This network protocol reference handbook details the most common protocols currently in use by most networked sites. Using a one-chapter-per-protocol format, the book covers Transport Control Protocol/Internet Protocol (TCP/IP), Xerox Network System (XNS), Internet Packet Exchange/Sequence Packet Exchange (IPX/SPX), DECnet Phase IV/Local Area Transport (LAT), IEEE 802.2, and Open Systems Interconnection (OSI/GOSIP). Explaining how these protocols operate, the book helps network managers, administrators, and MIS staff/systems analysts understand the theories and practicalities for network protocol stacks.
