Dynamic self-configuration for ad hoc peer networking using mark-up language formated description messages
View Patent ↗A device control model provides an integrated set of addressing, naming, discovery and description processes that enables automatic, dynamic and ad-hoc self-setup by devices to interoperate with other devices on a network. This permits a computing device when introduced into a network to automatically configure so as to connect and interact with other computing devices available on the network, without a user installation experience and without downloading driver software or persisting a configuration setup for connecting and interacting with such other computing devices. Upon completing interaction with such other devices, the computing device automatically releases the setup for such other devices so as to avoid persistent device configurations that might create a configuration maintenance and management burden.
1. A dynamically self-bootstrapping computing device comprising:
addressing means at the computing device for self-assigning an address for the computing device on an ad hoc network by selecting an address from a reserved range of addresses, pinging the selected address on the ad hoc network, and absent response to said pinging assigning the selected address to the computing device;
announcing means at the computing device for multi-casting an announcement message on a multi-cast communications channel of the ad hoc network informing of the computing device's assigned address;
discovery means at the computing device for listening on the multi-cast communications channel of the ad hoc network for a discovery message sent from a discovery client inquiring for a device type of the computing device;
discovery response means at the computing device for sending a response message responsive to the discovery message identifying the computing device; and
description means at the computing device responsive to a description request received by the computing device on the ad hoc network for sending a peer-accessible description message dynamically defining interaction via data messaging with the computing device to remotely operate the computing device over the ad hoc network.
2. The dynamically self-bootstrapping computing device of claim 1 wherein the description message further contains presentation data defining a user interface for remote presenting on another computing device for remotely operating the computing device over the ad hoc network.
3. The dynamically self-bootstrapping computing device of claim 2 wherein the description message further contains a link to style sheet data for defining separate views of the presentation data on said other computing device.
4. The dynamically self-bootstrapping computing device of claim 1 wherein the description message is formatted according to a mark-up language.
5. The dynamically self-bootstrapping computing device of claim 1 wherein the response message comprises a link to the description message.
6. The dynamically self-bootstrapping computing device of claim 1 wherein the response message comprises a device type identifier of the computing device.
7. The dynamically self-bootstrapping computing device of claim 1 wherein the computing device has a predetermined name, and the announcement message contains the predetermined name.
8. The dynamically self-bootstrapping computing device of claim 1 , wherein the description message defining interaction identifies a protocol to interact with the computing device and defines a data packet to exchange control information.
9. A method of dynamically configuring a computing device, comprising:
self-assigning an address for the computing device on an ad hoc network by selecting an address from a reserved range of addresses, pinging the selected address on the ad hoc network, and absent response to said pinging assigning the selected address to the computing device;
announcing on a multi-cast communications channel of the ad hoc network the computing device's assigned address;
listening at the computing device on the multi-cast communications channel of the ad hoc network for a discovery message inquiring for a device type of the computing device;
sending a response message responsive from the computing device to the discovery message identifying the device type of the computing device;
receiving a description request message at the computing device responsive to the response message; and
responding from the computing device to the description request message by sending a peer-accessible description message dynamically defining interaction with the computing device to control operational functions of the computing device over the ad hoc network.
10. The method of claim 9 , further comprising terminating the interaction with the computing device to control operational function of the computing device.
11. The method of claim 9 wherein the description message further contains presentation data defining a user interface for remote presenting on another computing device for remotely operating the computing device over the ad hoc network.
12. The method of claim 11 wherein the description message further comprises a link to style sheet data for defining separate views of the presentation data on said other computing device.
13. The method of claim 9 wherein the description message is formatted according to a mark-up language.
14. The method of claim 9 wherein the response message comprises a link to the description message.
15. The method of claim 9 wherein the computing device has a predetermined name, and the announcement message contains the predetermined name.
16. The method of claim 9 , wherein sending a response message responsive to the discovery message further comprises identifying the address assigned to the computing device.
17. The method of claim 16 , further comprising specifying a device-specific protocol of data messages for interacting with the computing device.
18. The method of claim 9 , wherein the description message defining interaction identifies a protocol to interact with the computing device and defines a data packet to exchange control information.
