Method of and apparatus for sorting data flows based on bandwidth and liveliness

摘要

A method of and an apparatus for sorting data traffic based on a predetermined priority such as a bandwidth and a liveliness is provided. The method includes operations of: receiving the data flows; sorting the data flows based on bandwidth by defining a plurality of bandwidth ranges and classifying the sorted data flows according to the bandwidth ranges to which the bandwidth of each data flow belongs; and sorting the classified data flows based on liveliness representing frequency of occurrence of the data flows. The sorting of the classified data lows determines that the data flow which is recently received has the higher liveliness and sorts the data flows based on the determination. The method and apparatus facilitates selecting data flows which are possible hostile attack attempts from a vast amount of data traffic and allowing selective and intensive monitoring of the selected data flows.
