Platonov %J Computer Science %D 2009 %I arXiv %X In the paper the method for estimation of throughput metrics like available bandwidth and end-t-end capacity is supposed. This method is based on measurement of network delay $D_i$ for packets of different sizes $W_i$. The simple expression for available bandwidth $B_{av} =(W_2-W_1)/(D_2-D_1)$ is substantiated. The number of experiments on matching of the results received new and traditional methods is spent. The received results testify to possibility of application of new model. %U http://arxiv.org/abs/0907.3710v1
