Installing the shaper in ns is a quite easy operation. Just follow the instructions below: 1. Copy the files dsshaper.h and dsshper.cc to the ns directory 2. Include dsshaper.o into the Makefile (see the Marc Greis tutorial, if you don't know where is the correct place) 3. Execute configure and make If you have problems with the installation you can send me an email: cak@cin.ufpe.br Comments will be wellcome! GOOK LUCK ! PS: The shaper is for ns2.1b5
