Transfer of Streaming Measuring Information with Aging in the Channels of a Testing Ground SDN for Testing of Aircrafts

Abstract

The current article considers the use of channels in transferring measurement data frames in the network controlling the condition and movement of robotic complexes. Real-time mode is used to exclude measurement data frames according to the aging threshold. Analytical correlations are given for determination of exponentially conditional density of the probability distribution as well as frame transfer time distribution functions taking aging into account. The article contains an example of a real-time computer system with data aging. Analytical ratios are given for the aggregated channels when working in parallel mode. Transfer of frames of measurement data is carried out in parts taking into account the threshold of aging. The mode of simultaneous transfer of duplicated frames by subchannels for exponential time is considered. The continuation of the transfer process resumes when the first frame is received. The processing of the measurement data is done in switches of the Software Defined Network (SDN).
