The nature of the increasing network traffic has taken much more changes.In order to find out how these changes impact on the traffic character

we make a comprehensive analysis by using the traffic data collected with NetTurbo on an ISP WAN link.The result shows that compared to the previous analysis there are so many un-neglectable differences in the traffic characterization.More significantly

we found that despite its wide use

there is still much confusion regarding the identification of self similarity in recent real network traffic data and whether the self similarity still exists is uncertain

which is much more difference from the previous result.
