2020 SEP 14 (NewsRx) -- By a News Reporter-Staff News Editor at Information Technology Daily -- Research findings on Information Technology - Data Monitoring are discussed in a new report. According to news originating from Nanjing, People’s Republic of China, by NewsRx correspondents, research stated, “This paper focuses on solving the modeling issues of monitoring system service performance based on the network calculus theory. First, we formulate the service model of the smart grid monitoring system.”

Funders for this research include National Key Research and Development Program of China, BNRist Program, Tsinghua-Toyota Joint Research Institute Cross-discipline Program.

Our news journalists obtained a quote from the research from Hohai University, “Then, we derive the flow arrival curve based on the incremental process related functions. Next, we develop flow arrival curves for the case of the incremental process being a fractional Gaussian process, and then we obtain the generalized Cauchy process. Three technical theorems related to network calculus are presented as our main results. Mathematically, the variance of arrival flow for the continuous time case is derived. Assuming that the incremental process of network flow is a Gaussian stationary process, and given the auto-correlation function of the incremental process with violation probability, the formula of the arrival curve is derived. In addition, the overall flow variance under the discrete time case is explicitly derived. The theoretical results are evaluated in smart grid applications.”

According to the news editors, the research concluded: “Simulations indicate that the generalized Cauchy process outperforms the fractional Gaussian process for our considered problem.”
