  • Stepwise quality-of-service scheduling method in output-buffered switches for broadband networks
    Patent number: 7164686
    Abstract: In a stepwise QoS scheduling method in output-buffered switches for broadband networks, packets are sequentially inserted in a sequence of windows on weight basis. The window size together with the weight of a flow determines the credits in a window for the flow. With sufficient credits, new packets are placed in the current window on a FIFO basis. Otherwise, packets are placed in an upward window being associated with sufficient accumulated credits.
    Type: Grant

  • Quality-of-service guaranteed media access control method with dynamic granularity control for local wireless ATM networks
    Publication number: 20030072289
    Abstract: In a quality-of-service guaranteed media access control method with dynamic granularity control for local wireless ATM networks, reservation bandwidth is allocated in accordance with a weight-based scheduling policy. Based on a neural-fuzzy prediction technique, the favorable bandwidth implying maximum throughput is derived. The smaller value between the reservation and the favorable bandwidth is allocated as the contention bandwidth of the frame.
