METHOD FOR TIME-SYNCHRONISATION IN A COMMUNICATIONS NETWORK WITH A PLURALITY OF NETWORK NODES |
摘要 |
One or a plurality of sub-networks are defined in the communications network. Each of the sub-networks includes a plurality of network nodes from the communications network. One or a plurality of the sub-networks represent pre-determined sub-networks, in which respective pre-determined network nodes have both the function of a global slave node and the function of a local master node. The one or the other network nodes of the respective pre-determined sub-networks are local slave nodes. In addition to global synchronization using the global master node and the global slave nodes, local synchronization is also performed in the pre-determined sub-networks using the local master node and the local slave nodes. Thus, in the event of an error outside a pre-determined sub-network, the local synchronization may be continued, whereas the global synchronization is aborted. It is thus avoided that an erroneous synchronization is propagated into corresponding sub-networks. |
