Each end node has, beside a unique address, a configurable address that can be updated via some configuration means from a control entity. The unique address is a dedicated address. Different end node can have the same configurable address. The sender of a message or packet must be aware of the used addresses in the system. The technique does not require any changes to the normal data communication protocol. The messages or packets are unchanged. The implementation is done on the sender side and in the end node. Each message or frame or packet contains only one address. Each message and packet is received by each end node. A message is used by an end node if the unique or configurable address is matching. Beside that there is a possibility that the filtering is done by a hub that is selecting the right end node according the port definition (each output port has a dedicated unique address and configurable address). Moreover, the shared image frame has been sent once by the sender, which results in lower power consumption and less load on the sender. | 05-14-2009 |
