The TCP/IP protocol suite represents an important technology in today's enterprise networking environment. Describing the protocols that make up the TCP/IP suite, this book provides readers with the background to choose TCP/IP internet hardware and software products to best satisfy their specific requirements. Leading computer authority James Martin and co-author Joe Leben present an overall framework that enables readers to install and maintain specific TCP/IP products. Part I introduces the TCP/IP networking environment and describes the overall architecture of the TCP/IP protocol suite. Part II describes the TCP/IP protocols and services that are employed by end users for doing useful work. Part III examines the two major TCP/IP transport protocols: User Datagram Protocol (UDP) and Transmission Control Protocol (TCP). Part IV investigates the low-level protocols in the TCP/IP protocol suite that are used to provide basic packet delivery facilities. Part V concentrates on network management, administration, and troubleshooting procedures to keep a TCP/IP internet running. Part VI presents the programming techniques that are used in writing application programs that communicate over a TCP/IP internet.
