ABSTRACT:
A communication system for the transfer of small digital message blocks and large digital message blocks. A plurality of nodes are coupled to a common wideband communication channel capable of facilitating the transfer of small digital message blocks and large digital message blocks. One of the nodes is a master node controlling the communication of the communication channel by selectively polling the other of the plurality of nodes. The communication system has a first protocol for the transmission of small digital message blocks and a second protocol for the transmission of large digital message blocks. The master node establishes a polling priority for each of the plurality of nodes and polls those with a higher polling priority more frequently than those with a lower polling priority. The master node allows the one node being polled to communicate over the channel of either a small digital message block or a large digital message block. Further the master node adapts the polling priority for each of the nodes based upon a predetermined algorithm.
