Network Traffic Digesting (NTD) Software

Overview

The EMIST NTD (Network Traffic Digesting) Tool is an off-line network traffic analysis tool capable of analyzing both TCPDUMP [1] and Cisco NetFlow [2] export format traces in Windows. The EMIST NTD tool can detect the significant clusters, i.e., clusters whose traffic is greater than a threshold (either in terms of packet number or bytes) that is user-specified. The thresholds can be specified for in a unidimensional fashion (for source IP, destination IP, source port, destination port or protocol) and also in multidimensional fashion for the five-tuple. The EMIST NTD tool is functionally similar to the AutoFocus tool in [3]; however, it is significantly more computationally efficient. The detailed algorithms for both unidimensional and multidimensional clustering processes are described in [4].
