• IPv6: The New Internet Protocol, by Christian Huitema, Prentice-Hall, 1996, ISBN 0-13-241936-X. • concerning HTTP we will refer to TCP/IP Illustrated, Volume 3: TCP for Transactions, HTTP, NNTP, and the UNIX Domain Protocols, Addison-Wesley, 1996, ISBN 0-201-63495-3. With regard to Mobile IP the following two books are useful as additional sources: • Mobile IP: Design Principles and Practices by Charles E. Perkins, Addison-Wesley, 1998, ISDN 0-201-63469-4. • Mobile IP: the Internet Unplugged by James D. Solomon, Prentice Hall, 1998, ISBN 0-13-856246-6. Internetworking Technologies Handbook by Kevin Downes (Editor), H. Kim Lew, Steve Spanier, Tim Stevenson (Online: http://www-fr.cisco.com/univercd/cc/td/doc/cisintwk/ito_doc/index.htm) We will refer to other books, articles, and RFCs as necessary. In addition, there will be compulsory written exercises. Maguire Literature 1: 17 of 104 maguire@kth.se 2010.03.21 Internetworking/Internetteknik
