  • Patent number: 5477530
    Abstract: First and second multi-node communication paths are connected via a bridge node. Each path employs a quota allocation scheme for access thereto by the nodes thereon. A first quota allocation signal is propagated on the first path and a second quota allocation signal is propagated on the second path, the second signal controlling access to the second path for the purpose of transmitting information to the bridge node destined for the first path. The quota allocation signals are synchronized to ensure that there is at most one circulation of the second quota allocation signal for each circulation of the first quota allocation signal. Information from the first path to the second path is deflected from the bridge node and around the first path if the bridge node is full. If the information is transmitted in sequenced packets, a deflected packet is assigned a deflection number. The bridge node tracks deflections via the deflection numbers.
