Abstract

In a communication system, a network has nodes each connected in a star relationship to a number of end units that include a device for assuming one of an idle, active, or on-line state and for requesting the node to which it is connected to change it from the idle to the active and the active to the on-line state, and for releasing the on-line state on the basis of data at the end unit. The nodes for change the state of an end unit from the idle to the active and from the active to the on-line mode on the basis of available communication time. According to an embodiment of the invention, the nodes change the states to the on line state on the basis of policy preferences for the type of traffic, and specifically to grant priority to stream traffic over batch traffic.
