Understanding Network Protocols: TCP/IP, IPX/SPX, and More

This chapter explores the essential characteristics of networking protocols including TCP/IP, IPX/SPX, NetBIOS, and AppleTalk. It discusses the role of these protocols in the OSI model, highlighting core functions and addressing schemes. Learn about the planning and configuration requirements for selecting appropriate protocols based on organizational needs, technical expertise, security, and speed. The chapter also compares TCP/IP to the OSI model, detailing the suite's operational layers and subprotocols, including WINSOCK API, FTP, and more.

Presentation Transcript

    1. 1 Chapter Four Network Protocols

    2. 2 Chapter Objectives Identify the characteristics of TCP/IP, IPX/SPX, NetBIOS, and AppleTalk Understand the position of network protocols in the OSI Model Identify the core protocols of each protocol suite and its functions Understand each protocols addressing scheme Protocols on client OSs

    3. 3 Introduction to Protocols Protocols Rules a network uses to transfer data Not magic need planning and configuration The Protocol you choose will depend upon: Existing network Organizations technical expertise Security and speed requirements Does it need to be routable? Span > 1 lan segment Routable because they carry L3 info that can be interpreted by a router. Need > 1 protocol multi-protocol network

    4. 4 TCP/IP Transmission Control Protocol/Internet Protocol (TCP/IP) IP v 4.0 (6.0) Suite of small, specialized protocols called subprotocols Protocol foundation of ARPAnet (late 60s) Advantages Routable Many NOSs and OSs support Disadvantages Management Configuration Design

    5. 5 TCP/IP Compared to the OSI Model Application layer roughly corresponds to Application and Presentation layers Transport layer roughly corresponds to Session and Transport layers Internet layer is equivalent to the Network layer Network Interface layer roughly corresponds to Data Link and Physical layers

    6. 6 TCP/IP and the OSI Model WINSOCK API, FTP, TFTP, HTTP, SMTP, DHCP TCP, UDP IP, ICMP, ARP Formatting of data and transmission to the wire
