Welcome to our online textbook, Computer Networking: A Top-Down Approach. We ( Jim Kurose, Keith Ross, and Addison-Wesley-Longman) think you will find this textbook to be very different than the other computer networking books that are currently available. Perhaps the most unique and innovative feature of this textbook is that it is online and accessible through a Web browser. We believe that our online format has several things going for it.
