Network manager and method

A network manager comprising:

• a data interface configured to communicatively couple to at least one radio access network (RAN) of a broadcast network (BCN) that is configured to wirelessly emit a load data signal, and to communicatively couple to a load data source network (LSDN);
• and
• a network controller communicatively coupled to the data interface and configured to receive request data with regard to a transmission of load data from the LDSN, to provide configuration proposal data defining at least one set of radio access network resources for transmission of the load data based on the request data, and to output the configuration proposal data as in response to the request data;
• wherein the data interface is configured to receive confirmation data in response to the configuration proposal data, the confirmation data referring to one set comprised in the configuration proposal data;
• and
• wherein the network controller is configured to provide configuration data based on the confirmation data to the at least one RAN, for the purpose of configuring the at least one RAN to use specific radio access network resources for transmission of the load data.
