METHOD FOR REDUNDANTLY AND SECURELY TRANSFERRING DATA FROM A DATA SOURCE TO A DATA SINK

摘要

Method for transferring data from a data source (1) to a data sink (2) and/or vice versa via at least two transmission links (5, 6) that operate independently of one another and wirelessly. A splitter (3) is supplied with the data from the data source (1) and the splitter (3) supplies the data to the at least two transmission links (5, 6). Also, the data transferred via the two transmission links (5, 6) are supplied to a combiner (4) and the combiner (4) forwards the received data to the data sink (2) on the basis of prescribed criteria. The invention is characterized in that the transfer of the data between the data source (1) and the data sink (2) and/or vice versa takes place with a different time response on the at least two wireless transmission links (5, 6) while the parallel redundancy protocol (PRP) is applied.

1. A method of transferring data between a data source and a data sink, the method comprising the steps of:
feeding data of from the data source to a splitter; feeding the data in two streams from the splitter via to at least two respective wireless transmission paths operating independently of each other to a combiner; forwarding with the combiner the received data to the data sink in accordance with specified criteria; and imparting to the data being transferred between the data source and the data sink different time behaviors on the at least two wireless transmission paths, according to a Parallel Redundancy Protocol.
