Abstract: We introduce a novel concept of multiple metric network tomography in this paper. The conventional network tomography observes a single parameter directly and infers another parameter indirectly from the the directly measured parameter. We consider observing two parameters (packet loss rate (PLR) and path delays) directly and use both of these parameters to infer a single parameter indirectly. We applied a variation of NTF1 model of non negative tensor factorization (NTF) for this purpose and estimated link delay. Simulation results should show a better correlation between the estimated and measured link delays when duplex of metrics is used as compared to using only the path level link delays for estimating the link delays on a test bed.
