Recently, several Traffic Digest-based Network Monitoring schemes including, DATALITE, Proportional Union (PU) and the Quasi Maximum Likelihood approach (QMLE) have been proposed to support distributed Traffic Measurement and Analysis (TMA) for high-speed packet networks in general and network-wide Origination-Destination-pair-based Flow measurement estimation in particular. In these schemes, traffic flows defined by their O-D pair are mapped into a single Traffic Digest (TD) for measurement as they traverse through a monitoring point. It has been observed that the relative estimation error caused by such single-TD approach is significant for low-volume flows (mice) when they share the link with other large volume ones (elephants), which is quite common in practice.
