The TCP/IP family of protocols have become the de facto standard in the world of networking, are found in virtually all computer communication systems, and form the basis of today's Internet. TCP/IP Essentials is a hands-on guide to TCP/IP technologies, and shows how the protocols are implemented in practice. The book contains a series of extensively tested laboratory experiments that span the various elements of protocol definition and behavior. Topics covered include bridges, routers, LANs, static and dynamic routing, multicast and realtime service, and network management and security. The experiments are described in a Linux environment, with parallel notes on Solaris implementation. The book includes many homework exercises, and supplementary material for instructors is available. The book is aimed at students of electrical and computer engineering and students of computer science taking courses in networking. It is also an ideal guide for engineers studying for networking certifications.

Pv6 Essentials discusses all aspects of IPv6, the protocol that will be used increasingly in our IP-based networks. IPv4, probably the most important networking standard in use, is growing old. It was developed almost 30 years ago and isn't able to cope with the requirements of tomorrow's networks. IPv6 is the evolution of IPv4. The two protocols are expected to coexist in our networks for many years to come. Many interoperability and transition mechanisms have been developed to ensure a smooth transition. Topics covered in this book include : The IPv6 header, Extension headers, and everything you need to know about the extended 128-bit address format ; ICMPv6 and its functions, such as neighbor and router discovery, autoconfiguration, Path MTU discovery, and multicast group management ; Security elements available in IPv6 and the IPSEC framework ; Description of QoS elements available in IPv6, including different QoS architectures ; Designs of sample networks and an overview of Mobile IPv6 ; Routing protocols such as RIPng, OSPFv3, BGP, and IS-IS. DHCP, DNS, SLP, HTTP, and other upper-layer protocols for IPv6. Interoperability and transition mechanisms and scenarios. Quick-start guide to using IPv6 on different operating systems, such as Sun Solaris, Linux, and Windows, and on routers IPv6 Essentials offers a well-organized introduction to IPv6 for experienced network professionals, as well as for administrators, managers, and executives. It explains the new features and functions of IPv6 and shows the protocol in action, including packet trace files. The book also provides an overview of where the market is, how to register IPv6 address space, and how to get started. Even if you don't plan to roll out IPv6 tomorrow, this book will help you to determine the right moment to integrate it into your corporate network strategy.

This book is designed to acquaint the readers with major aspects of e-commerce with particular emphasis on technology such as cryptography, e-payment and mobile payment security. The book presents a layered architecture of e-commerce systems with six layers. The physical layer (the bottommost layer) described first, provides the basic communication infrastructure needed by e commerce. The next layer described is the logical layer consisting of Local Area Networks, the Internet, Intranet, etc. which provide connectivity. The layer above is the network services layer which provides e-mail and World Wide Web applications. Above this is a very important messaging layer of e-commerce which provides facilities for exchanging messages securely using the communication infrastructure. Here various methods of encryption, public key infrastructure and digital signature are discussed. It is also explained as to how the messaging layer is used to exchange structured electronic documents, using XML. The next layer called middleman services layer, describes the design of home page of an organization and elaborates various payment services such as credit card, e cash, smart card, etc. The topmost layer is on applications, namely, B2C, B2B and C2C e commerce which are defined and described at the beginning of the book. As use of mobile phones and mobile network is rapidly increasing, a whole chapter is devoted to explain m-commerce. Of special interest are detailed discussions of Wireless Application Protocol, security issues and payment methods. A complete chapter is also devoted to new developments in multimedia information goods such as e-books, MP3 compressed audio and digital quality video. A unique feature of these goods is the method of delivery which also uses the mobile Internet infrastructure. Finally, the legal framework of e-commerce provided by the Information Technology Act 2000 (and the amended act of 2008) is explained. This book with its numerous student-friendly features is an ideal text for undergraduate and postgraduate students of Computer Science and Information Technology (BSc and MSc), Computer Applications (BCA and MCA), and for undergraduate engineering students of Computer Science and Engineering and Information Technology. Besides, it would be useful to professionals for quickly understanding the basics of e commerce. Key Features : • Gives detailed discussions of security and payment schemes in e-commerce. • Discusses essentials of m-commerce technology including WAP protocol and mobile security. • Discusses e-commerce of multimedia such as e-books, MP3 audio and video on demand. • Provides learning aids such as chapter summaries, over 300 review questions and 350 objective type questions.
