Introduction to Communications Technologies is a quick-read tutorial on telecommunications
technologies for IT professionals and business managers. While dealing with the engineering aspects of communication,
the book provides a basic understanding of how things work, not how to design systems. Topics include systems,
electricity, signaling, telephony, switching, wireless, CTI, and video. It also explains the important relationship
between the two major languages spoken in the industry, voice and data, something not done in other texts. |
Building Broadband Networks clearly and thoroughly conveys the principles and the technical
fundamentals of the high-performance technologies that enable the reliable delivery of media-rich voice, video,
and data services. After a careful examination of ISDN and ATM technologies, it describes optical network solutions
based on SONET/SDH, WDM, and DWDM technologies. It then explores Ethernet, Frame Relay and Fibre Channel networks, DSL
solutions, and wireline and wireless cable networks; the capabilities of cellular technologies, describes the
characteristics of wireless networking technologies, and examines broadband satellite networks; and explores
next-generation network configurations, such as Internet2 and GEANT, and concludes with a study of network security
problems and solutions. |
The ABCs of IP Addressing provides a comprehensive reference to how
addressing is used in a TCP/IP environment. It assumes no prior knowledge. It includes
basic information, such as an overview of the binary numbering system as well as detailed
information concerning such topics as subnetting, network address translation, and similar
topics. It includes the configuration of workstations, servers, and routers. In addition,
it provides intermediate to advanced information concerning the development of subnets,
addressing schemes, the use of network address translation, and other topics. |
The ABCs of TCP/IP provides professionals with an overview of the TCP/IP suite and details its
key components. While many books on the subject focus on the details and minutae of TCP/IP, this book covers
applications, methods, concepts, and economics associated with the TCP/IP stack. It illustrates how to leverage
investments in TCP/IP and how to economize network operations. The ABCs of TCP/IP examines: the manner by which
various protocols and applications operate, addressing issues, security methods, routing, network design
constraints, testing methods, troubleshooting, management issues, and emerging applications. It also includes
separate chapters focusing on security threats and methods useful for overcoming these threats. |

A Technical Guide to IPSec Virtual Private Networks provides a technical explanation of a very complicated and misunderstood technology in terms that will allow the most novice of individuals to understand the inner workings of IPSec. It details the suite of IP Security protocols and their interaction with users, systems, and devices. It includes in-depth descriptions of the various IPSec communications and key management protocols that provide the foundation of secure communications. Includes multiple examples of implementations and real world experience and their comparison to the standards that make up IPSec.
Securing and Controlling Cisco Routers demonstrates proven techniques for strengthening network security. Beginning with an introduction to Cisco technology and the TCP/IP protocol suite, it then cover subjects such as routing, routing protocols, IP addressing, and Cisco Authentication, Authorization, and Accounting services (AAA). The text then addresses standard, extended, time-based, dynamic, and reflexive access lists, as well as context-based control and Cisco Encryption Technology.

SSL VPN for Secure Wireless LAN Access
When tasked with deploying a wireless LAN (WLAN) infrastructure within an organization, most people believe they must choose an outside vendor to implement a solution that is both scalable and secure, and does not expose the company's data to wireless users. However, if you have an SSL VPN appliance in place or are planning to implement one-perhaps to replace your IPsec VPN-you have all it takes to deploy a wireless LAN in-house. This article takes a look at the SSL VPN option, compares it to WLAN solutions, and covers the key benefits of an SSL VPN.

Rolling Out Municipal WiFi: The Trouble with Cities
This article concludes that an outdoors, public-space WiFi-only network cannot be made to work profitably in isolation,
except perhaps as a low-cost niche play (niche as in either geographical localisation or choice of vertical market). A
broader and more aggressive deployment strategy could make sense as an attempt to get a beach-head in an emerging
broadband wireless market where WiMAX will then do the heavy-lifting. But making a market entry with WiFi-WiMAX will
mean a head-on confrontation with mobile operators who have many advantages of incumbency. It will not be easy and will
take great tactical skill, as well as deep pockets.

Managing the Paradoxes of Mobile Technology
This article reports on a large-scale, international focus group study that examined the experiences
of mobile technology users in Hong Kong, Japan, Finland, and the United States. It identifies
eight central mobile technology paradoxes that shape user experience and behavior,
suggests possible design features that relate to the experienced paradoxes, and discusses
how these features could be better managed.

Introduction to Mobile Middleware
Traditional middleware solutions are not able to adequately manage these issues. Originally designed for use in a static context, such middleware systems hide low-level network details to provide a high level of transparency to applications. In mobile environments, though, the context is extremely dynamic and cannot be managed by a priori assumptions, so it is necessary to implement reconfiguration techniques that can react to changes in the operating context and develop powerful mechanisms to propagate such changes until the application level is reached. This chapter from
The Handbook of Mobile Middleware explains the new middleware for mobile systems that will provide mobility support.
