2014 2014 52nd Annual Allerton Conference on Communication, Control, and Computing (Allerton)  
As the Internet moves into the era of big network data, it presents both opportunities and technical challenges for traffic measurement functions, such as flow cardinality estimation, which is to estimate  ...  We also consider the problem of differentiated estimation that gives flows of high priorities better precision in their cardinality estimations.  ...  A more direct comparison is given in Figure 7 , which shows that the standard errors for high-priority flows are about half of the errors for the base-priority flows when the flow cardinalities are beyond  ...
