Network Design outlines the fundamental principles and analytical techniques used in designing data networks. The text enables future managers and technical professionals to better understand and appreciate each other's perspective in the network design process. Network managers will need a sound grounding in basic design principles to effectively manage, plan, and assess the plethora of new technologies and equipment available for designing networks. They also must understand how requirements should be formulated and specified for design engineers. Similarly, network designers and engineers need a sound grounding in basic management principles to fully understand how organizational requirements best reflect design recommendations. Network Design enables network management and design professionals to work together toward achieving their respective goals in the network design process. It outlines basic techniques; reviews major challenges and issues; summarizes prevailing approaches and technologies; describes the specification, design, and planning data network topologies; and assesses specification and evaluation processes in designing and implementing data networks. This excellent, unique resource also : Emphasizes principles and analytical approaches that work independent of specific implementation of technology Includes case studies to illustrate how basic principles can be applied to realistic network design problems, considering both technical and management considerations Demystifies the design process, describing the lingua franca of both managers and design engineers in common terms Provides a better understanding of the total network design process

This edited book serves as a companion volume to the Seventh INFORMS Telecommunications Conference held in Boca Raton, Florida, March 7-10, 2004. The 18 papers in this book were carefully selected after a thorough re view process. The research presented within these articles focuses on the latest methodological developments in three key areas—pricing of telecommunica tions services, network design, and resource allocation—that are most relevant to current telecommunications planning. With the global deregulation of the telecommunications industry, effective pricing and revenue management, as well as an understanding of competi tive pressures are key factors that will improve revenue in telecommunica tions companies. Chapters 1-5 address these topics by focusing on pricing of telecommunications services. They present some novel ideas related to pricing (including auction-based pricing of network bandwidth) and modeling compe tition in the industry. The successful telecommunications companies of the future will likely be the ones that can minimize their costs while meeting customer expectations. In this context the optimal design/provisioning of telecommunication networks plays an important role. Chapters 6-12 address these topics by focusing on net work design for a wide range of technologies including SONET, SDH, WDM, and MPLS. They include the latest research developments related to the mod eling and solving of network design problems. Day-to-day management/control of telecommunications networks is depen dent upon the optimal allocation of resources. Chapters 13-18 provide insight ful solutions to several intriguing resource allocation problems.

No previous knowledge of data communications and related fields is required for understanding this text. It begins with the basic components of telephone and computer networks and their interaction, centralized and distributive processing networks, Local Area Networks (LANs), Metropolitan Area Networks (MANs), Wide Area Networks (WANs), the International Standards Organization (OSI) Management Model, network devices that operate at different layers of the OSI model, and the IEEE 802 Standards. This text also introduces several protocols including X.25, TCP/IP, IPX/SPX, NetBEUI, AppleTalk, and DNA. The physical topologies, bus, star, ring, and mesh are discussed, and the ARCNet, Ethernet, Token Ring, and Fiber Distributed Data Interface (FDDI) are described in detail. Wiring types and network adapters are well covered, and a detailed discussion on wired and wireless transmissions including Bluetooth and Wi-Fi is included. An entire chapter is devoted to the various types of networks that one can select and use for his needs, the hardware and software required, and tasks such as security and safeguarding data from internal and external disasters that the network administrator must perform to maintain the network(s) he is responsible for. Two chapters serve as introductions to the Simple Network Management Protocol (SNMP) and Remote Monitoring (RMON). This text includes also five appendices with very useful information on how computers use numbers to condition and distribute data from source to destination, and a design example to find the optimum path for connecting distant facilities. Each chapter includes True-False, Multiple-Choice, and problems to test the reader's understanding. Answers are also provided.

There are hundreds of technologies and protocols used in telecommunications. They run the full gamut from application level to physical level. It is overwhelming to try to keep track of them. Network Design, Second Edition: Management and Technical Perspectives is a broad survey of the major technologies and networking protocols and how they interrelate, integrate, migrate, substitute, and segregate functionality. It presents fundamental issues that managers and engineers should be focused upon when designing a telecommunications strategy and selecting technologies, and bridges the communication gap that often exists between managers and technical staff involved in the design and implementation of networks. For managers, this book provides comprehensive technology overviews, case studies, and tools for decision making, requirements analysis, and technology evaluation. It provides guidelines, templates, checklists, and recommendations for technology selection and configuration, outsourcing, disaster recovery, business continuity, and security. The book cites free information so you can keep abreast of important developments. Engineers benefit from a review of the major technologies and protocols up and down the OSI protocol stack and how they relate to network design strategies. Topics include: Internet standards, protocols, and implementation; client server and distributed networking; value added networking services; disaster recovery and business continuity technologies; legacy IBM mainframe technologies and migration to TCP/IP; and MANs, WANs, and LANs. For engineers wanting to peek under the technology covers, Network Design provides insights into the mathematical underpinnings and theoretical basis for routing, network design, reliability, and performance analysis. This discussion covers star, tree, backbone, mesh, and access networks. The volume also analyzes the commercial tools and approaches used in network design, planning, and management.

Telecommunications will face a tremendous challenge in the coming years to be able to design, architect, and manage networks in such a rapidly evolving industry. Develop ment and application of heuristic methods will be fundamental to our ability to meet this challenge.

The choices are either to continue using the current architecture, or to make a large incremental investment in new equipment which reduces the number of high speed inter-office trunks required to interconnect the switches. The analysis requires optimizing the mix of two types of customer port cards to determine the maximum customer port capacity of a switch. Simple approximations are used to estimate the number of inter-office trunks and trunk cards required. Based in large part on the costs computed by this model, an executive level decision was made to move to the new architecture. Key Words: data communications, network architecture, network design, frame relay, virtual circuits, economic analysis 1. Introduction To design a data communications network, it is necessary to consider a variety of factors.

It is widely agreed that the future capabilities of the information industry will rely heavily upon successful, forward-looking network management strategies. This volume addresses recent research and practice in telecommunications management.
