    摘要： Serial storage interface apparatus for coupling a serial storage mechanism, such as a charge coupled storage device or a magnetic bubble storage device, to a data processor input/output (I/O) bus. Speed control circuitry is provided for causing the serial storage mechanism to operate at a higher speed when the data processor is responding more rapidly to data transfer requests from the interface apparatus and at a lower speed when the data processor is responding less rapidly to data transfer requests from the interface apparatus. This speed adjustment feature reduces the amount of data buffering required for interfacing a serial storage mechanism to an asynchronous variable response time I/O bus system.

    摘要： A system for providing flexible billing in a cable environment can establish billing practices based on tier level of service, quality of service or the amount of network resources consumed. A plurality of tiers or levels of service can be defined by parameters including at least a maximum or peak bit rate or bandwidth for providing services over a shared channel. A plurality of levels or tiers of services are defined by maximum bandwidth or bit rate and a subscriber receives service at that subscribe-to level or at a slower data rate depending on availability of shared bandwidth. Quality of service is maintaining the specified bandwidth, jitter or delay. The amount of network resources consumed may be expressed in terms of the amount of data transmitted or the connect time of a network access device to the network.

    摘要： In a two way cable system that includes a controller and a plurality of user terminals, a method of granting rights for upstream data transmission from the user terminals includes processing contention requests to generate contention grants and maintaining a list of connections, each connection having specified therefor a predetermined bit rate. The controller sends a downstream data stream to the user terminals and receives an upstream data stream from the user terminals. The downstream data stream includes a plurality of grant fields, and the upstream data stream includes upstream data slots and upstream control slots. The method further includes scheduling preemptive grants for upstream data slots using selected fields of the plurality of grant fields so as to provide preemptive grants for upstream data transport at a bit rate specified for each connection, sending to the user terminals a data transmission grant in a grant field of the plurality of grant fields for which a preemptive grant is scheduled, and sending to the user terminals a data transmission grant in a grant field of the plurality of grant fields in which a contention grant is pending and no preemptive grant is scheduled.
