Abstract
A method for operating a communication network, in which the states of the hardware units in the communication network are ascertained and information about assignments of the communication links to the hardware units is used to determine the states of the communication links.
Claims15
A method for operating a communication network, the method comprises:
- storing in, at least one memory device, of a control device first information about an assignment of communication links to hardware units forming a communication network,
- wherein at least one control device controls data transmission over communication links via assigned hardware units,
- wherein each communication link is determined by a physical path in the transmission network that extends from a source of the data to a sink of the data;
- ascertaining states and/or state changes of the hardware units;
- transmitting second information about the states and/or state changes of the hardware units to control devices, wherein the data transmission via the communication links is handled by the assigned hardware units;
- and
- determining states of the communication links on a basis of the first information and the second information.

A method for operating a network, which comprises:
- storing, in memory devices, information about an assignment of communication links to hardware units forming a communication network, the hardware units used for data transmission via the communication links;
- ascertaining states and/or state changes of the hardware units;
- transmitting information about the states and/or the state changes of the hardware units to control devices;
- determining states of the communication links on a basis of the states of the hardware units used for the data transmission via the communication links by processing the information about the assignment of the communication links to the hardware units in the control devices;
- describing a hardware unit by a sub-state for assuming various values in accordance with a severity of a fault in an operation of the communication network, the sub-state depending on a state of the hardware unit;
- using information about a value of the sub-state corresponding to a most severe fault in the operation of the communication network for determining a state of a communication link;
- and
- transmitting, of the values currently ascertained of the sub-state, only information about the value of the hardware unit corresponding to the most severe fault in the operation of the communication network to the control devices.
