A new era of network services has evolved to meet the needs of IP-centric networking requirements and customer opportunity. The emphasis is on service as IP has become a prolific communications portal through which to deliver interactive solutions that improve business execution, tie the individual consumer into commerce, and extend market reach by removing the last barriers of time and distance.
Next-Generation Network Services presents an overview of converged IP network services, focusing on opportunities for service differentiation and introducing current service-oriented technology. These technologies allow service providers and large enterprises to build and operate networks that provide local, long-haul, mobile, and global data and Internet services to businesses and consumers.
This book explores the service provider opportunity in the new era, discussing what has changed and why a service-centric focus is the new ascendancy. This book introduces an extensive portfolio of network technologies and explains the market advantages and the service value of each solution, including IP, multiservice, virtual private network (VPN), optical, wireline, and wireless networks.
Whether you are a network architect or engineer driving service innovation within a service provider or enterprise network, or you are a network executive or technology analyst looking to gain a broad overview of the telecommunications sector, Next-Generation Network Services offers you insight into the evolving internetworking technologies that will shape the future of network growth.

Network Administrators Survival Guide solves many common network administration problems by providing administrators with an all-in-one practical guide to supporting Cisco networks using freeware tools. It provides the explanation of particular issues, its significance for the administrator, and the installation and configuration process for the tool. The solutions are Cisco-centric and more detailed and accurate than generic information available online. Each chapter is broadly based on a network administration function. It starts with an overview of the topic, followed by the methodology involved to accomplish that function. This includes the tools available, why they are the right choices, and their installation, configuration, and usage methods. For any given function, this book covers both Windows- and Linux-based tools, as appropriate. This will benefit a wider reader base, as both operating systems are used in the networking community. Most of the Windows-based tools offer the advantage of GUI for ease of use. On the other hand, Linux-based tools are command-line based and can be used in automated scripts. Both are significant for network administrators. At the end of every chapter is a list that covers the name, function, operating system, and website details of all the tools discussed.

Use Cisco concentrators, routers, Cisco PIX and Cisco ASA security appliances, and remote access clients to build a complete VPN solution
A complete resource for understanding VPN components and VPN design issues
Learn how to employ state-of-the-art VPN connection types and implement complex VPN configurations on Cisco devices, including routers, Cisco PIX and Cisco ASA security appliances, concentrators, and remote access clients
Discover troubleshooting tips and techniques from real-world scenarios based on the author’s vast field experience
Filled with relevant configurations you can use immediately in your own network
With increased use of Internet connectivity and less reliance on private WAN networks, virtual private networks (VPNs) provide a much-needed secure method of transferring critical information. As Cisco Systems® integrates security and access features into routers, firewalls, clients, and concentrators, its solutions become ever more accessible to companies with networks of all sizes. The Complete Cisco VPN Configuration Guide contains detailed explanations of all Cisco® VPN products, describing how to set up IPsec and Secure Sockets Layer (SSL) connections on any type of Cisco device, including concentrators, clients, routers, or Cisco PIX® and Cisco ASA security appliances. With copious configuration examples and troubleshooting scenarios, it offers clear information on VPN implementation designs.
Part I, “VPNs,” introduces the topic of VPNs and discusses today’s main technologies, including IPsec. It also spends an entire chapter on SSL VPNs, the newest VPN technology and one that Cisco has placed particular emphasis on since 2003. Part II, “Concentrators,” provides detail on today’s concentrator products and covers site-to-site and remote-access connection types with attention on IPsec and WebVPN. Part III covers the Cisco VPN Client versions 3.x and 4.x along with the Cisco3002 Hardware Client. Cisco IOS® routers are the topic of Part IV, covering scalable VPNs with Dynamic Multipoint VPN, router certificate authorities, and router remote access solutions. Part V explains Cisco PIX and Cisco ASA security appliances and their roles in VPN connectivity, including remote access and site-to-site connections. In Part VI, a case study shows how a VPN solution is best implemented in the real world using a variety of Cisco VPN products in a sample network.
