20100195671 | SYNCHRONIZATION OF TWO COMMUNICATION NETWORKS OF AN ELECTRONIC DATA-PROCESSING SYSTEM - A method for synchronizing two communication networks of an electronic data-processing system, each of the networks including one or more respective nodes, may include establishing for each of the networks a respective time schedule that establishes at least one respective time slot for a respective synchronization message. The synchronization message time slots are established to coincide. The synchronization message of the first communication network is generated by one of the nodes of the first communication network. The synchronization message of the second communication network is generated as a function of the synchronization message of the first communication network. | 08-05-2010 |

One or a plurality of nodes is connected to the two communication networks in each case. Each of the two communication networks has a schedule, which specifies at least one time slot for a synchronization message. One of the nodes of the first communication network, and one of the nodes of the second communication network are linked to one another by a shared arithmetic unit. A deviation between the time slots for the synchronization messages on the two communication networks is determined as a function of the schedules of the two communication networks. The deviation is used to determine correction values, which are forwarded to at least one other node. The occurrence of the time slots for the synchronization messages is modified by the other node as a function of the correction values. | 08-12-2010 |
