Packet Forwarding Technologies

Packet Forwarding Technologies

As Internet traffic continues to grow exponentially there is a great need to build Internet protocol (IP) routers with high-speed and high-capacity packet networking capabilities. The first book to explore this subject Packet Forwarding Technologies explains in depth packet forwarding concepts and implementation technologies. It covers the data structures algorithms and architectures used to implement high-speed routers. Following an introduction to the architecture of IP routers the author discusses how IP address lookup is one of the major bottlenecks in high-performance routers. He describes the characteristics of a routing table and addresses the difficulty of the longest-matching prefix search. The remainder of the book deals with fast IP address lookup. Coverage includes the various available architectures data structures and algorithms based on software and hardware as well as detailed discussions on state-of-the-art innovations. With many illustrations tables and simulations this practical guide to packet forwarding technologies facilitates understanding of IP routers and the latest router designs.

Making Your Data Center Energy Efficient

Making Your Data Center Energy Efficient

Detailing powerful methods for reducing the energy costs associated with operating a data center Making Your Data Center Energy Efficient examines both equipment and building facilities. It reviews the rationale for conserving energy and demonstrates how conservation and careful equipment selection can lead to significant improvements to your bottom line. For those not well-versed in financial or energy terms the first two chapters provide a detailed discussion of the terms associated with different types of energy as well as how to compute the return on investment for energy conservation efforts. The text includes tables of monthly expenses associated with operating equipment that will help you convert problems into simple table lookup processes. Among the money-saving topics discussed it considers: How to minimize the energy consumption of a wide range of devices A little-understood topic that can make a big impact on energy costs general heating and cooling Techniques required to effectively monitor different types of meters Phantom energy usage and methods for minimizing its cost to your organization Recognizing that most readers may not have direct control over the selection of a furnace or hot water heater the book provides you with the ability to recognize the efficiencies and inefficiencies of various types of devices so you can provide input into the decision-making process. From replacing lighting to consolidation and virtualization it provides you with the well-rounded understanding needed to properly manage all aspects of the energy consumed in your data center.

Business Analysis Requirements and Project Management A Guide for Computing Students

Business Analysis Requirements and Project Management A Guide for Computing Students

IT projects emerge from a business need. In practice software developers must accomplish two big things before an IT project can begin: find out what you need to do (i. e. analyse business requirements) and plan out how to do it (i. e. project management). The biggest problem in IT projects is delivering the wrong product because IT people do not understand what business people require. This practical textbook teaches computer science students how to manage and deliver IT projects by linking business and IT requirements with project management in an incremental and straightforward approach. Business Analysis Requirements and Project Management: A Guide for Computing Students presents an approach to analysis management that scales the business perspective. It takes a business process view of a business proposal as a model and explains how to structure a technical problem into a recognisable pattern with problem frames. It shows how to identify core transactions and model them as use cases to create a requirements table useful to designers and coders. Linked to the analysis are three management tools: the product breakdown structure (PBS) the Gantt chart and the Kanban board. The PBS is derived in part from the problem frame. The Gantt chart emerges from the PBS and ensures the key requirements are addressed by reference to use cases. The Kanban board is especially useful in Task Driven Development which the text covers. This textbook consists of two interleaving parts and features a single case study. Part one addresses the business and requirements perspective. The second integrates core project management approaches and explains how both requirements and management are connected. The remainder of the book is appendices the first of which provides solutions to the exercises presented in each chapter. The second appendix puts together much of the documentation for the case study into one place. The case study presents a real-word business scenario to expose students to professional practice. | Business Analysis Requirements and Project Management A Guide for Computing Students
