Abstract
The invention relates to, among other things, a method during which a network element (58, 60) of a data transmission network (50) is automatically integrated into a method for establishing a loop-free tree structure or is automatically removed from such a method. By taking preset criteria into account, it is ensured that no loops can arise in the data transmission network (50) when removing a network element from the method for establishing a loop free tree structure.
Claims13
A method for ascertaining a loop-free tree structure in a data transmission network, comprising:
- automatically including or removing a network element in the data transmission network based on at least one of the following:
- a number of additional network elements which are directly connected to the network element,
- detection of arrival or absence of data for ascertaining the loop-free tree structure, and
- allocation of the function to the network element in the loop-free tree structure.
A network element comprising a control unit which automatically involves or removes the network element in a method for ascertaining a loop-free tree structure, wherein the control unit operates according to:
- the number of additional network elements which are directly connected to the network element,
- detection of the arrival or detection of the absence of data for ascertaining the loop-free tree structure, and
- the function which is associated with the network element in the loop-free tree structure.
