Abstract: A communication system includes a plurality of nodes connected in a daisy-chain via respective bus links. The plurality of nodes are configured for full-duplex, synchronized communication over the bus links for transmission of Ethernet frames within a flexible payload of superframes on the bus links. A node is configured to: determine that the node has a transmit token; transmit an Ethernet frame within a tunnel on the full-duplex bus links in at least one of an upstream direction towards a main-node or a downstream direction towards an end-sub-node; receive, while transmitting the Ethernet frame, a request for the transmit token from one or more other nodes in the tunnel on at least one of the full-duplex bus links in a direction opposite the Ethernet frame; and transmit the transmit token to a next node based on an order of priority of the one or more other nodes.
