In terms of network management or TE (Traffic Engineering), it is favorable to detect change trends immediately after flow changes are induced. In this work, an R/S analysis based Pox Diagram was made use of to detect the change trends. In case an abrupt change appears within a normal flow, a dispersion occurs in the Pox Diagram. To evaluate the dispersion the upper-most part and the lower-most part of plots group of a Pox Diagram were characterized into slopes as $H_{Sup}$ and $H_{Inf}$. With the time-dependent $H_{Sup}$ and $H_{Inf}$, namely $H_{Sup}(t)$ and $H_{Inf}(t)$, change points were successfully detected, thus supporting the preset proposal. The replacement of $H_{Sup}(t)$ and $H_{Inf}(t)$ were performed around every 0.5s, which appeals a real time application. |
