Abstract
A method to control a network device in a network comprising several devices includes a first controller that operates to prevent another controller from performing an unwanted overtaking of a network device that is currently controlled by the first controller. In one embodiment, the first controller has the ability to reserve a controllable network device to thereby become its primary controller, so that the first controller may maintain control over the controllable network device against control demands of other controllers present in the network.
Claims18
A method to control a controllable device with a control device in a network comprising several control devices, comprising:
- reserving the controllable device with a first control device as a primary controller;
- and
- preventing a second control device or a further control device from overruling primary control of the first control device with secondary control commands, the second control device being able to reserve the controllable device after the reservation of the first control device as a secondary controller so that the further control device can not overrule secondary control of the second control device with further control commands, the controllable device sending a rejection to the second control device working as the secondary controller trying to overrule the first control device working as the primary controller or to the further control device trying to overrule the first control device working as the primary controller, or the second control device, working as the secondary controller, and said rejection including a list of all primary or secondary controllers, or both the primary and secondary controllers.
A method to control a controllable device with a control device in a network comprising several control devices, comprising:
- reserving the controllable device with a first control device as a primary controller;
- and
- preventing a second control device or a further control device from overruling primary control of the first control device with secondary control commands, the first control device being able to reserve the controllable device or pre-empt another control device, via a resource manager included in the network.
A system for managing device control in an electronic network, comprising:
- an electronic device, coupled to said electronic network, to perform specified functions;
- a first controller, coupled to said electronic network, to establish a primary control over said electronic device;
- a second controller, coupled to said electronic network, to seek said primary control over said electronic device;
- and
- a resource manager configured to arbitrate between said first controller and said second controller for controlling access to said primary control over said electronic device.
A system for managing resources in an electronic network, comprising:
- a network resource, coupled to said electronic network, to perform specified functions;
- a first client, coupled to said electronic network, to request a primary control over said network resource;
- a resource manager configured to reserve said primary control over said network resource for said first client;
- and
- a second client coupled to said electronic network to seek said primary control over said network resource, said resource manager negotiating between said first client and said second client to obtain said primary control over said network resource.

- a first client, coupled to said electronic network, to request a primary control over said network resource;
- a resource manager configured to reserve said primary control over said network resource for said first client;
- and a second client coupled to said electronic network seek said primary control over said network resource, said resource manager negotiating between said first client and said second client to obtain said primary control over said network resource, said network resource being shared by a primary access for full control of said network resource and a secondary access for limited control of said network resource.
