Abstract
A method of operating a transmission system (1) having a first network (2) and at least one second network (3) where data is exchanged between these at least two networks (2, 3) in that data of the first network (2) is fed to duplicating means (4), then is transmitted wirelessly to separating means (5) via at least two transmission paths (6, 7) by PRP, and is forwarded by the separating means (5) to the connected second network (3), characterized in that the data is transmitted via the first transmission path (6) as data packets and, if a data packet was not transmitted, this data packet is retransmitted via at least the second transmission path (7).
Claims4
A method of operating a transmission system having a first network and at least one second network where data is exchanged between these at least two networks in that data of the first network is fed to duplicating means, then transmitted wirelessly to separating means via at least two transmission paths by PRP, and is forwarded by the separating means to the connected second network, the method comprising the steps of:
- transmitting the data via the first transmission path as data packets and, if a data packet was not received,
- retransmitting the unreceived data packet via at least the second transmission path.
