Control for multimedia communication on local access table
First Claim
1. A communication system, comprising:
- a network having a plurality of nodes;
a plurality of end units each connected to one of said nodes;
means in each of said end units for assuming one of an idle, active, or on-line state and for requesting a node to which one of said end units is connected to change 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 one end unit; and
means in each of said nodes for changing the state of an end unit from the idle to the active and from the active to the on-line state on the basis of available communication time;
said node including means for transmitting and receiving data in time sectors, said time sectors each having an acquisition field for receiving acquisition requests and a traffic field for messages;
said end units directing requests for access to the on line state during the time of the acquisition field in the time sectors.

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.

7. A communication method, comprising:
-
directing communication traffic along a network to a plurality of nodes; directing the traffic from each node to a plurality of end units each connected to said nodes; requesting access to traffic with an end unit by assuming one of an idle, active, or on-line state and requesting a node to which it is connected to change 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; in said nodes changing the state of an end unit from the idle to the active and from the active to the on-line state on the basis of available communication time; directing traffic in said node includes transmitting and receiving data in time sectors, said time sectors each having an acquisition field for receiving acquisition requests and a traffic field for messages; and in said end units directing requests for access to the on line state during the time of the acquisition field in the time sectors. - View Dependent Claims (8, 9, 10, 11, 12)
