Abstract:
1. A system comprising: a station circuit including a data layer and a transport layer, the station circuit capable of a source mode and a destination mode, the data layer of the station circuit in source mode disassembling a source packet into one or more source parcels and sending the one or more source parcels to the transport layer, the station circuit in destination mode receiving one or more destination parcels over a ring at its transport layer, reassembling the one or more destination parcels into a destination packet, and delivering the destination packet from the transport layer to the data layer; wherein the transport layer of the station circuit in source mode transmits the one or more source parcels over the ring and the transport layer of the station circuit in destination mode receives the one or more destination parcels over the ring; wherein each station circuit includes a command credit count with respect to each of the other station circuits on the ring and a parcel credit count with respect to each of the other station circuits on the ring; wherein a particular station circuit in source mode sends the source packet to a particular station circuit in destination mode if the command credit count of the particular station circuit in source mode with respect to the particular station circuit in destination mode is non-zero, and the parcel credit count of the particular station circuit in source mode with respect to the particular station circuit in destination mode is non-zero, and the particular station circuit in source mode reduces its command credit count with respect to the particular station circuit in destination mode by one and reduces its parcel credit count with respect to the particular station in destination mode by the number of parcels sent upon sending the source packet to the particular station circuit in destination mode.
