. The network management system of claim 14, wherein said HTTP control request instructs said processor to change an operational characteristic of said network hardware device.

17. The network management system of claim 14, wherein said HTTP control request instructs said processor to control hardware of said network hardware device.

18. The network management system of claim 17, wherein said network hardware device includes a plurality of ports, and wherein said HTTP control request instructs said processor to enable or disable at least one of said plurality of ports.

19. The network management system of claim 13, wherein said network hardware device comprises a repeater.

20. The network management system of claim 13, wherein said network hardware comprises a switch.
