Abstract: A method of automatically identifying state information in different middlebox programs first identifies relevant program portions by expanding outward from a packet processing loop to statements dependent either by control or data dependency on that packet processing loop. Persistent variables in the statements are then collected and optionally winnowed by whether they are “used” or modified by those statements. The identified state variables may be segregated according to flow-spaces and/or output function so that a request for state data may be tailored precisely to the necessary state data greatly reducing network burden in state data transfer.

Abstract: A method and an apparatus for estimating direction of arrival of radar reception signal using antenna array extrapolation. Obtained is a transformation matrix representing a relationship between phases of reception signals received through ith to (N?2+i)th antennas and a phase of a reception signal received through (N?1+i)th antenna in a ULA antenna unit including N actual antennas. A phase of a virtual reception signal received through a new (N+i)th virtual antenna is generated by multiplying values corresponding to phases of the reception signals received through (i+1)th to (N?1+i)th antennas by the transformation matrix. A magnitude of the virtual reception signal received through the (N+i)th virtual antenna is obtained by averaging magnitudes of the reception signals received through ith to (N?1+i)th antennas.
