    摘要： The present invention provides a multi-service queuing method and apparatus that provides exhaustive arbitration, load balancing, and support for rapid port failover. Routers and switches according to the present invention can instantaneously direct the flow of traffic to another port should there be a failure on a link, efficiently handle multicast traffic and provide multiple service classes. The fabric interface interfaces the switch fabric with the ingress and egress functions provided at a network node and provides virtual input and output queuing with backpressure feedback, redundancy for high availability applications, and packet segmentation and reassembly into variable length cells. The user configures fixed and variable-length cells. Virtual input and output queues are coupled to a switch fabric. Statistics regarding the virtual input and output queues are collected and packet queuing for the virtual input and output queues is controlled using the collected statistic to provide congestion control for the virtual input and output queues and the switch fabric.

    摘要： A system and method for programming a programmable circuit. A graphical interface is provided to allow a user to graphically define at least one type of input data unit that is expected to be received at the programmable circuit. A visual representation of the input data format corresponding to the defined type of input data unit is presented to the user. The user graphically manipulates the visual representation of the input data format to graphically transform the input data format to a visual representation of a desired output data format of output data units to be output from the programmable circuit. Program code is automatically generated for directing the programmable circuit at run-time deployment to transform actual input data units of the defined type of input data units to actual output data units having the desired output data format in a manner corresponding to the graphical transformation of the input data format to the desired output data format.

    摘要： A system and method for scheduling data utilizes a number of queues for receiving data. A programmable criteria table comprises a number of entries each associated with one of the queues. The entries of the criteria table comprise programmable traffic parameters selected to associate the queues with particular traffic characteristics governing a flow of data through the queues. A programmable mapping table maps each of the queues to one of the criteria table entries. The criteria table is programmable independently from the mapping table. A scheduling period timer produces epoch time signals that define scheduling time periods. The scheduling of queues changes between scheduling time periods in accordance with the traffic parameters associated with the queues. The scheduling time period is dynamically programmable. The traffic parameters are dynamically programmable to alter a scheduling prioritization of the queues.

    摘要： An implantable medical device system includes an implantable device and an external locator device for percutaneously locating detecting port opening of the implantable device. The implantable device includes a port chamber forming the port opening, a septum sealing the port chamber relative to an exterior of the device, and a coil positioned at a known location relative to the port opening. The locator device includes a controller, at least one X-loop electrically coupled to the controller and oriented along a first major axis, and at least one Y-loop electrically coupled to the controller and oriented along a second major axis differing from the first major axis. The system is configured such that when the locator is spatially proximate the coil, an induced voltage in at least the Y-loop(s) is read by the controller to indicate a location of the coil relative to the locator device.

    摘要： A system and method for policing individual flows and subflows of a data stream. Data traffic streams are classified into separate traffic flows, which in turn can be further classified into subflows, thereby providing for different priority levels of subsets of the flow. The subflows may be still further classified into additional subflows, creating a hierarchical, layered prioritization that can be metered at each vertical and horizontal level of the hierarchy. A packet flow rate of each of the subflows is compared to a predefined rate limit to allow subflows of a flow to have different priorities therebetween.
