Abstract
A network statistics processing device comprises a port processing unit for determining an update from a forward statistic metric carried by an input PDU, an arbitration unit for placing the updates into a scheduled stream of updates, and a memory unit for storing statistic totals relating to the network operating parameters. The port processing unit also processes the statistic results retrieved from the memory into reverse statistic metrics that are inserted into an output PDU. A statistics monitoring and processing unit enables performance of high level statistical processing on selected updates and on the results. A method of generating and maintaining statistic totals on a plurality of network operating parameters is also described. This arrangement reduces backplane traffic, provides the statistical ports with intelligence and so as to accommodate plural transmission protocols, and provides greater visibility into transactions that can occur on a network to provide debugging, flow and/or load information.
