Abstract

A method of performing a network management transaction between a network device, having a network management agent installed thereon, and a remote device, having a web-browser installed thereon, is described. The method involves firstly performing a network management function relating to the network device. Data concerning the network management function is then propagated from the agent to the remote device in a format capable of display by the browser. More specifically, a document is propagated from the agent to the remote device for display by the browser, the document incorporating the data concerning the network management function. The document may be an HTML document. Alternatively, the data may be propagated in a format for display by the browser under the direction of an application program resident of the remote device.

Claims

1. A method of performing a network management function, the method including:

communicating a markup language document to a client application, the markup language document including a plurality of Uniform Resource Identifiers, each including a method token specifying a network management function; and

receiving from the client application, responsive to a user-selection of at least one Uniform Resource Identifier, a request to perform the network management function specified by the method token with respect to each managed object identified by a selected Uniform Resource Identifier.

2. The method of claim 1 wherein the method token specifies a retrieval network management function with respect to a managed object.

3. The method of claim 2 wherein the retrieval network management function comprises retrieving at least a first value from the managed object.

4. The method of claim 3 wherein the request includes a request line specifying the retrieval network management function and a body identifying the managed object and a parameter from which to retrieve the at least first value.

5. The method of claim 1 wherein the method token specifies an allocation network management function with respect to a managed object.

6. The method of claim 5 wherein the allocation network management function allocates at least a first value to the managed object.

7. The method of claim 6 wherein the request includes a request line specifying the allocation network management function and a body identifying the managed object and the at least first value.

8. The method of claim 1 wherein the method token specifies a trap set management function with respect to a managed object.

9. The method of claim 1 wherein a parser initializes a URI block with values contained in the request to perform the network management function.

10. The method of claim 1 wherein the method token specifies multiple network management functions to be performed with respect to multiple managed objects.

11. The method of claim 1 wherein the request is to perform the network management function with respect to a Managed Information Base object.

12. The method of claim 1 wherein the markup language document comprises a HyperText Markup Language document.

13. The method of claim 1 wherein the client is a browser application.

14. The method of claim 1 including establishing a connection, via a communications network between a network management agent and the client application, and maintaining the connection for multiple network management transaction between the network management agent and the client application.

15. A system comprising:

a response entity to communicate a markup language document to a client application via a communications network, the markup language document including a plurality of Uniform Resource Identifiers, each including a method token specifying a network management function; and

a request entity to receive from the client application via the communications network and responsive to a user-selection of at least one Uniform Resource Identifier, a request to perform the network management function specified by the method token with respect to each managed object identified by a selected Uniform Resource Identifier.

16. The system of claim 15 wherein the method token specifies the network management function to be performed to respect to a managed object.

17. The system of claim 16 wherein the managed object is a Managed Information Base (MIB) object.

18. A system comprising:

first means for communicating, via communications means, a markup language document from a network management means to a client, the markup language document including a plurality of Uniform Resource Identifiers, each including a method token specifying a network management function; and

second means for receiving, from the client via the communications means and responsive to a user-selection of at least one Uniform Resource Identifier, a request to perform the network management function specified by the method token with respect to each managed object identified by a selected Uniform Resource Identifier.

19. A machine-readable medium having stored a sequence of instructions that, when executed by the machine, cause the machine to:

communicate via a communications network a markup language document to a client application, the markup language document including a plurality of Uniform Resource Identifiers, each including a method token specifying a network management function; and

receive, from the client application via the communications network and responsive to a user-selection of at least one Uniform Resource Identifier, a request to perform the network management function specified by the method token with respect to each managed object identified by a selected Uniform Resource Identifier.

20. A method comprising:

communicating a markup language document to a client application, the markup language document including at least one Uniform Resource Identifier including a method token specifying a protocol; and

receiving from the client application, responsive to a user-selection of the at least one Uniform Resource Identifier, a request to perform a network management function using the protocol specified by the method token with respect
