Abstract: Apparatus (110) for configuring network equipment or devices (101a-101n) during runtime is particularly applicable to network equipment based on QorIQ (trade mark) communication platforms for DPAA (Data Path Acceleration Architecture) optimization purposes and provides a way maintaining an optimal configuration which can change over time acccording to real traffic conditions. The invention may be implemented with any kind of adaptation algorithm for targeting different DPAA features. A flow characteristic function is determined from collected traffic statistics for a multiplicity of traffic flows classified by a common property such as protocol or destination or source. Flow properties are characterised over time, past present and future prediction and in relation to other existing flows based on assigned priorities. A computed flow characteristic function represents the basis for all adaptation algorithms which may be implemented in order to optimise the various DPAA features. In contrast with conventional methods which adapt traffic to system constraints, the apparatus of the present invention itself continuously adapts to traffic dynamics in order to maintain an optimal configuration over an extended period of time.

Abstract: A method and apparatus for deriving a packet select probability value for a data packet. The method comprises determining a queue length value for a target buffer of the data packet, calculating a queue congestion value based at least partly on the queue length value and a packet select queue length range, and calculating the packet select probability value for the data packet based at least partly on an exponential function e−x, where x is computed based at least partly on the queue congestion value.
