Abstract
An improved system, method, and computer-readable instructions for scheduling, transporting, and receiving inbound packets efficiently in networks with cyclic packet scheduling is provided. The method provides for scheduling upstream packet transmission slots for each node in the network so that the spacing between the packet transmission slots is reduced; for each node in the network, if there is a locally originated packet of the node to be transmitted upstream, selectively activating a forwarding buffer to receive and temporarily store a packet received from a neighboring downstream node during upstream transmission of a locally originated packet of the node; and upon completion of the upstream transmission of the locally originated packet, transmitting upstream the packet stored in the forwarding buffer.
