Networking books come in two basic flavors: Platform-neutral and vendor-specific. Nortel Networks: The Complete Reference takes mainly the latter approach, explaining how data moves across (and among) networks based on Nortel equipment, including those products Nortel acquired when it bought Bay Networks. There''s rather a lot of theory and quite a number of universal truths mixed in with the Nortel information. For that reason, and because author James Knapp''s presentation style is so strong, you''re likely to derive value from this work even if you use other companies'' hardware and software. Knapp''s coverage runs the gamut from local Ethernet to Layer 3 switching, Asynchronous Transfer Mode (ATM), and internetworking, so there''s something here for network engineers in organizations large and small. Knapp''s approach is unfailingly practical, always considering real-life situations and the best way to derive maximum performance from real networks. To this end, he''s included numerous anecdotes from his time spent as a Nortel engineer, and he''s provided conceptual background with excellent diagrams in many cases. You''ll particularly love this book if you own one of the Nortel products--listed below--that Knapp thoroughly investigates. For each covered product, you get a highly detailed look at its capabilities, appropriate use, and management specifics--all in an easy-to-follow style. For a shop that uses Nortel network equipment, this book should be required documentation. --David Wall Topics covered: Theory of Ethernet and the Open Systems Interconnect (OSI) reference model, Ethernet implementations (with emphasis on BayStack, Centillion, and LattisSpan equipment), Layer 3 switching with Accelar gear, Asynchronous Transfer Mode (ATM) concepts (including Quality of Service and Private Network-to-Network Interfaces), ATM as implemented under the Centillion series, and internetwork routing with Nortel routers.

ASP.NET permite a los sitios web mostrar páginas únicas a cada visitante en lugar de las mismas páginas HTML estáticas. La versión ASP.NET 2.0 es un avance en el área del desarrollo de aplicaciones Web con la que se pueden realizar operaciones de creacion y administracion de usuarios mucho mas sencillas, asi como proteger las paginas de una aplicacion Web por medio de contraseñas. El nuevo marco incorpora caracteristicas novedosas para el trabajo con la autenticacion y la autorizacion que se han diseñado para que resulten igualmente atractivas para administradores de sitios Web y desarrolladores.Este libro le muestra todas las nuevas opciones y utilidades que proporciona ASP.NET 2.0 para prepararse para utilizar las nuevas tecnologias integradas; no solo presenta nuevos temas sino que, ademas, analiza ejemplos de dichas tecnologias en accion. Con mas de 50 nuevos controles de servidor, se ha duplicado la cantidad de clases y, en muchos casos, los cambios en esta nueva version son impresionantes.Con esta obra aprendera a crear paginas ASP.NET con plantillas utilizando la nueva opcion de pagina principal, utilizar tecnicas para depurar y controlar errores, metodos para empaquetar y desplegar aplicaciones ASP.NET o como recuperar, actualizar y eliminar datos rapida y logicamente, entre otras muchas aplicaciones.

The first volume of Unix Network Programming, Networking APIs: Sockets and XTI covers just about everything you need to know to get your applications to talk to other computers on a network. In this second volume, W. Richard Stevens discusses what you need to know to get your applications to talk to other applications running on your computer. There's a big difference, and Stevens covers it well. Stevens introduces the reader to the internal structures of Posix interprocess communication (IPC) and System V (SysV) IPC; pipes and first in, first outs (FIFOs); message queues; how to lock and unlock files and records; semaphores; shared memory; and remote procedure calls (RPCs). He explains the difference between the Posix and SysV implementations of semaphores, message queues, and shared memory. There are also plenty of notes and examples for the reader. This book is invaluable for programmers because it explains all of those little "gotchas" that always seem to pop up. In addition, the explanations of the differences between Posix IPC and SysV IPC really help readers decide which version they'd like to use for their applications. --Doug Beaver

For junior to graduate-level courses in Computer Networks, Data Networks, Network Protocols, and Internetworking. This best-selling, conceptual introduction to TCP/IP internetworking protocols interweaves a clear discussion of fundamentals with the latest technologies. Leading author Doug Comer covers layering and shows how all protocols in the TCP/IP suite fit into the five-layer model. With a new focus on CIDR addressing, this revision addresses MPLS and IP switching technology, traffic scheduling, VOIP, Explicit Congestion Notification (ECN), and Selective ACKnowledgement (SACK).

The Internet of Things (IoT) is the notion that nearly everything we use, from gym shorts to streetlights, will soon be connected to the Internet; the Internet of Everything (IoE) encompasses not just objects, but the social connections, data, and processes that the IoT makes possible. Industry and financial analysts have predicted that the number of Internet-enabled devices will increase from 11 billion to upwards of 75 billion by 2020. Regardless of the number, the
