Ns and Nam with Comer's Computer Networks and Internets`

This web page describes how to use ns and nam as tools to help with the Comer textbook Computer Networks and Internets.

Currently this page maps chapters in the book to animations in the ns educational script repository. Eventually we hope to add pointers to laboratory assignments and other utilities.
