Ensure that your WAN can handle the latest technologies with this must-have strategy guide
If a Wide Area Network (WAN) isn't set up properly, it won't be able to meet the needs of the applications being used in the Local Area Network (LAN). And with the emergence of new technologies such as VPNs, multi-service networks, and the mobility of corporate users, the costs involved with running a WAN have changed dramatically. Written by an expert on WAN design, this book provides a comprehensive strategy for choosing the best technologies available for your WAN. It includes analysis of business requirements for WANs, end-user and service provider requirements, and the capabilities and tradeoffs of the available technologies. The book also covers the realities and limitations of QoS, security, multi-service networks, virtual networks, VPNs, multi-homing, roaming, and mobility.
Learn to choose the best technologies for your WAN while keeping costs under control From VPNs to multiservice networks that carry voice, video, and data, to mobility for corporate users––new technologies are rapidly changing the way we manage and design wide area networks. And with WAN costs accounting for 75-90 percent of the lifecycle costs for most enterprise networks, it is becoming increasingly critical to understand the economies of running a WAN. This book provides you with a complete strategy for integrating the latest technologies into your WAN and ensuring availability and quality of service while balancing costs.
Whether you plan to add new capabilities to your network or modify existing ones, expert WAN designer Howard Berkowitz walks you step-by-step through all existing WAN services plus their matching business requirements and cost analysis. Along the way, he debunks myths about what’s practical on a WAN, discusses capabilities and tradeoffs of widely used technologies, and reveals the realities and limitations of different services.
With WAN Survival Guide at your side, you’ll be able to:
- Formulate end-user and service provider requirements
- Avoid costs through multiservice networking and reduced downtime
- Set up, manage, and enforce QoS
- Provide basic services through dedicated lines, frame relay, ATM, and similar technologies
- Take advantage of virtual networks, VPNs, security, roaming, and mobility
- Work with database fault tolerance and multihoming
Networking Council Books put technology into perspective for decision-makers who need an implementation strategy, a vendor and outsourcing strategy, and a product and design strategy.
