Abstract: A method for receiving data is provided. Multiple packages are received according to a sliding window W(N). If a starting package of the packages is received successfully, the W(N) is slid to a W(N+1). If a non-starting package of the packages is received successfully, the corresponding counter is activated for counting. If the starting package of the packages is not successfully received and part of multiple counters counts to an up-limited value, the W(N) slides to the W(N+1). Other packages are continuously received according to the W(N+1), and whether the block sequence numbers (BSNs) of the counters located in the overlap area between the W(N) and the W(N+1) are determined. When at least one BSN to which at least one counter corresponds is not located in the overlap area, the at least one counter corresponding to the at least one BSN not located in the overlap area is reset.

Abstract: There are disclosed processes and apparatus reordering packets. The system includes a plurality of source processors that transmit the packets to a destination processor via multiple communication fabrics. The source processors and the destination processor are synchronized together. Time stamp logic at each source processor operates to include a time stamp parameter with each of the packets transmitted from the source processors.

Abstract: Data communication in network traffic is modeled in real time and is analyzed using a 2-state Markov modified Poissen process (MMPP). The traffic inter-arrival times for bursty and idle states define a transition window [?1max, ?2min] represented by the boundary values ?1max for the inter-arrival time for bursty traffic, and ?2min for the inter-arrival time for idle traffic. Changes in the values of ?1max and ?2min are tracked over time, and the size of the transition window is enlarged or decreased based upon relative changes in these values. If the inter-rival times for the bursty state and the idle state become approximately equal, the model defaults to a single state model. The modeling is applicable to the synchronization of polling and blocking in a low-latency network system. This permits the adoptive selection of poll or block to maximize CPU utilization and interrupt latency.

The packet is transmitted from the node towards the destination address only if the addresses are identical or the source address belongs to the set of allowed packet data addresses.
