    Abstract: In order to enable dynamic scaling of network services at the edge, novel systems and methods are provided to enable addition of add new nodes or removal of existing nodes while retaining the affinity of the flows through the stateful services. The methods provide a cluster of network nodes that can be dynamically resized to handle and process network traffic that utilizes stateful network services. The existing traffic flows through the edge continue to function during and after the changes to membership of the cluster. All nodes in the cluster operate in active-active mode, i.e., they are receiving and processing traffic flows, thereby maximizing the utilization of the available processing power.

  • Patent number: 9236943
    Abstract: There is provided a method of eliminating an offset in a spot centroid due to crosstalk. A crosstalk matrix is used to characterize crosstalk characteristics of a multi-pixel spot-centroid detector. Left-multiplication of signals outputted from the multi-pixel spot-centroid detector, which are affected by the crosstalk, by an inverse matrix of the crosstalk matrix can result in a light-intensity-distribution signal with impacts of the crosstalk substantially removed. Based on this light-intensity-distribution signal, it is possible to derive the spot centroid, with the offset in the spot centroid due to the crosstalk substantially eliminated, resulting in an improved accuracy of the spot centroid detection, as compared with conventional methods.
