The same set of experiments run on the NSFNET have been repeated on NTTnet. In this

case the results are even sharper than those obtained with NSFNET: AntNet performance

For the UP, RP and UP-HS cases, dierences in throughput are not signicant (Figures AntNet keeps delays at low values, very close to those obtained by Daemon, while SPF,

In the UP and RP cases (Figures 13b and 14b) SPF and BF performs similarly, even if SPF

dierences between AntNet and each of its competitors are of one order of magnitude.

In the UP-HS case, again, SPF and BF show similar results, while Q-R performs compa-
