Abstract: The invention is directed to a method and system for efficiently distributing Inverse Multiplexing over ATM (IMA) filler cells on IMA logical links having inactive or unusable IMA sub-links. Inactive IMA sub-links are identified during round-robin distribution of ATM data cells to active IMA sub-links. Predefined IMA filler cells are transmitted simultaneously on the identified inactive IMA sub-links when an ATM data cell is transmitted on an active IMA sub-link, thereby reducing the delay between transmitting ATM data cells.

Abstract: A method and apparatus for statistical compilation is presented. A statistic component portion for each statistic is stored in each a plurality of banks in a multi-location memory. At least one statistical update stream is received. Each statistical update stream includes a plurality of statistical updates, where each statistical update includes a statistic identifier and an update operand. Received statistical updates are scheduled to produce a scheduled update stream. A control block executes the updates. The control block retrieves the current value of one of the statistic component portions from memory and combines the current value with the update operand of a corresponding statistical update. The resulting updated component value is then stored back into memory. When a processing block issues a statistic request, the control block fetches each of the component portions from memory and combines the component portions to produce a total statistic value.

Abstract: A method and apparatus for statistical compilation is presented. The statistical compilation circuit includes a multi-bank memory that stores a plurality of statistics, where a statistic component portion for each statistic is stored in each of the plurality of banks in the multi-bank memory. An arbitration block is operably coupled to receive at least one statistical update stream. Each statistical update stream includes a plurality of statistical updates, where each statistical update includes a statistic identifier and an update operand. The arbitration block schedules received statistical updates to produce a scheduled update stream. A control block operably coupled to the arbitration block and the multi-bank memory executes the updates included in the scheduled update stream. The control block retrieves the current value of one of the statistic component portions from one of the memory banks and combines the current value with the update operand of a corresponding statistical update.
