Book Description

In recent years, socio-political trends toward environmental responsibility and the pressing need to reduce Run-the-Engine (RTE) costs have resulted in the concept of Green IT. Although a significant amount of energy is used to operate routing, switching, and transmission equipment, comparatively less attention has been paid to Green Networking. A clear and concise introduction to green networks and green network operations, Designing Green Networks and Network Operations: Saving Run-the-Engine Costs guides you through the techniques available to achieve efficiency goals for corporate and carrier networks, including deploying more efficient hardware, blade form-factor routers and switches, and pursuing consolidation, virtualization, and network and cloud computing.

The book:

  • Delineates techniques to minimize network power, cooling, floor space, and online storage while optimizing service performance, capacity, and availability
  • Discusses virtualization, network computing, and Web services as approaches for green data centers and networks
  • Emphasizes best practices and compliance with international standards for green operations
  • Extends the green data center techniques to the networking environment
  • Incorporates green principles in the intranet, extranet, and the entire IT infrastructures
  • Reviews networking, power management, HVAC and CRAC basics
  • Presents methodical steps toward a seamless migration to Green IT and Green Networking
