ABSTRACT:
A method and corresponding apparatus is provided for determining the location of a configuration server being connected to a totally symmetric network infrastructure that does not exhibit any symmetry breakers on network level. The configuration server reaches a decision to determine its network-wide unique configuration in order to be able to serve controllers. This decision depends on the plug position of the configuration server under consideration and the assumption of plugging rules governing a “good” network infrastructure. The controllers periodically send network packets that will be marked if they traverse specific connection elements in the network. The origin and the path of a network packet can be determined. The decision making is based on a majority function based on the packets received by the configuration server. If a decision cannot be made, then errors in the cabling structure can be detected.
