Abstract

Described is a technology by which a network device uses a document to provide its device description information to a network entity upon connection to a network. From the device description information, the device is provisioned, via a provisioning document by which the device configures itself for interaction with the network. In one example, the documents are XML-based documents each referenced via a uniform resource locator. In one implementation, a discovery agent detects a device broadcasting a discovery message on a network. The discovery agent determines whether the device has been previously provisioned on the network, (and is not being re-provisioned). If so, an assigned network server is directed to take over interaction with the device. If not, the discovery agent provides data to a provisioning agent that provisions the device by providing a device provisioning document by which the device configures itself for interaction with the network.

Claims

1. In a computer networking environment, a method comprising:

detecting a device that is coupled to a network;

obtaining a description document corresponding to the device, the description document including information that describes the device; and

providing a provisioning document based on the information included in the description document, including based on at least some of any device-independent information, the provisioning document containing device configuration information by which the device may configure itself for operation with at least one other network entity.

2. The method of claim 1 wherein obtaining the description document comprises retrieving the description document based on a uniform resource locator provided by the device.

3. The method of claim 1 wherein providing the provisioning document comprises assembling the provisioning document and transferring the provisioning document based on a uniform resource locator provided by the device.

4. The method of claim 1 wherein providing the provisioning document comprises transferring a provisioning document to the device.

5. The method of claim 1 further comprising, retrieving the provisioning document previously transferred to the device.

6. The method of claim 1 wherein detecting a device that is coupled to a network comprises receiving a broadcast message from the device.

7. The method of claim 1 wherein providing the provisioning document comprises accessing a configuration data store based on at least some of the information included in the description document to assemble at least some of the provisioning document.

8. The method of claim 1 further comprising, detecting an acknowledgement that the device received the provisioning document, maintaining information that the device is known and provisioned with respect to the network, and further interacting with the device via a network entity.

9. The method of claim 1 further comprising, registering the device for management by a particular server on the network.

10. In a computer networking environment having a network device coupled thereto, a system comprising:

a discovery agent that detects when the device is initially coupled or re-coupled to the network;

a provisioning agent coupled to the discovery agent that uses a device description document, including use of at least some of any device-independent information in the device description document, to provide a provisioning description document to the device when the device is not already provisioned or is being re-provisioned, the device configurable for interaction with at least one other entity on the network by the provisioning document; and

a network entity that interacts with the device once the device is configured according to the provisioning description document.

11. The system of claim 10 wherein the network entity comprises a server and wherein the discovery agent is incorporated into the server.

12. The system of claim 10 wherein the device comprises a communication terminal and wherein the network entity comprises a server that facilitates connections between one or more communication terminals.

13. The system of claim 10 wherein the network device is coupled to the discovery agent via a wired or wireless local area network connection, or the network device is coupled to the discovery agent via a wired or wireless Internet connection.

14. The system of claim 10 wherein the provisioning agent is coupled to the discovery agent coupled by a pool into which data corresponding to the device is logged by the discovery agent for consumption by the provisioning agent.

15. The system of claim 10 wherein the device description document and provisioning description document are each structured documents that each include a URI reference.

16. The system of claim 10 wherein the device description document includes data corresponding to physical device configuration, device maintenance or device management, or any combination of physical device configuration, device maintenance or device management.

17. The system of claim 10 further comprising a data store containing information corresponding to already provisioned devices, and wherein the discovery agent accesses the data store to determine whether the device is initially coupled to the network or is an already-provisioned device that is re-coupled to the network.

18. The system of claim 10 wherein the device includes a configuration mechanism that configures at least some device settings based on the provisioning description document, and a recovery mechanism that broadcasts a discovery message following a state change to the device with respect to the network.

19. A computer-readable medium having computer-executable instructions, which when executed perform steps, comprising, detecting a device coupled to a network, determining whether the device needs to be provisioned or needs to be re-provisioned on the network, and if so, communicating with a network server that is configured to interact with the device, and if not, providing data to a provisioning agent to provision the device for interaction with the network, the data corresponding to a device description document, including at least some of any device-independent information in the device description document.

20. The computer-readable medium of claim 19 wherein determining whether the device needs to be provisioned or needs to be re-provisioned on the network comprises accessing a data store, and when the data store indicates the device needs to be provisioned or needs to be re-provisioned, wherein providing the data to the provisioning agent comprises provided the device description document to the provisioning agent, or providing a reference to the device description document to the provisioning agent.
