Designed for the beginner yet useful for the expert, COMPUTER NETWORKING FROM LANS TO WANS: HARDWARE, SOFTWARE, AND SECURITY covers all aspects of computer networking. Hardware details such as the operation of Ethernet, network media and devices, including hubs, switches, routers, and physical topology, are provided, with many design and troubleshooting examples. Software details such as the operation of the TCP/IP protocols, routing protocols, and network operating systems are examined. Applications, such as FTP, Telnet, and email are explained in detail, as are the requirements of writing client/server applications, with several working examples provided. Techniques for applying security to networking and computing activities are covered, including network management, secure communication methods such as SSH, TLS, and VPN, and the fundamentals of forensics.

Delivers the hard information the reader needs to assess network options for the 1990s. It describes how networks are configured, what your options are in the multivendor environment, and how you can get the most efficient and effective network solutions with limited communications budgets.

Written by today's leading experts in industry and academia, Wireless IP and Building the Mobile Internet is the first book to take a comprehensive look at the convergence of wireless and Internet technologies that are giving rise to the mobile wireless Internet. This cutting-edge resource provides you with an overview of all the elements required to understand and develop future IP based wireless multimedia communications and services. The book shows you how to integrate the latest technologies in mobility, wireless, and the Internet to achieve workable end-to-end solutions. You get detailed coverage of wireless IP and its relationship with other mobile technologies such as GPRS and UMTS. Moreover, this essential reference features discussions on wireless IP evolution; quality of service; resource management; TCP/IP in wireless IP networks; handoff, mobility and signaling; and services and applications. Essential reading for practicing mobile communications engineers, designers, and engineering managers, the book is also easily adoptable as a text for graduate-level courses.

"This course discusses the WAN technologies and network services required by converged applications in a complex network. The course allows you to understand the selection criteria of network devices and WAN technologies to meet network requirements. You will learn how to configure and troubleshoot network devices and resolve common issues with data link protocols. You will also develop the knowledge and skills needed to implement IPSec and virtual private network (VPN) operations in a complex network."--Back cover.
