Apparatus and method use pre-order queuing and scheduling. Reordering of the transmission sequence of packets that could be sent out in one round is allowed according to the quantum consumption status of the flow within the round. Per-packet time complexity is maintained independent from an increase in flow number and packets of variable-length are processed.

Method and apparatus for scheduling for packet-switched networks

A message scheduler uses two thresholds to place cells into a queue. One determines, for a non-full queue, where to place high-delay-priority cells in relationship to low-delay-priority cells, and the other determines, for a fall queue, which low loss-priority cells to push out to make room for a high-loss-priority cell.

A shared memory based network having a transferring network switch and a receiving network switch. In this network, each network switch has a stack, queues corresponding to output ports and a dared control port. The stack stores available buffer addresses of the shared memory. Each of the queues stores to-be-accessed buffer addresses of the corresponding output port. The shared control port is driven to indicate states of the shared memory based network, so that th stack of the transferring network switch is identical with the stack of the receiving network switch. The shared memory can be read by all output ports of both the transferring network switch and the receiving network switch according to their corresponding queues.

An ultrasonic system is provided for measuring the thickness of steel plates used in the bottom of oil storage tanks and other similar applications. When the bottom plate corrodes, the potential for leakage occurs. The ultrasonic system can be used to monitor the corrosion of bottom plates in areas which are generally inaccessible, such as the bottom of oil storage tanks. The ultrasonic system includes a probe drive frame having multiple brackets for supporting a plurality of ultrasonic probes. A pulse generator and multi-channel scanner are connected to the probes. A processing unit reads and processes the signals from the probes to calculate the thickness of the plate and to warn of potential leakage problems caused by corrosion of the plate. The system can be operated from a remote location outside the oil storage tanks, which minimizes the time and expense in monitoring the plate.
