    摘要： A process for the recovery of sulfur from an acid gas stream is disclosed. The process includes a Claus sulfur recovery step in combination with a direct reduction step and a biological sulfur recovery step to provide a sweet gas stream having a very low concentration of hydrogen sulfide and sulfur dioxide. The process includes reacting an acid gas steam with oxygen under such oxidation conditions to yield a combustion gas comprising hydrogen sulfide and sulfur dioxide. The combustion gas is reacted under Claus reaction conditions to yield a reaction gas comprising sulfur. Sulfur is recovered from the reaction gas to yield a Claus tail gas comprising hydrogen sulfide and sulfur dioxide. The Claus tail gas is reacted under direct reduction reaction conditions to yield a direct reduction gas comprising sulfur. Sulfur is recovered from the direct reduction reaction gas to yield a tail gas comprising a concentration of hydrogen sulfide. The direct reduction tail gas is contacted with a lean absorbent to thereby remove from the tail gas a portion of the hydrogen sulfide contained therein and to yield a sweet gas and a rich solvent comprising dissolved hydrogen sulfide. The dissolved hydrogen sulfide of the rich solvent is biologically oxidized to elemental sulfur by contacting the rich solvent with sulfur bacteria under suitable biological oxidation conditions.

    摘要： A method for easing data transmission congestion in a switch device having a plurality of ports. The switch device includes a shared buffer capable of dividing into a plurality of buffering units. The method comprises the steps as follows. A plurality of output queues are provided, in which the output queues have a one-to-one correspondence with the ports, and each output queue has a number of reserved buffering units. The buffering unit(s) are then assigned in the shared buffer. A packet is received from a source port and storing the packet in an assigned buffering unit. The target port of a packet is determined according to a header of the packet. Then, the buffering unit containing the packet is linked to the output queue that corresponds to the target port. The free buffering units are thus controlled according to a number of reserved buffering units in the output queue and a triggering or a terminating condition of the source port.

    摘要： A output queuing method for forwarding the packets sequentially in a switching network. Each port is related to a port output queue and a global output queue is shared by all port output queues. A FIFO (First In First Out) block is allocated into each port output queue and the global output queue. The FIFO block contains a number of FIFO nodes. Based on the type and destination ports of the received packet, the fields of the related FIFO node in the port output queue and the global output queue are set. The packets are sent out or skipped based on the related fields.

    摘要： A method for transmitting multi-cast packets is provided, including the steps of (a) receiving a plurality of multi-cast packets and generating corresponding port masks to indicate a plurality of ports from which the multi-cast packets are to be transmitted, (b) selecting, based on the yet-enqueued ports indicated in port masks, a port with highest priority, enqueuing the multi-cast packet into the port, and updating the port masks, (c) checking whether the port with highest priority being full-duplex, and (d) determining when to repeat steps (b) to (d) base on the result of the checking, until finishing the transmission specified by the port masks. In step (d), when the port with highest priority is full-duplex, wait until the port with highest priority starting transmitting the packet, then repeat steps (b) to (d). On the other hand, when the port with highest priority is half-duplex, wait until the port with highest priority transmitting a certain portion of the packet, for example 64 bytes or 128 bytes, then repeat steps (b) to (d). This will repeat until finishing all the transmission specified by the port masks. Preferably, the port with highest priority means the port of the highest priority group with the shortest output queue. When finishing all the transmission specified by the port masks, the switch will release all the related buffers of the multi-cast packets.

    摘要： A method for performing a MAC address lookup in a network switch of an Ethernet network is provided, using a memory structure including a number of multi-slot buckets. Each of the multi-slot buckets is mapped to a hash key derived from a MAC Address. Each of the multi-slot buckets has a number of forwarding table section, each storing a number of the forwarding table entries. If two forwarding table entries are stored in each forwarding table section of a 4-slot bucket ¼ memory space and ½ access time can be saved. Thus, the lookup for the forwarding table according to the MAC address in the Ethernet switch IC can be effectively performed.

    摘要： The present invention constructs a SD Flash card by plugging two micro-SD cards into a new apparatus that has the same form factor as a SD Flash card. In this new apparatus, there is a controller to bridge the two micro-SD cards of any SD interface speed type (DS, HS, UHS50 or UHS104) to UHS104. The controller performs striping access function to achieve almost double performance in sequential read/write throughput if it is not limited by the target SD interface speed.
