Practical Network Design Techniques: A Complete Guide For WANs and LANs, Second Edition

The authors of Practical Network Design Techniques, Second Edition: A Complete Guide for WANs and LANs build upon the popular first edition by combining pre-existing network design fundamentals with new material on LAN devices and topologies, wireless local networks, and LAN internetworking issues. This new edition has two parts. The first part focuses on wide area networks; the second, which is entirely new, focuses on local area networks. Because Ethernet emerged victorious in the LAN war, the second section pays particular attention to Ethernet design and performance characteristics. The volume retains much valuable information from the first edition, and integrates and prominently highlights WAN information that is also relevant to the LAN design process. To maximize the book's utility, the authors include a number of practical networking problems and their solutions, along with examples of methods needed to perform economic comparisons among differing communications services and hardware configurations. The second edition provides a thorough understanding of major network design problems and is an invaluable reference for data communications professionals. Booknews On the major types of network design problems. Uses basic and advanced mathematics to cover key problems such as location of multiplexers, number and configuration of multiplexer and concentrator ports for specific terminal populations, means of routing multidrop lines to optimize their costs, types of line facilities for use under different networking conditions. Includes a selection of practical networking problems and solutions. Major listed programs are offered on a PC disk (at $115). Annotation c.

Taking an inclusive approach, the author examines the cost and performance issues that can also be used by network analysts and designers as tools and techniques to optimize existing networks with respect to their cost or performance. He examines reports generated by communications equipment to obtain an understanding of how different report elements can be used to tailor the cost or performance of a network segment IntroductionRationaleBook OverviewWIDE AREA NETWORK DESIGN TECHNIQUESTransmission CharacteristicsCommunications ConstraintsInformation Transfer RateBISYNC Communications Protocol ModelsWide Area Network Line Facilities and Economic TradeoffsLine ConnectionsLeased versus Switched Facility AnalysisAdditional Analog Facilities to ConsiderDigital FacilitiesMultiplexing, Routing, and Line Sharing EquipmentMultiplexers and Data ConcentratorsRoutersModem- and Line-Sharing UnitsLocating Data Concentration EquipmentGraph Theory and Network DesignEquipment Location TechniquesMultidrop Line Routing Techn 4.1.8.2 Hub-Bypass Multiplexing4.1.8.3 Front-End Substitution; 4.1.8.4 Inverse Multiplexing; 4.1.9 Multiplexing Economics; 4.1.10 Statistical and Intelligent Multiplexers; 4.1.10.1 Statistical Frame Construction; 4.1.10.2 Buffer Control; 4.1.10.3 Service Ratio; 4.1.10.4 Data Source Support; 4.1.10.5 Switching and Port Contention; 4.1.10.6 Intelligent Time Division Multiplexes; 4.1.10.7 STDM/ITDM Statistics; 4.1.10.8 Using System Reports; 4.1.10.9 Features to Consider; 4.2 Routers; 4.2.1 Functionality; 4.2.2 Ports and Connectors; 4.2.3 Address Resolution; 4.2.4 Hardware and Software Front cover; Contents; Preface; Acknowledgments; 1; Introduction; 1.1 Rationale; 1.2 Book Overview; 1.2.1 WAN Design; 1.2.2 LAN Design; Section I; Wide Area Network Design Techniques; 2; Transmission Characteristics; 2.1 Communications Constraints; 2.1.1 Throughput; 2.1.2 Response Time; 2.2 Information Transfer Rate; 2.2.1 Delay Time; 2.2.2 Other Delay Factors; 2.3 BISYNC Communications Protocol Models; 2.3.1 Error Control; 2.3.2 Half-Duplex Throughput Model; 2.3.2.1 Computation Examples; 2.3.2.2 Block Size versus Error Rate; 2.3.3 Return Channel Model; 2.3.4 Full-Duplex Model; 3 Wide Area Network Line Facilities and Economic Trade-Offs3.1 Line Connections; 3.1.1 Dedicated Line; 3.1.2 Leased Line; 3.1.3 Switched Line; 3.2 Leased versus Switched Facility Analysis; 3.2.1 Servicing Additional Terminal Devices; 3.2.2 Line Sharing Economics; 3.2.3 Concepts to Consider; 3.3 Additional Analog Facilities to Consider; 3.3.1 WATS; 3.3.2 Foreign Exchange; 3.3.2.1 Economics of Use; 3.4 Digital Facilities; 3.4.1 AT & T Offerings; 3.4.2 European Offerings; 3.4.2.1 Data Service Units; 3.4.3 Economics of Use; 3.4.4 Dataphone Digital Service; 3.4.5 Accunet T1.5 3.4.5.1 DDS as Opposed to Accunet T1.53.4.6 Accunet Spectrum of Digital Services; 3.4.6.1 Comparison to Other Digital Services; 3.4.6.2 Accunet T45; 4; Multiplexing, Routing, and Line Sharing Equipment; 4.1 Multiplexers and Data Concentrators; 4.1.1 Evolution; 4.1.2 Comparison with Other Devices; 4.1.3.
