"Sets out the design and management principles of large-scale IP networks by weaving together theory and practice."--Electronic Library.

An essential guide to scaling and maintaining large networks.Understand critical scalability issues and the parameters to plan for future network growth Examine detailed migration plans with sample scenarios and working Cisco configuration examples Learn the pros and cons of each major routing protocol and how to choose the right one for your environment Understand the operations and scalability features of Protocol Independent Multicast (PIM) Implement effective quality of service and network management techniques Benefit from extensive large-scale network design and configuration case studiesLarge-Scale IP Network Solutions provides practical advice for network engineers as IP networks grow and become more complex. With in-depth discussions of the major IP protocols--including RIP, Enhanced IGRP, OSPF, IS-IS, and BGP--this book evaluates the strengths and weaknesses of each protocol. In addition to specific large and medium network protocol deployment issues, this guide contains special sections on more general topics such as network management, core and distribution networks, multicasting, and quality of service features.Router configuration examples, network case studies, and sample scenarios all help you put the book's information to use and become an effective Cisco Certified Internetwork Expert (CCIE). In addition, this title offers unique elements to help you prepare for the exam, including: case studies that highlight real-world design, implementation, management, and troubleshooting issues; configuiration examples from actual network input and output; scenarios that help you put solutions to use; and review questions and exercises.

An oft-repeated adage among telecommunication providers goes, “There are ve things that matter: reliability, reliability, reliability, time to market, and cost. If you can’t do all ve, at least do the rst three. ” Yet, designing and operating reliable networks and services is a Herculean task. Building truly reliable components is unacceptably expensive, forcing us to c- struct reliable systems out of unreliable components. The resulting systems are inherently complex, consisting of many different kinds of components running a variety of different protocols that interact in subtle ways. Inter-networkssuch as the Internet span multiple regions of administrative control, from campus and cor- rate networks to Internet Service Providers, making good end-to-end performance a shared responsibility borne by sometimes uncooperative parties. Moreover, these networks consist not only of routers, but also lower-layer devices such as optical switches and higher-layer components such as rewalls and proxies. And, these components are highly con gurable, leaving ample room for operator error and buggy software. As if that were not dif cult enough, end users understandably care about the performance of their higher-level applications, which has a complicated relationship with the behavior of the underlying network. Despite these challenges, researchers and practitioners alike have made trem- dous strides in improving the reliability of modern networks and services.

This book covers the design and optimization of computer networks applying a rigorous optimization methodology, applicable to any network technology. It is organized into two parts. In Part 1 the reader will learn how to model network problems appearing in computer networks as optimization programs, and use optimization theory to give insights on them. Four problem types are addressed systematically – traffic routing, capacity dimensioning, congestion control and topology design. Part 2 targets the design of algorithms that solve network problems like the ones modeled in Part 1. Two main approaches are addressed – gradient-like algorithms inspiring distributed network protocols that dynamically adapt to the network, or cross-layer schemes that coordinate the cooperation among protocols; and those focusing on the design of heuristic algorithms for long term static network design and planning problems. Following a hands-on approach, the reader will have access to a large set of examples in real-life technologies like IP, wireless and optical networks. Implementations of models and algorithms will be available in the open-source Net2Plan tool from which the user will be able to see how the lessons learned take real form in algorithms, and reuse or execute them to obtain numerical solutions. An accompanying link to the author’s own Net2plan software enables readers to produce numerical solutions to a multitude of real-life problems in computer networks (www.net2plan.com).

This book covers diverse aspects of advanced computer and communication engineering, focusing specifically on industrial and manufacturing theory and applications of electronics, communications, computing and information technology. Experts in research, industry, and academia present the latest developments in technology, describe applications involving cutting-edge communication and computer systems, and explore likely future trends. In addition, a wealth of new algorithms that assist in solving computer and communication engineering problems are presented. The book is based on presentations given at ICOCOE 2015, the 2nd International Conference on Communication and Computer Engineering. It will appeal to a wide range of professionals in the field, including telecommunication engineers, computer engineers and scientists, researchers, academics and students.

Technical specialists and network managers explain how to design, build, and operate a large global Internet Protocol network, and overview many of the transport and access components. After discussing carrier-scale networks and IP networks in general, they look at scaling issues, peering with other networks, and other practical building and maintaining issues; the connections between the points of presence of an Internet provider and their customers; and some less technical aspects of operations. Issues of network management are discussed throughout as appropriate. Annotation copyrighted by Book News, Inc., Portland, OR
