description

Bandwidth and consequently optimum overall efficiency of network system relies greatly on mechanism of packet management in IP routers. Our research objective is to implement rough set theory to minimizing number of the network system attributes responsible for decision making in selection of those packets, which improve its transmission. Such an approach is called priority queuing system model, as we assign priority to the packets selected, following rough set theory. Regardless of the file format, for all the routers, packets are transmitted in sequence one-by-one. Nonetheless, quality of streaming data largely depends on how much the packet loss is minimized, or eliminated at all, if possible, as it causes delays on wideband transmission line. The factors that impede the selection include destination port, service type, or the protocol. On having determined lower and upper bounds of set, we create decision tables which show the attributes such as IPv4 and IPv6 headers. As analytical methods do not reflect directly network stability study results, we decided to use graphical method of zero exclusion.
