摘要： In an interactive video-on-demand system, real-time programs are encoded as a transport stream including a plurality of transport stream packets. Some of the transport stream packets include timing signals indicating the real time of the program. The transport stream packets are formatted into transport cells for transport over an asynchronous transfer mode network from a source to a destination. The cells are transported at a transport rate which is determined by a network clock. The transport rate is chosen to deliver the transport stream faster than the real time of the program. While transporting the transport stream, it is determined if the transport stream is being transported ahead of the real time of the program. In this case, idle cells are injected into the transport stream to have the program arrive at the destination in the real time of the program.

摘要： A method and apparatus for transferring data units between a host memory and a peripheral interface, the data units being subject to a flow control mechanism whereby some of said data units are flow controlled and some of said data units are not. Two transmit buffer memories are coupled to the peripheral interface; one for storing controlled data units to be transferred to the peripheral interface and the other for storing uncontrolled data units to be transferred to the peripheral interface. A single request buffer stores successive requests for data to be transferred from a host memory to either of the two transmit buffer memories. Data transfer circuitry transfers data from the host memory to either of the two transmit buffer memories in response to the requests stored in the request buffer. The data transfer circuitry is prevented from transferring further data from the host memory to the transmit buffer memory storing the controlled data units when it is determined that there is not enough room in the transmit buffer memory storing the controlled data units to accommodate another data unit. The data transfer circuitry is allowed, however, to transfer further data from the host memory to the transmit buffer memory storing the uncontrolled data units.

摘要： In a network node having a host system coupled to a network by an adapter, VC-specific congestion is detected and reported to the host system. The host memory includes rx slots or buffers, each corresponding to one of one or more supported slot types. Per-VC slots consumed counters are maintained to count slot consumption for each active VC. Free buffer FIFOs are maintained for each of the one or more slot types, which have a predetermined congestion threshold associated therewith. Entries in each free buffer FIFO correspond to an rx slot posted by the host system. When a new rx slot or buffer in host memory is to be allocated to an incoming cell received on a given VC, the slots consumed counter is compared to the predetermined congestion threshold. If they are equal, the VC is at threshold level and the incoming cell is discarded and a report is sent to the host system. If the slots consumed counter is below threshold, a new rx slot is allocated for the reception of the data and the slots consumed counter is incremented. If the VC is credit-based flow control enabled and the slots consumed counter is below threshold, a credit is returned. If the VC is credit-based flow control enabled and the slots consumed counter is greater than or equal to the threshold, the credit return is deferred until the counter falls below threshold.

摘要： A status report frequency mitigation mechanism for mitigating the frequency of status report generation for raw cells during transmit operations in a network node is presented. The status report frequency mitigation mechanism operates to adjust the frequency with which status reports for raw cells are generated by manipulating the End-of-Packet (EOP) bit in transmit slot descriptors associated with transmit slots containing raw cell data.

摘要： The present invention provides multiple grade, composite cemented carbide articles and a method of making such articles. The cemented carbide articles comprise carbides of different grades (or different compositions and/or microstructures) and, therefore, correspondingly different properties at different locations in the same article. The method of the present invention comprises filling different areas or portions of a die with metallurgical powders having different compositions and/or microstructures. The powder is then compressed as a single compact in the die cavity. The compressed compact is subsequently sintered to produce a multigrade cemented carbide article having composition and/or microstructural variations within the volume of the article.

摘要： A mechanism for avoiding an initiation of control read transactions on a system bus coupling a host system having a host memory and an interface connected to a peripheral unit as data is moved between the host system and the peripheral unit is presented. Control information associated with data memory portions in host memory is written to the interface for data memory portions storing outgoing data and data memory portions to receive incoming data. The interface includes a controller to move data between the host memory and the interface by first obtaining the control information for the associated data portions. The interface writes status reports in association with the movement of data between the interface and the host memory via the system bus. The mechanism thus enables data transfers to occur via the system without the initiation of control reads in absence of an exception condition.

摘要： An apparatus and method for transferring data from a source memory (e.g. a host memory) to a peripheral interface via a bus utilizes a transmit buffer memory coupled to the peripheral interface, and a current time counter advancing at the rate at which data is to be transferred from the transmit buffer memory to the peripheral interface. A schedule table data structure stores entries in some or all of its locations, where each location corresponds to a point in time at which data is to be transferred from the transmit buffer memory to the peripheral interface. A schedule table pointer is used for pointing to successive locations in the schedule table. The schedule table pointer advances at a rate faster than the current time counter advances so that the schedule table pointer represents a point in time which is ahead of the point in time currently output by the current time counter. A data transfer is initiated from the source memory to the transmit buffer memory via the bus when a valid entry is stored at the location in the schedule table pointed to by the schedule table pointer. The data is then transferred out of the transmit buffer memory to the peripheral interface when the current time counter reaches the value representing at least the same point in time that was represented by the schedule table pointer when the data transfer was initiated. Data transfers from the transmit buffer memory are thereby synchronized in time with their corresponding entries in the schedule table.
