Abstract
A control system is provided for a network system having a plurality of redundant elements wherein each redundant element has an active state and a standby state. The control system comprises a peer-to-peer-like control system that is operative to select the active and standby states of the redundant elements and a central controller system that is operative to send messages to the peer-to-peer-like control system wherein the messages allow the central controller system to override the selection of states for the redundant elements made by the peer-to-peer-like control system.
Claims39
A control system for a device having a plurality of redundant elements wherein each redundant element has an active state and a standby state, the control system comprising:
- a peer-to-peer-like control system that is operative to select the active and standby states of the redundant elements and that comprises a plurality of control components wherein a first control component is associated with a first redundant element and a second control component is associated with a second redundant element;
- and
- a central controller system that is operative to send messages to the first control component and the second control component wherein the messages allow the central controller system to override the selection of states for the redundant elements made by the peer-to-peer-like control system.
A control system for a network system having a plurality of redundant elements wherein each redundant element has an active state and a standby state, the control system comprising:
- a peer-to-peer-like control system that is operative to select the active and standby states of the redundant elements;
- and
- a central controller system that is operative to send messages to the peer-to-peer-like control system wherein the messages allow the central controller system to override the selection of states for the redundant elements made by the peer-to-peer-like control system.
A system comprising
- a first redundant component that is operative to provide a first function used by other components in the system, the first redundant component having an active state in which it provides the first function and a standby state in which it does not provide the first function;
- a second redundant component that is also operative to provide the first function, the second redundant component also having an active state in which it provides the first function and a standby state in which it does not provide the first function;
- a first control component associated with the first redundant component and a second control component associated with the second redundant component wherein the first control component cooperates with the second control component to determine which of the first redundant component and the second redundant component should be commanded to enter the active state and which should be commanded to enter the standby state;
- and
- an override mechanism that is operative to command one of the first redundant component or the second redundant component to enter the active state wherein the redundant component commanded to enter the active state will enter the active state even if the first control component and the second control component had previously commanded the redundant component to be in the standby state.
A system comprising
- a first redundant component that is operative to provide a first function used by other components in the system, the first redundant component having an active state in which it provides the first function and a standby state in which it does not provide the first function;
- a second redundant component that is also operative to provide the first function, the second redundant component also having an active state in which it provides the first function and a standby state in which it does not provide the first function;
- a peer-to-peer-like control system that is operative to select the active and standby states of the redundant elements;
- and
- an override mechanism that is operative to send messages to the peer-to-peer-like control system wherein the messages allow the override mechanism to override the selection of states for the redundant elements made by the peer-to-peer-like control system.
A method for controlling the states of a pair of redundant elements wherein the redundant elements have an active and a standby state, the method comprising the steps of:
- commanding the first redundant elements to enter an active state and commanding the second redundant element to enter the standby state using a peer-to-peer-like control system;
- and
- overriding the selection of states made by the peer-to-peer-like control system using a central control element wherein the first redundant element is commanded to enter the standby state and the second redundant element is commanded to enter the active state.
