Abstract

A method for time synchronization in a communication network comprising a multiplicity of network nodes, wherein synchronization messages are transmitted in the communication network and the synchronization message received in a slave node contains synchronization information for synchronizing the slave time of the slave node with the master time, i.e., synchronization messages are transmitted in a closed ring or line topology and the slave node receives first and second synchronization messages from different transmission directions, and wherein the slave node synchronizes a first time with the synchronization message from one transmission direction and a second time with the synchronization message from the other transmission direction.
