Overview
This book introduces the TCP/IP_savvy reader to the design and implementation of Internet protocols useful for maintaining network connections while moving from place to place. It describes the technology that makes mobile networking possible; in particular, it focuses on Mobile IP, the Internet Engineering Task Force (IETF) Standard for mobile networking. Written by Charles E. Perkins, a leader in the mobile networking field, this book discusses:
- Mobile IP
- Route optimization
- IP version 6
- Use of Dynamic Host Configuration Protocol (DHCP)
- Encapsulation
After reading Mobile IP, a network engineer will be able to produce implementations of Mobile IP for mobile nodes, foreign agents, and home agents. As with any Internet protocol, mobile IP requires precise handling of packetized control data; all of the needed steps for that handling are detailed fully in this book. The necessary control mechanisms for processing advertisements (perhaps received over wireless media) are given first, followed by the main part of the Mobile IP protocol, which addresses how the mobile node registers its current IP attachment information with the support infrastructure on its home network. This book also details how Mobile IP specifies the handling of data packets destined for the mobile node.
In addition to the base protocol, this book also presents newly specified enhancements to Mobile IP, and details the protocol support needed for enabling mobile networks using IPv6, the new version of IP with 128-bit addresses. Interactions between Mobile IP and other protocols (such as DHCP) are described, enabling network engineers to get a complete understanding of the system effects of deploying Mobile IP in enterprise networks. Other current trends in protocol development relevant to Mobile IP are also described, such as ways to reduce registration traffic with the home network, and first steps towards integrating Mobile IP with enterprise security installations such as firewalls and border routers.

Technical introduction to the design and implementation of Internet protocols for mobile network computing. Overviews wireless technologies, IP routing, architectures, middleware components and the relationship of mobile networking and wireless communication. Discusses the three main concepts of the IETF Mobile IP basic protocol procedures; advertisement, registration and tunneling. Explains agent solicitation and discovery, examines router messaging and addressing, registration procedures and agent processing. Dissects datagram delivery methodologies, IP-in-IP and generic record encapsulation, data management issues and routing failures. Examines route optimization principles, message formats, keys, special tunnels, home and foreign agent operations. Covers miscellaneous topics such as firewall traversal, configuration and isolation of mobile nets, multicast extensions and Management Information Bases (MIBs. Very good focus on IP version 6, especially enhancements over IPv4, and the Dynamic Host Configuration Protocol (DHCP, emphasizing its relationship and use in Mobile IP networks. This publication is based on the IETF protocol specifications and relevant RFCs, notably 2002, 2003 and 2004. Author is associated with the Internet Engineering Task Force (IETF.
