ABSTRACT:
The present invention provides for dynamically determining a ratio of forwarded packets to injected packets to be transmitted in a bus ring. At least one forwarded packet is received into a first queue. An injected packet is received into a second queue. A determination, or snapshot, of the number of forwarded packets in the first queue due to the presence of the injected packet in the second queue is triggered. Packets corresponding to the snapshot are transmitted. After the packets are transmitted, if there is another injected packet stored in the second queue, another snapshot is performed. Packets corresponding to this snapshot are transmitted, and so on.
