Abstract

A method and apparatus for internet based network topology discovery. Extensible Markup Language (XML) based data is used to share the discovery information of devices on a network over Internet transport. XML based search engines are used to search for the discovery information. Discovery information, such as identification, location, or capability data, for example, is stored on the devices of a network in the form of XML documents. Network topology maps may be created based on the information discovered.

Claims

1. A method comprising:

formulating an Extensible Markup Language (XML) discovery information query at a console, the console includes a managing device to manage network devices, wherein the XML discovery information query is initiated in one or more of the following ways automatically, and by a client;

sending the XML discovery information query to a plurality of Internet content search engines to facilitate searching of discovery information relevant to the network devices, wherein at least one of the network devices includes an XML discovery information file, wherein at least one of the network devices does not include an XML discovery information file;

in response to sending the XML discovery information query, receiving the following through the plurality of Internet content search engines;

discovery information from the network devices that include an XML discovery information file, and

discovery information from a proxy device for the network devices that do not include XML discovery information files; and

using the retrieved discovery information to generate a network topology map for the network devices.

2. The method of claim 1, further comprising manipulating the retrieved discovery information.

3. The method of claim 2, further comprising displaying the manipulated discovery information.

4. A tangible machine-readable storage medium having stored thereon data representing sets of instructions which, when executed by a machine, cause the machine to:

formulate an Extensible Markup Language (XML) discovery information query at a console, the console includes a managing device to manage network devices, wherein the XML discovery information query is initiated in one or more of the following ways automatically, and by a client;

send the XML discovery information query to a plurality of Internet content search engines to facilitate searching of discovery information relevant to the network devices, wherein at least one of the network devices includes an XML discovery information file, wherein at least one of the network devices does not include an XML discovery information file;

in response to the sending of the XML discovery information query, receive the following through the plurality of Internet content search engines;

discovery information from the network devices that include an XML discovery information file, and

discovery information from a proxy device for the network devices that do not include XML discovery information files; and

use the retrieved discovery information to generate a network topology map for the network devices.

5. The tangible machine-readable storage medium of claim 4, wherein the sets of instructions which, when executed by the machine, further causes the machine to manipulate the retrieved discovery information.

6. The tangible machine-readable storage medium of claim 5, wherein the sets of instructions which, when executed by the machine, further cause the machine to display the manipulated discovery information.
