The ns Manual (formerly known as ns Notes and Documentation) is the main source of documentation. It is available in three formats:
This manual should be automatically updated daily (please send mail to ns-users if this automatic version is incorrect). In addition (because this automated process breaks sometimes, we have a manually updated copy as well in html, ps.gz, pdf).
Because ns is an evolving system, its documentation will never be completely up-to-date, but we do try to update it from time to time when new facilities are added to the simulator. Please check it out if you are in need of a reference.
