The TCP/IP protocol suite has become the de facto standard for computer communications in today's networked world. The ubiquitous implementation of a specific networking standard has led to an incredible dependence on the applications enabled by it. Today, we use the TCP/IP protocols and the Internet not only for entertainment and information, but to conduct our business by performing transactions, buying and selling products, and delivering services to customers.
Guy Davies has worked as an IP Architect for Telindus, a network integrator in the
UK, for four years. While at Telindus, he has been involved in many projects ranging

Modern WAN architectures require additional network capabilities to support current higher bandwidth
and mission-critical applications. Requirements for deploying voice over IP (VoIP) and video
conferencing include high availability, IP multicast, and quality of service (QoS). Today, most
enterprises rely on private WAN connections such as Frame Relay, ATM, or leased-line services to
connect their businesses.

Two technologies that have profoundly impacted people on this planet recently are
cellular telephony and the Internet. The former, with its tremendous advantages of
tetherless and ubiquitous communication capabilities, was accepted worldwide. It
met the expectations of a success story for wealthy nations. On the other hand, its
reach into the developing and the not-so-prosperous parts of the world was even

Module 3: Configuring and managing WINS. This module explains how to configure, manage, and troubleshoot Microsoft Windows Internet Name Service (WINS) servers. WINS is a NetBIOS Name Server (NBNS) that you can use to resolve NetBIOS names to IP addresses. The main contents in module includes: Installing the windows internet name service, managing the WINS server, configuring WINS replication, migrating from WINS to DNS.
Module 5: Configuring and troubleshooting IPv6 TCP/IP. This module introduces you to IPv6, a technology that will help ensure that the Internet can support a growing user base and the increasingly large number of IP-enabled devices. The current Internet Protocol Version 4 (IPv4) has served as the underlying Internet protocol for almost thirty years. Its robustness, scalability, and limited feature set is now challenged by the growing need for new IP addresses, due in large part to the rapid growth of new network-aware devices.
Module 9: Configuring IPsec. Internet Protocol security (IPsec) is a framework of open standards for protecting communications over IP networks through cryptographic security services. IPsec supports network-level peer authentication, data-origin authentication, data integrity, data confidentiality (encryption), and replay protection. The Microsoft IPsec implementation is based on standards that the Internet Engineering Task Force (IETF) IPsec working group developed. In this module, you will learn how to implement, configure, and troubleshoot IPsec.
This book provides a complete guide to the SSL VPN technology and discusses its implementation on
Cisco SSL VPN–capable devices. Design guidance is provided to assist you in implementing SSL VPNs
in an existing network infrastructure. This includes examining existing hardware and software to determine
whether they are SSL VPN capable, providing design recommendations, and guiding you on setting
up the Cisco SSL VPN devices.
Toward the end of Chapters 5 and 6, common deployment scenarios are covered to assist you in deploying
an SSL VPN in your network...
The data center is the repository for applications and data critical to the modern enterprise. The
enterprise demands on the data center are increasing, requiring the capacity and flexibility to address a
fluid business environment whilst reducing operational costs. Data center expenses such as power,
cooling, and space have become more of a concern as the data center grows to address business
Blade servers are the latest server platforms that attempt to address these business drivers.
There was a time when each of your employees had no more than a
computer. The user-to-device ratio was one-to-one. But look around
you today. What do you see? Wireless devices, IP telephones, IP security
cameras, IP building controls, and more—all converged on the same
network. The number of applications supported by a single network
has grown tenfold. According to premier research provider IDC, nearly
three-quarters of global organizations are expected to migrate to a fully
converged enterprise by the end of 2008.+...
