1. A method of preparing data for transmission, comprising:

  • obtaining connections to at least two networks which are at least partially in parallel and which differ in their respective security characteristics;

    receiving data packets in a first collection of data packets;

    receiving data packets in a second collection of data packets;

    treating each of the data packets of the first collection with a supplemental security measure which corresponds to a difference in respective security characteristics of a first network, namely, the internet, and a second network, namely, a private network, wherein the supplemental security measure for treating a data packet includes at least encrypting data in the data packet according to a security policy;

    submitting the encrypted data packets of the first collection for transmission over a first path over the internet; and

    submitting the data packets of the second collection for transmission over a second path through the private network, without treating the data packets of the second collection with the supplemental security measure;

    wherein transmission of the data packet collections utilizes the networks, which are at least partially in parallel and which differ in their respective security characteristics, and data packets to be transmitted over one of the networks have been treated before their transmission over that network with a security measure which is not applied before transmission to data packets that are to be transmitted over another network.
