From this page here (check out the menu at the top of the page), you can find resources and information of interest to students, teachers, and readers alike.

Since the publication of the first edition 20 years ago, the book has been adopted at many hundreds of colleges and universities, translated into 14 languages, and used by literally millions students and practitioners worldwide. We’ve been overwhelmed by the positive response.

This textbook is for a first course on computer networking. It has been used in computer science and electrical engineering departments, information systems and informatics departments, in business schools, and elsewhere - at both the undergraduate and graduate levels. It should also be of interest to practitioners in industry as well. Find out more about the textbook here.
