1. A method for data transmission between at least one first network and at least one second network, wherein
a) for at least one data transmission between the at least one first network and the at least one second network, at least one connection between the first network and the second network is established and a datum or data is or are directed via a resource allocation unit arranged between the networks,
wherein
b) for the establishment of the at least one connection, the resource allocation unit exclusively allocates at least one network access resource, able to be coupled to the second network, and a one-way communication unit disposed upstream of the network access resource, for predefining a feedback-free data transmission direction.
