Systems and methods of managing power consumption provide for placing a processor in a non-snoopable state while a storage interface associated with the processor is enabled for bus mastering. Such data access can be facilitated as a layer adjacent to or part of an MES system or as a white box cooperating to encapsulate data such as in the controller or the MES layer, for example. Also, a controller determines whether the broadcast message has load balancing information for the first service network and a second service network, and in response to the broadcast message having the load balancing information, generates a random number and determines whether the random number belongs to a restricted priority level according to the load balancing information.
