Embodiments of the invention relate to routing promotion content files to groups of end node devices having the same or similar device attributes, such as data storage capacity, called transmission groups (420). Specifically, a promotion (410) is assembled into one or more data packages, with a package being created (430) for each different transmission group (440). Promotions may be aggregated, with multiple promotions being placed in each package (450). The packages may include information such as promotion identification, start time, end time, duration, port number, multicast or broadcast address to facilitate bulk data routing via broadcast or multicast. The packages are then used to generate and deliver promotion schedules to each device of a transmission group (420) and to schedule bulk data transmission (460) to the respective transmission groups via separate broadcast or multicast for each package. |
